ha ha ha ha ha ha ha!!!!!!!
dont tell anyone but i really have been a f**wit!
i didnt notice the 2 screws underneath the bb shell 🙂
so there i was thinking i was loosening it by inserting an allen key into the sides, when really all i was doing was spinning the whole thing. and then trying to tighten it using the same allen holes when it was in position, instead of tightening it underneath. what a f**in donut.
still………if youve never seen one before 🙂 technology eh 🙂
btw, am i right in assuming that i WILL have tightened it sufficiently by just doing up the bottom 2 screws? when its all loose, the bb shell will slide from side to side too, so its proper loose in there. is that sposed to happen to try and get a perfect chainline or something?
i dont really want to start swingiing on those bottom 2 screws to make sure its tight in case i strip or bust them. it just feels like it should be done tighter to stop the whole thing moving when grinding away on the cranks. theres nowt to locate them in is there?
cheers
