Felt’s most popular triathlon frame



Our most popular triathlon frame, featuring the timeless feel of mechanical shifting, realized by Shimano’s smooth-actuating and efficient Ultegra components.


  • Shimano Ultegra mechanical groupset
  • Hydraulic disc brakes
  • Includes proprietary storage solutions

Triathlon is unlike any other form of racing on earth, and it presents some of the most unique equipment demands anywhere in the sporting world. The best triathlon bikes must be fast, of course. But they must also be able to elevate the biomechanical performance of their riders in between a grueling swim and a soul-shattering run effort.

The bikes in the Felt IA Advanced line are crafted from several unique types of carbon fiber. The primary material is UHC (“Ultra Hybrid Carbon”) Advanced fiber, which is high-modulus, meaning that it’s incredibly stiff to maximize pedaling efficiency and handling feedback. Though it’s not quite as stiff as its more expensive sibling, UHC Ultimate (which is found on the Felt IA FRD Disc). However, this makes the UHC Advanced fiber is a better option for most triathletes, as it helps yield a slightly more supple chassis to mitigate road feedback and suppress rider fatigue towards the end of a long race.  TeXtreme is another type of carbon that is not only found on our best-performing bikes, but is also utilized in the aerospace industry and on Formula One race cars to both add strength to a structure, as well as reduce its weight relative to alternative composite options.

Beyond its materials and construction methods, the most important thing needed in a world-class triathlon bike is geometry. This determines how the bike handles straight-line accelerations, tackles technical turns, and adapts to the unique fit needs of each and every rider.  The IA comes in five different frame sizes, with each one receiving size-specific designs and construction so that every athlete, no matter what size frame he or she rides, experiences the same incredible handling, pedaling efficiency, and fit adjustability.

Two unique storage solutions provide room for all the gear you’ll need for any training ride or race: the BTSpac sits behind the seat tube and is ideal for a flat tire repair kit or other tools, while the CALpac 2.0 storage module is integrated along the top tube for quick access to nutrition products or anything else you want at your fingertips.

An incredible frame demands the best componentry to truly maximize the racing experience.

WEIGHT21.76 lb, 9.89 kgWEIGHT DISCLAIMERThe most accurate way to determine a product's weight is to have your local dealer weigh it for you. Because we understand that weight is an important metric, we strive to list it when possible. When listed, weight is based on a single sample in a specific size and with all items as shown in the photo. It is not an exact indication of what your bike or frame will weigh, as there are tolerances in many variables involved (size, finish, hardware, components, and accessories). Felt continues to be an industry leader in weight and performance.
