I've just swapped my frame and rear wheel for a because simple and profile hub. The chain line is way out. the BB is a trial tech race, try all cranks (160mm) and obviously profile rear hub with 12t sprocket.
The chain pulls out at the BB end, I've taken the BB spacer out and the little washer in between the BB and crank, which makes it slightly better, but still not right.
What do?
Also the hub makes a kind of creak when putting any power into the pedals, is this chain line or a buggered hub? The hub has recently been serviced apparently.
