Thanks for all the replies. I ordered the park tool I am removing the bb because I purchased a new 105 groupset for my Ironman and I'll be replacing the bb with the new one. So yes I will only use the tool once but it cost me $10 less than what the LBS charges to remove a bb. Also don't have a 15 crescent so I'd have to buy something. Really wish I had a place to install a vise grip because it seems like it comes in handy working on bikes.
