|Slop in cranks (properly installed)||spincircles|

|I noticed some slop/play in my crankset. It's a campy chorus 10sp setup, a couple years old. I assumed it was a shot BB, but when I removed the cranks I found the BB to be in perfect working order. It seems to be the crankarm spindle interface (or lack thereof). No matter how well I torque the bolts the cranks have a little play. Any ideas, do I need a new crankset? Thanks...|

|I take it back. It could be the BB. When I had the cranks off though I couldn't feel any spindle play. So I'm not sure which is the problem.|

|Put both crank arms back on and torque the bolts to spec. With the bike in a stand, grab both crank arms and rock them side to side... if they both move it's your bottom bracket... if just one moves, it's your crank. Take a look at the square of your crank arm.... if it shows any wear, it's wallowed out and you need a new one.
If you aren't sure what to look for, I suggest you take it to a shop and pay someone to check it out for you. Chorus stuff is too nice to mess up because the bolts weren't tightened down. And don't worry, there is no pride lost in paying someone to take a look at your bike and possibly saving your cranks for you (and a couple hundred bucks too..) so don't be apprehensive about taking it to a shop.
