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.
Howitzer Bottom Bracket System
Hit me, beat me, hurt me. Thank you. The Howitzer Bottom Bracket System is purpose-built for Freeride and DH abuse, with CNC machined AL-6061 cups, a chromoly spindle and extreme strength throughout. Oversized cartridge bearings produce a super durable external BB system that’s also agile. You can even switch bikes but keep your favorite cranks by getting a Howitzer BB that fits your new ride.
A single mass of premium AL-7050-TV alloy is pushed, pulled and squeezed into a hollow crank arm. Result? Supreme strength without the tank-like weight. We weren’t the first to fabricate hollow crank arms. But we’re the best. You won’t find a higher stiffness-to-weight ratio. Our Open Core Technology cranks are stiffer, stronger, and lighter weight than any solid forged crankset.
