carbon vs alloy frame weight

It's a great way to save some weight and money. I think you will find the carbon fork much, much better in terms of weight, performance and comfort compared to an alloy fork. For example, a Santa Cruz Bronson carbon frame may boast a 1.5-pound weight saving over the aluminum version while the carbon Pivot Switchblade might be 1.9-pounds lighter than the aluminum Switchblade. Check out this guide to repairing a carbon bike for more info. This allows the rider to attempt more challenging trails without having to worry as much about destroying the frame. Brazing sticks the frame tubes with a molten filler material. Please tell me if it's worth spending the extra grand or more specifically for a carbon frame over an alloy frame, is the difference actually worth that kind of money or is it marketing? Found inside – Page 122development of oversize tubing to compensate for aluminum's lower degree of ... the frame sufficient strength, which tends to diminish the overall weight ... Indeed, the introduction of composite rims during the 1990s provided a major leap forward for wheel design and construction. Structural steel is a category of steel used for making construction materials in a variety of shapes. A MTB, Carbon aero bike and an alloy training bike. The components play a major role in the bike’s performance and ride quality. While this is unlikely, it is possible. Summary: A road bike wheel upgrade for well under $1000 can noticeably improve the performance and comfort of your rim brake bike. Different grades of carbon fiber exist. Found inside – Page 104Boasting both a carbon-fiber fork (standard in this class) and carbon seatstays ... Performance's Scattante R-660 features a butted alloy frame with carbon ... I'm getting a fatbike so it looks like carbon fibre is the way to go for me. There is also the fact that having a slightly heavier bike isn't that big of a deal. Unfortunately, carbon fiber is not an environmentally friendly material. Wide, high-volume tires with low air pressure absorb most road noise. It offers an incredibly high strength to weight ratio. For this reason, titanium is an excellent choice for mountain, touring, or road bikes. If you’re buying a brand new bike, this isn’t even worth worrying about. Mostly because the material allows manufacturers to strike a better compromise between stiffness and compliance. Consider how often you crash, whether you’re an elite rider or more casual, how much weight matters, and your budget. steel and titanium on the other hand does fatigue and many of the vintage bikes rode by pros are now in a crumbling stage when tested. Generally, you want your frame to be stiff laterally so you don’t waste energy flexing the frame from side to side as you push down on the pedals. Different section profiles can be formed to be more aerodynamic, less stiff, more stiff, more flexible, etc. Broken top tube of the Carbon Trek Slash 9.8, GearLab is reader-supported. It is not marketing. Carbon, on the other hand, besides being better over time, has a much higher tolerance to frame bending. Value-carbon wheels are usually more aero but heavier than alloy upgrade ones. This is basically burning plastic. I have broken several alloy frames, but that is not saying much. The most common failure points on carbon frames are the bonded junctions. We only make money if you purchase a product through our links, and we never accept free products from manufacturers. All of that aside, IMO, carbon frames are not necessarily worth the cost unless you are after a particular quality (weight being a big one). Check out my steel vs aluminum bike frames guide for more info. The main advantages that steel frames offer over any other material is the smooth ride quality. Let us know! In this section, we’ll compare carbon fiber and aluminum bike frames. Carbon v aluminium. For more info, check out this interesting article about how carbon frames are manufactured. Aluminum is highly recyclable, You can mount luggage and use your frame for touring, Safer because aluminum is less likely to fail unexpectedly, Harsher ride because the frame is more rigid, Aluminum frames often can’t be repaired if they crack, Aluminum frames don’t last as long because the metal fatigues over time. It is a testament to the Integrated Molding Process that SCOTT carbon fiber frames can not only be made extremely lightweight, but that they can also achieve the highest standard for strength and integrity. Material on GearLab is copyrighted. Weight-wise, there’s not much separating the bikes here either. It’s not safe to ride a cracked carbon frame because they can fail without warning. The perception is that if an aluminum product is bent in a crash, it’s the fault of the crash; if the same accident results in a carbon fiber product snapping, the … That's interesting that you got the same time. Steel has some flex. The weight difference between Al rims and Carbon rims is a dead heat. Aluminum itself isn’t strong enough for building bike frames. In this scenario, both bikes might end up costing the same. Also, once a crack or dent has formed in the aluminum tubing, it is difficult to determine the structural integrity of the frame. The frame may suffer a cosmetic dent but still remain rideable. Adding