I was swapping around cranks this weekend and discovered that my 10 month old crank bros. cobalt BB is spinning very roughly. No play in the spindle, but nothing close to the smooth spin that it had when new (and nothing like the old square tapers that I'm used to). I had expected to get alot more life out of this one, but I guess no such luck. So I guess my question is, is this normal "wear and tear" or is it something that I can expect CB to warrant. I really don't want to give up on ISIS since I really like the race face compact cranks I've been using.
