Availability: 1 In Stock

Wolf Tooth Shimano GCs replace a cog on compatible SRAM 10-speed cassettes in order to provide extra low range for your 1x drivetrain.

-Compatible only with the following SRAM 11-36 and 12-36 cassettes: PG-1030, 1050, 1070 and the XG-1080
-Remove the 14T cog on the XG-1080 instead of the 17T
-SRAM GC42s are not compatible with 2011 or older SRAM rear derailleurs
-Compatible only with the following SRAM 10 Speed Cassettes: X5 11-36T (PG-1030), X7 11-36T (PG-1050), X9 11-36T (PG-1070), X0 11-36t(XG - 1080) - Remove the 14t rather than the 17t
-Per Wolf Tooth, the GC 42 is not compatible with 2011 or older SRAM rear derailleurs due to the position of the upper jockey wheel. The best ways to tell the vintages of your rear derailleur is 1) If you have a type 2 (clutch type) rear derailleur it is 2012 or newer and 2) the upper jockey wheel on 2012 and newer rear derailleurs are offset from the derailleur cage's axis of rotation.Wolf Tooth does not recommend using the GC 42 if you have a pre-2011 SRAM 10-speed mountain derailleur

Almost too big...Almost

This cassette sprocket is only for use with Shimano brand 10spd XT & XTR cassettes. It is NOT compatible with any other brand or model of cassette. The shift points are properly timed to the tooth locations on the 36t Shimano cogs for optimal shifting performance.

Use of this cassette sprocket requires removal of the 17T or 15T cog & spacer from your cassette.

IMPORTANT TO NOTE

Use of this cassette sprocket requires removal of the 17T or 15T cog & spacer from your cassette.

Note on B-screw: We have found a longer screw is almost never needed with SRAM derailleurs and only needed for about 50% of Shimano derailleurs. We have added it as a separate item in our accessories category. If you think you might need the longer B-screw, order one separately or just go to your local hardware store and pick up an M4 x 25 socket head cap screw.

You may need a longer chain than what is presently on your bike. Make sure that when shifted to the 42T cog, there is still some amount of forward travel possible with the rear derailleur cage. This is especially important on bikes with rear suspension. We have tested with Shimano, KMC & SRAM chains all function well.

Compatible with the following Shimano 10spd cassettes: XT 11-36t (M771), XTR 11-36t (M980)

Compatible with SLX (HG81) 11-36 cassettes only if you are willing to drill or cut the rivets holding the 17t cog.
