Sram Dm Mtb 8 Bolt Drop Stop B Chainring Boost

Our new Direct Mount Chainrings for SRAM 8-Bolt Mountain Cranks are optimised for the new SRAM Transmission mountain groupsets and T-Type chains. These are for riders who have the latest SRAM T-Type Transmission groupset and want a different chainring size beyond stock offerings, or who want to upgrade to a Made In USA option with an optimised tooth profile for better performance.

The 3mm offset is for SRAM MTB cranks with DUB WIDE spindles that are already at the 55mm chainline required for SRAM T-Type Transmission groupsets.

COMPATIBILITY

• These direct mount chainrings will replace your existing chainring and spider or replace a direct mount chainring for SRAM T-Type Transmission cranksets and other SRAM cranks that use the 8-bolt standard.
• SRAM T-Type Transmission DUB Wide MTB cranksets use the 8-bolt direct mount standard.
• Chainline of 55mm with 3mm offset for DUB Wide MTB

DROP-STOP TECHNOLOGY

Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability. Drop-Stop B is compatible with all chains except Shimano HG+ and Campagnolo 13-speed chains.

RECOMMENDATIONS

• We recommend the use of a clutch style rear derailleur for the best chain security.
• Use the included custom T20 bolts. Torque 4Nm with T20 tool
