AL-7050-TV

Our AL-7050-TV aluminum isn't just strong. It's benchmark strong — 75% stronger than the 6061 aluminum commonly used at this level. Impressive in its raw state, AL-7050-TV ups the ante to bulletproof status through the extrusion, forging and heat-treatment processes that create our pro-level Holzfeller OCT, Holzfeller, Omnium, Rouleur, and Stylo components. It's why our Holzfeller OCT crankset gives you double the pedal thread and BB interface strength of 6061-T6 cranks. AL-7050-TV. Benchmark stiff. Benchmark strong.

OCT (Open Core Technology)™

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.
