Have you over torqued or rounded the double tapped thread on a 3D, 3D24 or 2INpower Non drive side crank arm?

We can repair that. Price includes drilling out the insert and replacing the DTT bolt and insert with a new unit.

This is not possible without the ROTOR Factory tool, the NDS arm needs to be posted back to us at Velotech.

Purchase this product online and post your non drive side arm back to Velotech, we will complete the work and post back out to you. Turnaround time in workshop is normally 2-3 days. This is a repair service, not a product we despatch before receiving .