these elements increases the strength to weight ratio of the steel. Carbon fiber frames are lighter than aluminum frames because the material is less dense. Carbon fiber can fail catastrophically and without warning. Comfort Bikepacking bags attach directly to the frame with straps and buckles. The low price is the reason that aluminum frames were introduced in the first place. Share. It takes more man-hours and much of the work must be done by hand instead of a machine. While carbon fibre tubular wheels might appeal to weight weenies, the fact is that the cheaper and more common carbon fibre clinchers are typically the same weight, or heavier, than a good quality aluminium wheelset. There are more parts to the bike then just the frame and I would look to have a well rounded, well fitting bike before spending any money on carbon. When choosing between a carbon fiber or aluminum bike frame, the main differences come down to weight, durability, comfort, and price. This desire for innovation led it to explore the use of carbon and alloy frames in the 2000s. The Transition Smuggler aluminum frame sells for $1999 while the carbon version sells for $2999, a $1000 difference. Found inside – Page 121The aluminum - alloy frame bicycle is the most popular nonsteel type . ... Another popular alternative for bicycle frames and components is carbon fiber ... The primary difference between carbon and aluminum comes down to weight and ride quality. On a carbon bike, the catastrophic failure point is much higher than an aluminum bike due to the flex qualities of the carbon material. Is it worth spending extra on the frame alone, I don't think so. How can we improve GearLab? These tubes form to the mold. Higher quality steel is more expensive, but 4130 cromoly is still affordable when compared to other materials like carbon fiber. Some high-end carbon bikes use modified monocoque construction. 29 inches wheels weigh around 2 pounds more than 27.5 inch wheels. This means you don’t have to worry about your frame getting wet or exposed to salty sea air, chemicals, or road salt and rusting. The geometry of the two frames are almost identical. Rigid aluminum frames can’t offer as much dampening as more flexible carbon frames. You’ll still want to be careful about not overloading the bike. You’ll want to keep an eye on your chain, spokes, rims, handlebars, crankset, derailleurs, and any components that contain steel parts. The bike needs to be stiff so it handles predictably and responsively. Carbon fiber is made by processing a polymer into strings or filaments of carbon atoms that measure 5-10 microns in diameter. It’s more about amount of material used and the tube shapes. Cracks can be difficult to spot. You may want to apply some type of frame protection on these areas. Thanks for the reply, but changing tires/sizes could also make a big difference for alloy/carbon? Therefore, there’s no significant difference between both carbon and titanium regarding weight. Carbon vs. Aluminum. Home » Bikes and Cycling » Carbon Vs Aluminum Bike Frame: Pros and Cons. A catastrophic frame failure is a possibility. Manufacturers can adjust the shape of the tubing as well. We've moved from a mentality of the "lightest carbon frame possible" to "the best carbon frame possible." Modern high-end aluminum frames are almost as comfortable as carbon frames. To be safe, you’ll want to periodically inspect your rear dropouts where the seat and chainstays meet, the head tube where it meets the down tube and top tube, the bottom bracket area, and the area around the seat post clamp. Several different versions of chromoly exist. To inspect a carbon frame, begin by looking for scratches in the paint. I should start this by coming clean; I have a carbon fetish. I stated that carbon wheels make you a better rider. The two share the same frame, but the parallels stop there. An ultralight carbon frame fitted with heavy, low-end components might end up weighing more and performing worse than an aluminum frame fitted with high-end components. Those three bikes will all get the same full-carbon frame – Giant is no longer doing hybrid carbon/alloy frames. Found insideBy contrast, a frame formed from high-performance alloy steel with 85,000 psi (586 MPa) yield strength cuts the frame weight by 30% to 40%, and it is still ... Vertically, you want some flexibility for shock and vibration absorption. This means that an aluminum frame won’t corrode away over time. You’ll find hookless carbon rims spec’d throughout, along with an excellent Maxxis tyre combo – a 2.5in Minion DHF up front and a 2.4in Dissector on the rear. Alloy bikes can be just as stiff. The frame is brazed to the lugs to hold the bike together. As you’ll find out, a majority of the substances often don’t vary significantly with the different alloys. Most entry level road bikes ($700 and up) from the big brands come standard with a carbon fork. In fact, a low-end carbon frame could weight more than a high-end aluminum frame. 