The B is one of the most legendary badges in triathlon history and has long reigned as a symbol of the blood, sweat, and tears shed by the most devoted triathletes and the dedication put into every single one of our bikes. The latest iteration of the B is ready for action, featuring an updated frame design gleaned from decades of designing the most aerodynamic bikes on earth and a lightweight carbon fiber construction. Whether you’re just starting your journey into the world of triathlon or a multi-sport veteran, say hello to the B.
With a carbon frame designed with aero efficiency, the B features a finely curated selection of components that offers performance, convenience, and value.
The B takes design cues from our top-of-the-line IA and the legendary DA frame kit. It 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, each sporting unique wheel cutouts to improve aero efficiency while ensuring a refined geometry for stable ride quality and precise handling. In addition, the bike's incredible level of fit adjustability is made possible by using a standard road-style stem paired with our famous Bayonet base bar and a unique angled carbon Seatpost. As a result, every triathlete can find their most comfortable and powerful riding position.
Every racecourse is different, with varying elevation gains, road curvature, and, of course, an endless variety of wind 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.
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 genuinely great bicycle. Many of our engineers would say that our Performance-level carbon bikes, like the B, presented our entire product line's most complex engineering challenges. 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.
