Took the old BB out my GU today to put my newer trialtech one in.
I done it as normal and put the driveside in first, but then I couldn't get the non ds cup in? I looked in the hole and the BB axle bearings did not look centre?!
I tried it again and the same happened.
I then tried this...
Screwed the non ds cup in about halfway and then put the ds in, the last few turns on the ds were ridcoulousy tight but it now works. The only problem is the axle doesn't appear to spin easily I undone the non ds a bit and it was still the same. Any help?
The BB is quite new and is the non lite trialtech Isis version.
