Use of this cassette sprocket requires removal of the 17T or 15T cog & spacer from your cassette. If you add one of our 16T cogs, you will remove both the 17 & 15T cogs.
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 only with the following SRAM 10spd cassettes: PG 1030, 1050, and 1070 - 11-36 and 12-36 cassettes, X0 11-36t(XG - 1080) - Remove the 14t rather than the 17t. The only note on hub compatibility is that these fit extraordinarily tight on certain Stan's No Tubes hubs like the 3.30. With a little filing and some grease they will go on.
Compatible with Medium and Long Cage rear derailleurs for 1x10 and a Long Cage is required for 2x10.