11 (1) Brake Type When you chose a carbon frame, you’re prioritizing weight and comfort over durability and price. Alloy (1) Number of gears Total number of gear ratios (number of front gear x number of rear gears. The frames are often butted adding more material where the joints are so that the tubes can be lighter weight and the joints can still be strong. After thousands of miles, these impacts add up to many microscopic cracks in the aluminum, and over time stress failure cracks will appear, typically at the wades, the weakest points. They brought down the cost of bicycles considerably. Just not quite as much as carbon fiber. Having said this, there have been some major improvements in aluminum bike frame technology over the past 20 years that have greatly improved comfort. Steel and titanium are popular choices for custom made or ‘do it all’ types of frames. It’s heavier than carbon fibre so you’ll have to spend a … Or are just cruising around town? bikes So the Mega frame is only 100g lighter than the Giga. 1. However, you should mark the word equivalent. It all depends what you want out of your rides. Weight. Carbon (High-Tensile) Steel. It can be helpful to run a cloth along the frame tubes. Stiff frames make for a harsh ride because the shocks and vibrations from the road transfer straight through the frame to your body. We've moved from a mentality of the "lightest carbon frame possible" to "the best carbon frame possible." Pretty much every bike being raced professionally in both road and mountain biking is made of carbon fiber. There are some athletes who can legitimately benefit from a carbon frame but most people at that level of competition are already sponsored anyway. This guide outlines the pros and cons of carbon vs aluminum bike frames. High-end bikes are almost exclusively made of carbon fiber these days. If you have the money for a carbon frame it would be much more well spent purchasing a titanium frame which has the light weight of carbon, the toughness and wonderful ride characteristics of good steel, and the corrosion resistance of aluminum. While both frames have their breaking points, typically carbon will "bounce" off a rock due to those same dampening qualities that we addressed earlier, while an aluminum frame will tend to absorb more of that impact, sometimes in the form of a dent. The TRP Flow Set Control brakes are available on all models except for the men’s and women’s Disc bikes, which have the Promax F1 brakes, the Sport models that use the Tektro HD-R310, and the V-brake models that have the V-brake, linear pull brakes. Performance-carbon wheels can give you some combination of more aero, lighter, using higher-grade carbon or better hubs than either value-carbon or alloy upgrade wheels. I couldn't really tell if it was that much smoother riding and up on the hoods, probably no faster than the Cannondale hybrid which cost one fourth as much as the carbon bike. Carbon Vs Aluminum Bike Frame: Pros and Cons. The SLR 8.9 Disc brings the fantastic ride quality and aerodynamic performance of the SLR 9 Series bikes down to an even more affordable price point. There isn't that much information out there on this regarding specific impact forces, and we weren't allowed to take an axe to the top tubes of any of the bikes, but we don't feel that carbon is any less susceptible to impact breakage than aluminum and possibly more resistant. You'll feel it in your feet, legs, shoulders and arms. While this certainly won't occur overnight, you should be aware of it. Our Editors independently research, test, and rate the best products. Road touring is more or less the same. Weight Differences in Steel and Aluminum. The M5 alloy bikes do have a slightly lower standover height and are available in an extra small size. Tires, suspension systems, saddles, grips, pedals, and the bike’s frame geometry have a much bigger influence over comfort. Titanium frames can also be lugged. As you can imagine, this isn’t a very green process. Generally, an aluminum frame can handle a harder impact force than a carbon frame without cracking or breaking. Alloy rims are a valid choice for the following reason. Weight vs Aerodynamics. Aluminum frames usually have a harsher and less refined ride than carbon frames. The main drawback to steel is the weight. There are an incredible number of variables that can be adjusted to optimize the bike for performance and comfort. If you want the lightest wheels on a budget, then aluminium is still the way to go. Aluminum can be recycled indefinitely. Found inside – Page 398Weight: 25.5 oz. (Model 3904) or 34 oz. (Model 3906).

There are also other types of aluminum, such as 7075 and 2014 which are very strong, but almost impossible to weld. Carbon frames are usually a bit lighter than aluminum - up to a pound for mountain frames and up to a half-pound on road frames. Some riders consider their bike to be a bit of a status symbol. We feel that the majority of bike owners out there are going to do a full upgrade in the form of a completely new bike, but there are riders out there that will replace just a frame. The raw carbon fiber material can be made with different densities of filaments or different types or amounts of resin. The carbon fibers themselves do not degrade but the resin used to hold them together could in some cases. James Raison James Raison December 21, 2017 carbon fibre bike frames, titanium Vs carbon fibre, Titanium bikes 22 Comments. Think about when and how you'll be riding and choose the frame that's best suitable for your needs.

