Two words: Fixing e-bikes.

Oversized bore for cables on the axle. Oversized tapered splines for freewheels whose openings don’t engage well with standard tools.

Perfect for getting removing those baked-on cheap clusters.

• Fits Shimano style threaded freewheels
• Large internal diameter to clear axle-mounted e-bike motor cables
• Oversized and tapered outer diameter to firmly wedge in place
• Stainless Steel construction
