FeltIA 2.0 UD Carbon STD
This is the lower-priced version of Felt's IA 2.0 triathlon bike. The frame and fork are made from Felt's standard UD Carbon STD layup instead of the FRD 12K Carbon Light used on the top builds. The shape, geometry and integration are the same: a THIRSTpac reservoir in the top-tube hump, a CALpac nutrition compartment and an ITSpac tool space in the seat tube. Felt sells it only as complete Expert and Race bikes, not as a framekit.

Our verdict
Overall
out of 100, average of 7 categories
The cheaper way into the IA 2.0's shape and in-frame hydration, nutrition and tool storage, aimed at age-groupers who want integration over outright speed. You give up the top-grade carbon and a power meter, and the complete bikes are among the heavier ones in the catalog.