Having said this, if you crash hard enough, you can destroy an aluminum frame. Amazing article. That being said, I've heard that CF can be much more comfortable on long haul rides as opposed to alum. I've heard it's strong enough to take into the mountains in Alberta. This is because the bike, including the headtube, downtube, seat tube, and top tube, is made as a single piece. Regardless, carbon is actually repairable while aluminum, not so much. Fitness and skill are far more important than bicycle weight. I even have a KOM on one lightly traveled segment where I rode both my Schwinn and Cannondale back-to-back and amazingly got the exact same time on both rides that day. I also have a giant tcr haha and I love mine, It is absolutely not worth the money. edit: and saddle. This eliminates some of the most common bonded junction failure points. Titanium frame tubes are welded together, just like steel or aluminum. Carbon frames have superior ride characteristics, including handling, responsiveness, and comfort. 195+18=213lbs. but what about an aluminum fram and a carbon fork and carbon seat stay-bike Way back in 2001 bike engineer Kraig Willett analysed the forces on wheels and concluded: "When evaluating wheel performance, wheel aerodynamics are the most important, distantly followed by wheel mass. This material is then shaped into bike frames using molds and heat. And it is 7.023 kg. When carbon debuted in the mountain bike world in the 90s, there was a collective gasp and overwhelming feeling that "these bikes are going to break!" Great article. ... still got a carbon frame here. Therefore, a carbon frame needs to be very carefully assessed after a heavy crash. Bicycle Saddles and Seats. Corrosion isn’t really a concern with either carbon or aluminum frames. They can vary the direction of the carbon fiber. Road touring is more or less the same. This involves heating then cooling the entire aluminum frame in a controlled manner. You’ll have to compromise somewhere. How long your aluminum frame lasts depends on the type of riding you do, how you treat it, and the quality of the aluminum and welds. The Weight Difference. this interesting article about the different grades of carbon frames. Cannondale is known for its willingness to explore new techniques. For this reason, carbon frames are not recommended for bicycle touring or bikepacking. They are incredibly expensive. At the heart lie Boardman's C7 frame and fork, which use the same aerodynamic design and geometry as the rest of the SLR range, albeit here with a different grade of carbon fiber. A proper high end carbon bike is engineered with more and less carbon on different parts of the bike to give stiffness and comfort at the same time. Carbon or high-tensile steel is a good, strong, long-lasting steel, but it isn't as light as its more high-tech brother, the steel known as chromoly. The difference is pretty minimal. After all, it’s the cheapest bike frame material. This allows for a good amount of control over the ride quality, stiffness, and responsiveness. The reason is that carbon fiber is not really recyclable. This guide covers both mountain and road bikes. Find out what the strengths, weaknesses and who should buy the bike. Press question mark to learn the rest of the keyboard shortcuts. Almost every high-end bike is carbon these days. In fact, carbon fiber is the lightest bike frame material in use today. Are you entering in races? A lighter bike allows you to climb and accelerate faster and maneuver more easily because there is less weight to move around. Aluminum is the cheapest bike frame material. Much of the process can be automated. The benefits of carbon composites are well known, where the low weight and high strength of the material accounts for the majority of its appeal. Found inside – Page 355Due to magnesium's relatively low modulus of elasticity , the frame's weight is comparable to a light weight steel or aluminum frame . Steel and carbon ... The bike now weighs 20.9 pounds and the handling and performance is light years different. Of course, even if the frame can’t corrode, that doesn’t mean that other components can’t as well. Inspect the bottom bracket threads, headset race, and rear dropouts. Of the two, 6061 is slightly superior due to its lower weight. Thank you for reading! It is also extremely rigid. If you are not racing alloy is much better, less maintenance and headaches, cheaper. Carbon fiber has an incredibly high strength to weight ratio. Chromoly is a steel alloy made by combining steel with chromium and molybdenum. In fact, most of us could stand to lose the extra 1-3 pound difference between the frame materials. For example, engineers can change the thickness of the carbon fiber with extreme accuracy by varying the number of layers. The extra weight of course comes from the larger tires. Found inside – Page 10However , these bicycles are at the high end of the carbon fiber composite bicycle price range . Material Alternatives Steel - alloy frame bicycles still ... In theory, carbon frames last longer because carbon fiber doesn’t fatigue like aluminum. Carbon is lighter and tend to provided a more comfortable ride. The safest option is to use a trailer. Just as one impact of this nature could break an aluminum frame and not a carbon frame, repeated stresses in this manner would cause an aluminum frame to break sooner as well. The best thing about this article is now I understand why almost all e-bikes are aluminium, as carbon fibre just cannot take the additional weight of the battery, motor and other components. Just curious here, I was under the impression that it wouldn't really flex much vertically, but I know very little about carbon fiber bikes. If you decide to do this, remember that you’re taking a chance. 