Stiff and rigid design means that each pedal stroke pushes more power and energy into your tires for a more efficient ride. Built with Rotor 30mm UBB axle, these cranks are compatible with almost every bottom bracket on the market.

  • Made of CNC machined 7055 aluminum.
  • Trinity Drilling System creates a trellised design that offers exceptional stiffness-to-weight ratio in the crank arms.
  • 30mm aluminum UBB axle is compatible with almost all bottom brackets on the market, making installation a breeze.
