Hellyer Track Chainrings

This is not just any precision machined piece of 7075-T6 aluminum. We've polish it up so it looks nicer or as nice as the one you are replacing. The drilled holes give it a distinct look and lightens it up. We also machine out the back to further lighten it up.

- Also available in 130BCD
- 44, 46 or 48 tooth versions
- Black or Silver
- For 1/8" chains only
