Removing the idiot disc(7 posts)

I got my new bike built yesterday (specialized allez comp 18(SWEET)) and even though I was there watching it get built, I spaced on the idiot disc. So it's still on there. Is there a way to remove it without taking the rear cassette off? Should I just break it? Why are those things there in the first place?

I've taken a pair of tin snips and cut it into six or eight "slices" like you'd cut a pizza, and then wiggled the pieces until they broke off. Be careful not scratch or cut a spoke.

Garden pruning shears work, too, if you don't have tin snips.

The best way to do it is to remove your cassette. Go to you LBS and buy a chain whip and cassette tool. You'll need this sooner or later anyway -- comes in handy when you get into swapping cassettes for varying terrian.

If you're too lazy to do this, then just break it off with a screw driver. It should break pretty easily.

What's its purpose? Its supposed to protect the spokes on your wheel from the chain if the derailer is not adjusted correctly and jams the chain into your wheel. It is a completely useless device if you have your RD adjusted properly.

...Keep idiots from ripping the rear deraileur off their frame after they do their own maintenance.

It serves little purpose
i if
your bike it set up correctly. For some people that is a big
b "IF".
Agree, but consider this:Spoke Wrench

If you aren't mechanically adept enough to remove your own cassette, which is NOT a big deal, maybe you're the kind of person should keep the spoke protector.
