Use of these cassette sprockets requires removal of the 17T or 15T cog & spacer from your cassette. Derailleur B-screw: On occasion some derailleurs may require the use of a longer "B Screw" although unlikely with SRAM derailleurs a portion of SHIMANO derailleurs may benefit from one. Usually an M4 x 25 socket head cap screw from any hardware store - (it does not need to be from your LBS).You may need a longer chain than is presently on your bike, to allow the derailleur to wrap enough chain around your largest sprocket and front chain ring. Aerozines 40T & 42T Sprockets. Are compatible with most 10 speed medium or long cage derailleurs, as long as the derailleur allows enough chainwrap capacity for your selected gearing.
Check to see that the chain length is set properly. With the chain in the largest front chainring and in the Aerozine Sprocket verify that the derailleur still has enough range of motion to take the tension off the chain.
If you have a full suspension bike you will want to verify that the chain does not get tight through the full range of the suspension movement. With the chain is the smallest front chainring and in the 11t cog make sure that the spring on the derailleur is still engaged to keep the chain tensioned.
There is an included spacer that must be positioned differently if youre running SRAM or Shimano, but the directions make it plenty clear.
