Time-Based Results

The Swift Axis Crank delivers real-time synchronised data from left and right cranks, at a constant data rate.

If you’re implementing Inverse Dynamics using outputs from a crankset, it’s important that your signals aren’t angle-based, that’s where the Axis Crank can help you.

Bottom Bracket

The Swift Axis Crank has a bottom bracket design that provides a 30mm BB tube attached to the crack via a parallel splined interface with internal taper bolts for an expansion fitting.

This strong approach allows fitment to variable BB tube lengths up to 386 styles. The fitment to a standard 68mm BB tube is accomplished using outboard 30mm bearing carriers. Additionally, the safety crank retaining bolts are a secondary safety measure to ensure the integrity of the system. The Bottom Bracket is also available in Aluminium and Stainless Steel.
