Felt IA Advanced Disc Ultegra Di2 Triathlon Bike 2020

Felt has once again produced the Triathlon bike that destroyed the field at the Ironman Kona World Championships, adding a 6th title to their winning streak. Felt's IA Series has now not only won 6 years in a row but also holds multiple bike course records over both the full and 70.3 distances, including across the Hawaiian lava fields. As one of the most advanced and aerodynamic triathlon bikes in the world, Felt has to find unique ways to beat not only their own bikes but other competitors as well; that's why to create the IA Advanced they used a wide range of different carbons in order to optimise each area as much as possible. Ultra Hybrid Carbon is the main fibre featured which provides the frame with rigidity and stiffness that allows your pedalling efficiency to be optimised and ensure's the handling is incredible. Unique to the Felt IA Advanced is the incorporation of TeXtreme carbon fibre in order to provide strength as well as being reliable and durable and still maintain it's lightweight properties. The IA Triathlon Bike is also designed with size-specific geometry with five different frame sizes available to find one that keeps you comfortable whilst ensuring your performance stays at it's best by keeping your pedalling efficient and handling optimised. This model features Shimano's Ultegra Di2 groupset which takes your performance to the next level with agile and smooth shifting that's also reliable, taking your performance to some new personal bests. Fitted with hydraulic disc brakes allows you to go that much faster in your descents with the ability to control your speed much easier as they provide you with greater stopping power, making for a speed king or queen out on the course. And finally, Felt has ensured all your triathlon needs are met with two storage units built into the Felt IA Advanced. First of all, the IA features a BTSpac which is ideal for a puncher repair kit to be stored easily just behind your seat tube. Secondly, the CALpac 2.0 storage module which has been integrated into the top tube to make for quick access to nutrition as well as ensuring it doesn't impact your aerodynamics. If you're ready to take your racing to new heights of personal bests, the Felt IA Advanced Disc Ulterga Di2 model is ready for you.

Full Specification


The IA Series

The IA is the most aerodynamic triathlon bicycle in the world. It boasts a heretofore-unseen level of integration that offers a fit range to accommodate the needs of all athletes without sacrificing one gram of aerodynamic drag. But here's all you really need to know: The IA has propelled Felt athletes to victories at the Kona World Championship for a staggering six years in a row, including a bike course record.


Size Specific 

Felt has produced a thoroughly modern geometry that provides both agile steering and stability at speed. The IA comes in five different frame sizes, with each one receiving size-specific designs and constructions so that every athlete, no matter what size frame he or she rides, experience the same incredible handling, pedalling 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. IA models equipped with disc brakes, like the IA | Advanced model you see here, can accommodate tires up to 28mm wide (measured at the widest point, per ISO safety standards that call for 4mm of clearance on either side of the tire and the bicycle frame).
