Hi guys.
I have a question about bottom bracket size on my Scott aspect 950, i have the shimano bb-mt500 hollowtech ii, if you google it, it says 92mm width?
But on the bracket it says bc 1.37x24t , if i google that it says 68-73mm width.
Do i have standard 73mm?

Measure the width of your BB shell to determine the correct of bottom bracket you require.
You have a 68-73mm wide BSA bottom bracket. You can get any Shimano hollowtech 2 MTB 68-73mm BSA bottom bracket as a replacement. The 92mm you googled is for the BB-MT500-PA press fit. The BSA version is called BB-MT501. Either get that one or one that’s slightly more expensive but should also last longer.
This is the 73mm shimano Hollowtech II BB. The threads are a bit longer than the road 68mm cups. Otherwise they look very similar.
