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.
