B FEATURES

Felt B Triathlon Specific

Triathlon-Specific Design

The B takes its design cues from our top-of-the-line IA, as well as the legendary DA frame kit, which has been ridden to several triathlon world championships and countless international accolades in road bike time trials. These include an aerodynamically optimized, oversized downtube and seat tube, with each sporting unique wheel cutouts to further improve aero efficiency while ensuring a refined geometry for a stable ride quality and precise handling. The bike’s incredible level of fit adjustability is made possible by the use of a standard road-style stem paired with our famous Bayonet basebar, as well as a unique angled carbon seatpost. This means that every triathlete will be able to find his or her most comfortable and powerful riding position.

 

Felt B Triathlon is aero

Aerodynamics

Every racecourse is different, with varying elevation gains, road curvature, and, of course, an endless variety of wind, both in terms of velocity and direction. Our methodology for creating every race bike involves rigorous simulated modeling, wind tunnel testing, and real-world riding of prototypes. Countless new designs are scrutinized, updated, and tested again. In the case of the B, our engineers hit upon a bike inspired by the world championship-winning IA and capable of carrying on the iconic B marque.

Felt B Briathlon Carbon Fiber

Performance Carbon Fiber

Not all carbon fiber race bikes are created equal. Sure, there are countless types, grades, and qualities of carbon fiber used in the bicycle industry. But just like how the finest food ingredients demand the skills of a chef to yield a truly exquisite meal, bicycle frame materials require engineering expertise to produce a truly great bicycle. In fact, many of our engineers would say that our Performance-level carbon bikes like the B presented the most complex engineering challenges of our entire product line. The result is a finely tuned chassis crafted from our Performance-level carbon fiber, with a unique layup that offers a stiff, efficient pedaling interface and a smooth ride for tackling endless miles of training rides and long-distance races.

BIKE SIZING

Getting the proper size bike is key to comfort, performance, and safety. The world's best bike, if the wrong size for you, won't make you a better rider.
Our bike sizing guide is meant to give some general direction as to the best size to fit you based on your height. This is just one variable in a very complex system between rider and bike so keep in mind that rider proportions, fitness levels, and other aspects particular to the individual cyclist has a big impact on how you'll feel and perform on your new bike. Our size guidelines are not a substitute for a professional bike fit. If you have size questions, please don't hesitate to visit your local qualified bike fitter or reach out to us.
