30 Tooth CNC Sprocket & Adapter Assembly

High-performance parts. Superior quality.

This unit solves the most basic problem with most kits, sprocket alignment. Make the sprocket run true by mounting directly to the hub, not the spokes. The unit should be installed loosely on the hub to allow the unit to slide in and out to find perfect alignment, then tighten and lockdown.

Made of CNC aluminum for superior quality and performance.

Available in 3 hub sizes:

• 1.0 inch - For Freewheel Hubs
• 1.5 inch - Most Coaster Brake Hubs (CB-110 and HiStop)
• 1.8 inch - Larger Hubs
