Just upgraded my wifes old 21(7)spd MTB, to 27(9)speed.
The original BB was a 122mm axle. I've put an LX triple chainset on, with a 110mm UN73 BB.
Its just not right. The chainline is much further off board than it should be!!! If I revert to the 122mm axle, it will be even worse.
What am I doing wrong?
