Warp 9 Eride Pro 12.9 Cryo Steel Rear Axle (12mm)

A 12mm rear axle for the E-Ride Pro 3.0 and SR, machined from 12.9 grade steel and cryo treated. Cryo treatment is a deep-freeze cycle that refines the steel's grain structure; Warp 9 rates the result at three to four times the strength of the original axle and about twice that of titanium.

A matching Fuji lock nut is included, and both the axle and the nut are black oxide coated for corrosion resistance. Warp 9 backs it with a lifetime warranty against bending or breaking. This is the 12mm size and fits the 3.0 and SR only, so measure the axle currently in the bike before ordering, since other E-Ride models use a different diameter.
