Although most road bikes have carbon forks, frame materials differ (mostly based on price). Bike frames are typically made of aluminum at less than $1500; between $1500 and $2200 the frames begin to show some carbon, particularly in the chainstays and seatstays; over $2000 buys a full carbon frame. Not all carbon is alike, however – precision engineering and specific shaping of the tubing affects stiffness and comfort. Steel and titanium bikes are more of a niche these days – high-end “ti” bikes give a supple, smooth ride; steel is heavier, but loved by purists for its lively ride.
Aluminum once had a reputation for being a harsh ride, but frame engineering has come a long way and the shaping of the tubes has made a noticeably good difference. Carbon, too, used to be scoffed at as having a “wooden” or “dead” ride. Again, tube manipulation has changed all that for the better. While carbon will never have the “spring” of an alloy frame, it does deaden road vibration, resulting in less rider fatigue on long rides. Even steel, titanium and aluminum bikes all come with carbon forks to deaden the “road buzz” that would otherwise be directly transferred to the rider’s hands. Carbon race bikes are typically extremely light and stiff. Because of that, they give a somewhat harsh ride and are not recommended for the average rider. Most people appreciate a smooth, forgiving ride – especially on century rides or over rougher roads. Race-worthy bikes are extremely expensive (sometimes up to $15,000) but for the club racer, $3,000 will buy a race-worthy machine that is also durable enough for daily training. |
