The quest for Ironman-winning machinery ends here! Felt's IA series of aero bikes have already won countless events, including the 2018 Ironman in Kona. This version now sports Shimano's Ultegra hydraulic disc brakes for superior stopping power in all conditions. When given the choice, every Felt triathlete at Kona 2018 chose to ride the new disc brake version of the IA. The final result? Daniela Ryf set a new course record for women and beat the men's record bike split time from 1993. Not a bad debut...


The previous version of the IA series changed how triathletes looked at their bikes almost overnight. It was aero, light and surprisingly comfortable. This new disc-equipped version made critical updates to improve performance in many ways:



  • The fork is an all-new design that allows the front disc caliper to perform better

  • The rear triangle is also redesigned to handle braking stress at the flat-mount brake caliper

  • 12mm thru-axles are used for improved torsional strength in the frameset and ensuring perfect disc brake alignment


The IA2 Disc was already an outstanding triathlon bicycle, featuring incredibly low drag thanks to Computational Fluid Dynamic testing and wind tunnel refinement. The frame of this updated version is constructed of Felt's own UHC Advanced + TexTreme carbon fiber, allowing the engineers to use very little resin when building the frame. Lower weight, improved quality control and better durability are all part of the latest carbon fiber "recipe" used by Felt. Internal brake cable routing, flat-mount disc brakes and integrated storage help make the IA2 Disc a sleek package when slicing through the air. The redesigned fork also uses the same UHC Advanced + TexTreme carbon fiber, keeping the bike's total weight very low.


Drivetrain duties are handled by Shimano's revolutionary Ultegra Di2 electronic component group. Instead of cables and housing, servo motors move the derailleurs with lightning-quickness. So quick, in fact, it even prolongs the lifespan of the chain. Shifter buttons are found at the end of the aero extensions and the end of the base bars. With more than one position to operate the drivetrain, the rider can shift while standing out of the saddle. Just try that with bar-end mechanical shifters! Shimano Ultegra front and rear derailleurs are powered by a rechargeable lithium-ion battery submerged inside the seat tube. Charging is done at the junction box at the IA2's head tube. Time between recharges is usually between 900-1000 miles. A Shimano Ultegra 52/36T alloy crankset and 11-28T Ultegra cassette adds a wide gearing range for challenging high-speed courses and fast bike splits.


Deep-section Reynolds AR58 and AR62 carbon fiber wheels cleave the air better than shallow alloy hoops, and are lighter to boot. The deeper the rim cross-section, the lower the drag. Continental Grand Sport Race 700x25c tires keep rolling resistance low as well. The IA2's ISM PS1.0 Adamo saddle is padded for comfort when the rider is in an aggressive position during extreme efforts. It sits atop a wing-shaped UHC Advanced carbon fiber seatpost/mast that reduces the crossing of turbulence from left to right, keeping the air managed more effectively.


The Devox Bayonet 3.1base bar is installed on a direct-mount stem, adding torsional stength when pedaling out of the saddle. The aero extensions and forearm pads are also adjustable, ensuring a comfortable fit for short distance events to long-course IronMan races.


A Shimano charging cable is included with the purchase of this bicycle.
