A friend recently bent the front foot peg, just wondering the best way to straighten it out.  Do they come apart?  We have it off the bike, but can't really see anything else to do.  Should I just use the biggest hammer possible?  Thanks!

Thanks Greg, that is sort of the answer I was looking for.  I have given it a couple of half hearted attempts to smoosh the rubber, but they were basically as I was sitting around thinking when I was supposed to be working.  The guy is not in too much of a hurry, the peg got bent but his leg got broke.  

I think the pegs are kinda like a box. 2 rails, kinda wimpy. Hard to straighten. Need 2 hammers. Put it on the bike, lay the heavy hammer against the peg on the part of the peg that doesnt need "moved" to be in its proper place, then, slowly start tapping the end in the direction it needs to go,the hammer nearest the bike should slowly come away from the bike. Dont try to fix it on one or 2 passes. Take your time,

Thats the first thing learned doing body work. That & "backing up" your work,
One hammer against the piece, the other tapping away. Its like putting a cheater on it. THe backup is the fulcrum.
