ONEUP 104 BCD CHAINRING

OneUp your complete drivetrain with our new Narrow Wide Chainrings.  
 
- Narrow Wide tooth profile eliminates chain drop with the perfect chain mesh fit
- Perfect chainline with 2mm Shims included with 32T and 34T rings (30T rings have built in offset).  For a quieter drivetrain with improved chain wear and best drop performance.  
- Reuse your existing 8-10mm long ring hardware. No new bolt packs required, saves you $15.
Aggressive crud chamfers for awesome mud shedding performance and extended ring life.
- Reinforced Wide tooth design provides maximum ring durability when run without a bash.
- Made from hard wearing 7075-T6 aluminum plate

- 30T rings have integrated shims and chainring bolt threads to allow the smallest ring size possible on a 104 BCD crank (loose shims are only included with the 32T-36T sizes).

 

*Shims - Included with 32T and 34T rings. For 2x crank conversions, shims between the crank and ring get you back to an ideal 49-50mm chainline. For 3x crank conversions, shims under the bolt heads allow reuse of your 3x hardware - No new bolt packs required!
