Default Re: **** Idler Wheel Failed Again, Need Help****

You have two choices if you dont want to go with the shifter kit.

You can use a deraillier set up to act as an idler - this will mean you threading the chain through the deraillier and the advantage with this is that it literally cannot come out or off - you just have to make sure its set up and adjusted correctly. Additionally it also provides some sprung play into the drivetrain.

The second choice is to drop any idler altogether. You will need to shorten the chain so there is permanant inbuilt light tension in the drive chain.

Finally think about the way you ride - opening the throttle wide open or even having the throttle someway open and dropping the clutch is a surefire way of inducing chain-snap and this is usually what leads to the chain coming off.

You might also try running the chain on the old idler, but putting it on so that the chain runs across the bottom of the idler wheel with the mounting bar on the spokes side of the chain - this will hopefully block the chain from both chainsnap and other issues.