6061 and 7005 are the two most common aluminum alloys used for frame building. Amateur racers who buy their own bikes may also enjoy the cost savings. In other words, making the tubes thinner where they don’t need as much strength. Carbon frame repair is a job that’s best left to a professional framebuilder who knows what they’re doing. One of the most discussed aspects of carbon fiber frames is the weight savings over aluminum frames. Carbon Fiber vs Aluminum vs Steel vs Titanium. Aluminium road bikes Aluminium was the leader when it came to frame material before carbon become more accessible. ... which keeps your wheels dished and true way better than an alloy rim. It is a steel that is stronger than carbon steel (more commonly used in bike manufacturing), so we can use thin wall tubing, giving you a lightweight frame that will last through years of riding. Found inside – Page 16The weight of the aluminum alloy frame Walloy : (density of aluminum alloy/ ... the frame made using carbon-fiber composite will be Wcf : (density of carbon ... Many manufactures offer complete 15 lb (6.8 kg) carbon road bikes. Aluminum is a bit more limiting material to work with. But I still prefer steel over anything else. The most popular is 4130. Carbon fiber frames, on the other hand, aren’t really suitable for carrying luggage. As the saying goes ‘steel is real’ In fact, it was the only modern frame option up until the mid-1970s when the first aluminum bikes became widely available. The Ergon CF3 carbon seatpost requires 69N of force to flex one vertical millimetre (0.04″). Titanium really offers the best of all worlds. Carbon fiber bikes these days are much better than they were in the past. By buying the carbon frame and swapping the parts over, you have saved a whopping 0.47 percent in weight. Particularly with modern techniques.

It’s not a secret that it’s a lot easier to fashion a Carbon frames are more efficient than aluminum frames. This is possible because carbon fiber can be fine tuned much more than aluminum. Alloy wheels tend to flex more, or in bike industry terms, they’re “more compliant.” The added compliance can offer more traction, a smoother ride and a more damped feel. They can just take more of a beating. Found inside – Page 68Aluminum ? Carbon fiber ? Balsa wood ? The ride , weight , feel , and price of a bike are all affected by what tubeset material the frame builder uses in ... Before carbon fiber became affordable and accessible to cyclists, aluminum was the most common frame material. For more info, check out my guide to choosing a touring bike. The RC520 is supposedly a very comfortable bike and the Reacto gets knocked for not being too comfortable, but I've found it to be the opposite. The density of modern carbon fiber is about 1.9 g/cm^3 compared to aluminum which has a density of about 2.3 g/cm^3. A note about accidental damage: One major drawback to carbon fiber is that it’s pretty easy to accidentally crack it. Most carbon frames can’t accept racks and panniers because they put too much stress on the frame tubes. You’ll find hookless carbon rims spec’d throughout, along with an excellent Maxxis tyre combo – a 2.5in Minion DHF up front and a 2.4in Dissector on the rear. In some cases alloy wheels can be lighter than carbon. Like aluminum, steel can also be butted to save weight, just like aluminum. Found insideWeight: 9.9 oz. or 11 oz. Ramp front sight, notched frame rear. Aluminum, carbon fiber, stainless and titanium construction. Brushed aluminum finish. While both materials can be made into responsive, comfortable, and lightweight frames, they each have some strengths and weaknesses. Finally, the frames are heat-treated for strength. The increased efficiency allows you to travel further using the same amount of energy that you would on a comparable aluminum frame. I recently moved from a Triban RC520 (alloy) to a Merida Reacto (Carbon). Most of the bikes ridden at World Cup/Enduro World Series level will be carbon (although it isn’t ubiquitous) but it would be simplistic, and maybe even wrong, to say that carbon is objectively better. Impacts and abuse aside, carbon doesn't fatigue over time and your frame will be as good in 20 years as it was the day you bought it, although heckling will probably increase, as might your belly. The frame can be laterally stiff while still absorbing some vibration. Advantages and Disadvantages of Steel Frames. A titanium frame that is equal in strength to a steel frame is about half the weight and half the stiffness. You can’t just crank down until a bolt or screw is tight like you can on a metal framed bike. Top of the line aluminum frames weigh about a half of a pound more than carbon frames. You can also accidentally crack a frame by overtightening components, Harder to carry luggage because you can’t mount racks and panniers to most carbon frames, Bad for the environment because carbon fiber is not very recyclable, Safety can be an issue because carbon frames can fail without warning if they are compromised, More durable.
