The Felt IA 2.0 Race 105 Di2 Bike is the entry point into one of the most aerodynamically considered triathlon platforms available. The IA 2.0's defining feature is its curving integrated aero architecture — a distinct humpback carbon form that channels airflow while housing an integrated hydration and nutrition system directly inside the frame. Felt's wind tunnel testing shows the IA 2.0 is 4% faster than the original IA across the yaw angles riders encounter most on race courses, and it made headlines when Daniela Ryf rode it to victory at the Ironman World Championship. The Race 105 Di2 build brings this platform to a broader range of athletes at $6,899.

The drivetrain is Shimano 105 Di2 (R7150) — fully electronic shifting on a groupset that has proven capable at every level of competitive cycling. For triathlon in particular, Di2 matters: the SW-R9160 satellite shifters mount directly on the aerobars, so you can change gear without leaving your aero position. The 52/36t crankset pairs with an 11-34t cassette, covering a range that handles the sustained flats at Kona and hillier race venues alike. Wheels are Vision Metron SC 60 i23 — 60mm deep carbon clinchers that deliver meaningful aero performance without requiring a wheel upgrade on day one. TRP HD-T910D hydraulic disc brakes, designed to work with the Di2 system, provide consistent stopping power regardless of conditions.
What sets the IA 2.0 apart in the triathlon market is its integration. The humpback frame profile houses a 0.9L ThirstPac removable hydration reservoir inside the top tube, with a drink tube that routes to your aerobars. A quick-fill port allows you to top it off at an aid station without stopping. Sitting above that is the CalPac, a 0.2L nutrition storage compartment. This isn't a bottle cage adaptation — the system is engineered into the carbon frame geometry, optimized aerodynamically, and designed not to spill or slosh at race pace. On a long-course bike, that integration is the…
