    Scott Aspect Tour Bottom Bracket?

    Is there a way to know the measurements for a bottom bracket on a Aspect Tour 29er without pulling it out? I know its a Shimano BB UN-26, but thats it. Mine is making a awful creaking noise, so I want to replace it myself.

    Also what tools would I need, a crank puller and a BBT-22 tool?

    did you ever find out what size it is? I'm looking to upgrade and I'm not sure on size either.

    I emailed Scott direct and they gave me a size of 68 x 122.5

    Sorry yes, I did end up emailing them and that's the size I got. I ended up getting a hollowtech crankset though. Sadly it doesn't perform perfectly and drops the chain a lot.
