2025 Felt IAx Advanced 105 Di2 Triathlon Bike

2025 Felt IAx Advanced 105 Di2 Triathlon Bike

Get out and go

We have updated the IA to become the IAx. By eliminating the frame/fork nose cone and outgoing one-piece front end we provide more fit options across a wider range of athlete levels. Still a race-ready set-up, the IAx now offers the advantages of a streamlined and simplified design to make bike set-up easier and to keep things simple with overall maintenance and travel to events.

New electronic shifting

The IAx complete with Shimano's updated 105 Di2 groupset. Quick electronic shifts across the 12-speed range and powerful brakes ensure optimal performance for all levels of rider.

Roll for the win

Attack your competitive goals with the aero advantage of the custom Reynolds AR58/62 DB wheelset and Continental Grand Prix SL tires combination. With great handling characteristics and a wind-cheating set-up, you'll see your PR's rack up.

A fitter's friend

Dial-in your riding position with an easy-to-adjust set up on your front end. The aluminum stem, base bar, and extensions offer individual adjustments to get your best riding position.
