EXC 1200 SPLINE® The best in enduro wheels: a blend of carbon and ceramic, agility and stability. With its carbon structure optimized for impact resistance, reinforced rims, and ideal resin-to-carbon-fiber ratio, the EXC 1200 SPLINE is the benchmark in the enduro sector. The naturally strong rim allows for the use of extremely lightweight Aerocomp and Aerolite spokes and ensures optimal stiffness for the entire wheel. At the heart of the wheel, the 180 STRAIGHTPULL hub is paired with extremely smooth-running SINC CERAMIC bearings and the latest RATCHET EXP freewheel system.
