HUP DM 3-bolt Narrow-Wide Chainrings (for HUP 2-piece cranks)

A direct mount (SRAM 3-bolt) narrow-wide chainring designed to keep chains securely in place. Compatible with all 9, 10,11 or 12 speed chains (including SRAM Eagle) with 3mm offset for boost chainline and 6mm offest for non-boost chainline.

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.
