IMPORTANT NOTICE

BE WARE OF BACK PEDALING ISSUE

If your rear derailleur's factory setting does not support a cassette of this range, when you back pedal or move the bike backwards,the chain may drop from the larger cog. In this case, if you do not adjust the chain to the right position and ride the bike anyway, there will be a great chance that you will damage your chain and your cassette. We are now working on new model to solve this problem. If you ride your bike forward, the shifting will be just fine, and you don't need to worry about the drivetrain.

DERAILLEUR WITH CLUTCH OR HIGHER TENSION RECOMMENDED

Wide ratio cassettes are usually heavier than stock cassette, that means higher inertia, if your rear derailleur can't handle the extra force by high gears, the chain will hit the chain stay when you stop pedaling. A high-tension rear derailleur or a clutch will solve this problem.
