Our best 7050 alloy and OCT hollow forge technology combined in a best-in-class DH crank 75 grams lighter and 10% stiffer than our Holzfeller. This is the strongest and lightest extreme-use crank in the market. Period. Bash Guard meshes with our Box Guide for awesome chain management.
To fabricate our Open Core Technology a single mass of premium alloy is pushed, pulled and squeezed into a hollow crank arm. During our exclusive process the magic happens, producing supreme strength while remaining weight-conscious. We may have not been the first to fabricate hollow crank arms, but we are the best by yielding the highest stiffness-to-weight ratio out there. Our OCT cranks are stiffer, stronger, and lightweight beyond any solid forged crankset and when we use our AL-7050-TV to fabricate with OCT the results are impressive.
