New for 2025! Our trusty 41-Thermal® Heat-Treated Thunderbolt cranks sized specifically for the growing DJ/MTB scene.

Based around our test riders' repeated requests for cranks with BMX-level durability, the Thunderbolt DJ crank takes our proven design and adds a longer spindle for compatibility with 73mm Euro bottom bracket shells.

In addition, we also have a 22mm Euro BB specifically designed for 73mm BB’s with a 51.5mm tube spacer.

The Thunderbolt is one of the most technically advanced crank designs on the market. Due to continued advancements in our legendary 41-Thermal® processing and heat-treatment system, fatigue life has been increased by a massive margin.
