I always find that about a week after I get rid of something, I find a use for it.

I had a new cheap 7 speed chain with no guide ramp thingys (what are they called?) on the outer plates to protect the derailleurs from the rivets and some cheap alloy MTB pedals I bought and decided against for a road bike. Last weekend I got a free Mountain Bike and used them both to replace beat-up and worn-out parts.

I'll probably replace the chain again but it allowed me to get the bike up and running.
