Crupi OS20 2.0 Pro 3X Race Frame

FRAME DETAILS: The OS20 2.0 Pro 3X Race Frame is all new for 2025.  Although it still has our race winning geometry, the frame now features wrap around seat stays, a slightly shorter seat tube and our all new built-in Disc Adapter.  Axle mounted adapters are no longer needed!   Our All-American Made frame with a 23" top tube is designed for riders 6'+.  The OS20 set up is great for those who love the stability that the sightly bigger 451mm rim/tire size gives you.  OS simply stands for "Over-Sized" twenty inch wheel that some racers prefer for the stability and the extra rolling diameter of the bigger wheel.  The frame geometry was based on the Answer Dagger OS20 fork but most standard Pro 20" forks will work with the OS20 wheel so you don't need to buy a OS20-specific fork. Level 2.0 Race Frames feature Pro Taper head tubes and use a traditional EB24 Euro BB.  Built with seamless drawn 6061 T6 Butted tubing Tubing is squared off at the ends to provide more welding surface Larger
