SHIMANO DM DROP-STOP B CHAINRING - BOOST

These chainrings are for Shimano direct mount cranks. The Wolf Tooth chainrings feature our patented Drop-Stop® design for the best wear life, chain retention and mud clearance.

COMPATIBILITY

• Shimano XTR M9100, XT M8100, SLX M7100, and Deore M6100 series 12 speed cranksets.


• Super boost cranksets -models M8120, M8130, M7120 and M7130 - use the Boost chainring. These Super Boost cranksets have a longer spindle and do not use the Super Boost chainring. These cranks and ring should ONLY be used on bikes with Super Boost rear hub spacing (157mm)


• Boost cranksets - models M9100, M8100, M7100, MT610 - will use a Boost ring with Boost rear hub spacing (148mm) and a Super Boost ring with Super Boost rear hub spacing (157mm).


• Use Drop-Stop B for all chains, except Shimano 12-speed Hyperglide+ and Campagnolo 13-speed chains.

DROP-STOP TECHNOLOGY

Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile delivers ultimate chain retention and mud shedding ability.

RECOMMENDATIONS

• We recommend the use of a clutch style rear derailleur for the best chain security.


• For a longer lasting and more durable option, check out the CAMO System that offers stainless steel chainrings.
