We love Felt Bikes and the IA is their most aero triathlon bike. Here's the info and spec from Felt:
The latest version of our venerable IA platform, the IAx sets a new standard for ease-of-use and dialed performance for those who crave speed.
IAx | ADVANCED | Ultegra Di2
- 2x12-speed Shimano Ultegra Di2
- Reynolds AR58/62 DB Custom wheels
Felt's very first bike was made for one of the greatest triathletes in history—Paula Newby-Fraser—who rode her stealth black Felt B2 to multiple world championship victories. Since then, they’ve never stopped pursuing the ideal triathlon racing machine. The IA is the culmination of 30 years of iterative design and painstaking development, and its results at the highest level of competition speak for themselves. So we can tell you that the IA is the most aerodynamic bike in the world. Felt can also say that it’s the best-handling triathlon bike on the planet. But what we should really mention is that the IA won the Kona World Championship a staggering six times in a row, and it holds both bike and overall course records across the lava fields of Hawaii. So, really, what else do you need to know?
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. After endless simulated modeling, wind tunnel testing, and real-world riding of prototypes, countless new designs were scrutinized, updated, and tested again, the cycle repeating anew. The result is a bike worthy of carrying on the legendary IA name, one also featuring the improved performance that disc brakes bring to the riding experience. It’s not merely fast in a straight line—it’s faster in all conditions.
DISC BRAKES & THRU-AXLES
Disc brakes are the best means of controlling a bicycle. Period. Plus, they perform better in adverse weather conditions. Wherever the road takes you, and in whatever conditions you find yourself, the disc brake-equipped IA gives you the confidence to tackle any racecourse. To accommodate the added stopping forces provided by disc brakes, the IA features thru-axles rather than traditional quick-release skewers. It’s a proven design that provides a more secure interface between the bicycle frame and the wheel, which also enhances the stiffness of the frame-and-wheel connection. We also offer a version of the IA with rim brakes for athletes who still prefer that classic feel.
STORAGE SOLUTIONS
The IA comes equipped with Felt’s latest top tube storage solution, the integrated CALpac 2.0. This storage unit features ample space for all of the riding essentials to which a rider needs quick and easy access. Likewise, the IA includes the BTSpac storage device, located behind the seat tube. This unit is ideal for a flat tire repair kit and/or on-the-go tool kit, or any other items that a rider doesn’t require while pedaling on the bike. It’s shape has been aerodynamically optimized for the IA, meaning that it creates no penalty in terms of aerodynamic drag.
THE FAMOUS IA SPEED NEWLY-CONFIGURED FOR PERFORMANCE
The IA has been the most successful triathlon platform Felt has ever created. As we introduced the IA 2.0 and its industry-leading technology, we updated the prior IA to become the IA "x". This "new" version eliminates the nose cone and one-piece front end from the old version to help with more fit options across a wider range of athlete levels.
SHIMANO ELECTRONIC SHIFTING EXCELS
IA speed in a streamlined package complete with Shimano's performance-oriented Ultegra Di2 12-speed groupset. Dialed shifting and beautiful ergonomics ensures a great ride and the technology triathletes demand.
AERO-OPTIMIZED WHEELS
Reynolds' AR58/62 DB wheelset is custom-made for us to ensure the best of aerodynamics and ride quality whether you are training or racing. Premium Continental Grand Prix SL tires offer a sure-footed performance.
PRECISION FIT IS DIALLED
Our aluminium stem and base bar are paired with carbon extensions to provide an easy-to-adjust set up on your front end. With fit a premium in triathlon, you'll have the options for your unique position.
