With its SL4 FACT 10r carbon frame and fork and vibration damping Zertz inserts, the Roubaix SL4 Pro Disc Frameset has equal parts rapid responsiveness and engineered compliance. Build it up with your dream specs for the ultimate endurance racing weapon.
- FACT carbon CG-R seatpost has integrated elastomer inserts that help dissipate road chatter and vibration, without sacrificing responsiveness or power transfer.
- High-modulus SL4 FACT 10r carbon frame with tapered head tube and compact race design provides incredible responsiveness, while the engineered compliance and Zertz inserts smooth out vibrations and road chatter.
