Felt Bicycles IA 2.0 | Expert | Ultegra Di2

Our patented InternaLoc 2.0 seatpost system provides security, adjustability, and comfort. The IA 2.0 has the most advanced version of InternaLoc we've ever made. Its dual-bolt clamp allows for super-fine adjustments to your riding position while preventing post slippage. Its all-new, co-molded sleeve securely enfolds the seatpost mitigating high-frequency vibrations for a smooth ride quality.

To ride faster, you have to get more aerodynamic. The IA 2.0 steps away from traditional frame design to free you from the restraints that hinder speed. The IA 2.0's revolutionary design and striking silhouette represent the pinnacle of form following function. Bottom line: The IA 2.0 is our fastest bike ever.

The IA 2.0 can be set up with all current tri drivetrain options. Electronic or mechanical, 1x or 2x, it's all good. The IA 2.0's unique front-end includes a cover to securely conceal either a SRAM BlipBox control unit or a Shimano electronic junction. If you prefer a 2x drivetrain, then the IA 2.0 can accept up to a 42-tooth inner ring. If you're a 1x fan, you can fit up to a 52-tooth chainring.

The IA 2.0 offers extra storage to keep your nutrition handy. It provides access for a full day's assortment of energy gels, nutrition bars, and other small items. Everything about the new system is built for speed, including a refined version of the slot along the top that allows for easy access in the moment.
The IA 2.0's new THIRSTpac hydration module sits below the CALpac storage compartment and gives nearly 1L (30 ounces) of hydration capacity. It's quick-fill port fills at an aid station and without spilling. The THIRSTpac was designed in conjunction with the IA 2.0's aerodynamic package, which means that it's perfectly integrated into the framewithout any compromise to speed.
