Agree about the shop.

Any link on the Cannondale specs using loctite? All I've ever seen from Cannondale is using loctite in an irregular shell - as in the linked instructions. I have two Cannondale bikes with BB30 and the bearings were not bonded when new and when replaced the shop mechanic was pretty adamant that using loctite was a bad idea. It may be necessary if there is a problem, but I'm not aware of anything saying it's required.
