HUP 104bcd 4-Bolt Narrow-Wide CX/Road/MTB Chainrings

A four bolt 104 PCD narrow-wide chainring designed to keep chains securely in place. Compatible with all 9, 10,11 or 12 speed chains, including SRAM Eagle.

These HUPcc chainrings are CNC machined from 7075 T6 aluminium in the UK. Alternating narrow-wide profile teeth help reduce sideways movement in rough terrain which normally derails chains. Complex precision machined debris gullies help evacuate mud for all weather performance.
