My and I'm already looking for help. Go figure.
I have a square-type Shimano bottom-bracket axle and cranks. I have removed the cranks, greased the axle, (tried the cranks un-greased too) and then put them back on only to have a clunk type sound emanate from the BB at the same place while cranking. When I return home I find the bolt holding the cranks on have either loosened or the cranks have moved further in on the axle. I have used a torque wrench set to 28 lbs-ft each time but after a 50 minute ride I find I have to re-tighten the bolts.
Question: What should the torque be for these bolts and am I missing something obvious to you'all?
Thanks!
