Bottom Bracket Replacement on Trek Soho S
I'm wondering if any of you mechanics have any experience dealing with the Trek Soho S and more specifically their bottom bracket set-ups. I must replace the cranks and due to the change the BB must be replaced as well ( I think ). I can't find anywhere the type of information I need to make this work myself. So I'm here asking for your help.
Would appreciate any appropriate information for replacing the Cranks/BB on a Trek Soho S.
My problem in further detail
( for those interested )
I have a Trek Soho S
which I am planning to sell. Before I can sell it though I know some parts need to be replaced. One of these being the crank set. I accidentally stripped one of the crank arms when doing a routine maintenance. My solution at the time was to thread the pedal through the opposite side of the crank arm and re-thread the crank in that way. It has worked well and I haven't had any problems but I don't feel comfortable selling the bike with those cranks on it.
I have been looking at new cranksets and have thought to buy the SRAM S100 1.1.
Mainly because SRAM is kept in high value here, the price is reasonable enough, I can get it from reliable dealer quickly. It's recommended that the S100 be used with a PowerSpline BB which comes in a variety of sizes. This is as far as I have gotten....
I have no idea what size bb I need and I can't find the information anywhere short of pulling the cranks off myself and taking the BB out and measuring it. If I have to do that, I can but it's going to have to wait till the weekend and I was hoping to order the parts before the weekend.
Does any one have any experience with this job on the Soho S? Any help you could throw my way would be appreciated. If I have left something important out, let me know and hopefully I have that information.
One other thing I was emailing with one of the mechanics from the shop I bought the bike from and the information which they knew was.
It's british threaded
the BB shell is either 68 mm or 73 mm
and nothing said of the axle's length
