What is the difference between Triathlon bikes and regular road bikes?
Triathlon bikes are designed with a different geometry than road bikes. Triathlon bikes are more forward in their seat tubes (between 75-78 degrees) and are set up lower in the front end to provide a time trial position. A steeper seat tube angle emphasizes the quads more to save the use of your run muscles so that you have more get up and go when you start the run portion of a triathlon. Triathlon bikes come in 650c or 700c wheel sizes. 650c wheels accelerate better and are lighter, having less surface area exposed to the wind than 700c wheels. They are more proportional to riders under 5’10”. 700c wheels have long been the standard in the bike industry. Although slightly larger, 700c wheels offer more comfort and less rolling resistance than 650c wheels and are more proportional to riders over 5’10”. Regular road bikes have a slacker seat tube angle, from 72-74 degrees, and are set up for all-purpose riding. They are designed to corner, climb, and sprint well. The road bike positio
