absoluteBLACK RaceFace Cinch Boost Oval Narrow-Wide Chainring

BOLTS
For Outer chainring please order “Long bolts” OR absoluteBLACK Bolt Covers
Changing Inner chainring only? use original bolts

IMPORTANT

• Ramps on big rings are specially configured for combinations: 50/34, 52/36, 52/38, 53/39T
• If you wish to use other configuration it will also work, but shifting will be slower and may require more “adjustments” of front derailleur to be acceptable. Also remember that front derailleur can only accept max 16T difference between 2 chainrings – this is how Shimano and SRAM designed them.
• Absolute Black always recommends using a new chain when fitting new chainrings.

ADVANTAGES OF ABSOLUTE BLACK ROAD ROUND CHAINRINGS

• One of a kind look
• Super stiff design due to thicker, 5mm construction
• Bespoke Absolute Black 4 / 6 point ramp and recess shifting design shifts as crisp as original
• Finest design that provides excellent strength to weight ratio
