I recently stripped my bike and rebuilt it, using a different front mech (2005 XT) as it did not need a clamp spacer like previous (2006 LX). After adding new cable, fitting mech with correct tolerances:
Low limits: Front small, rear big 2mm chain clearance from cage
High Limits: Front big, rear small <2mm clearance from cage
Cage position as close to front big cog without interference, slight bit of toe in.
Cable tension by hand then adjuster at shifter.
After playing with the tension for a bit the gears were shifting but i could never get an even balance of quick up and down shifts - it was one or the other or none at all. (Drove me mad )
The only thing I can think of is when I put the chain rings back on there is a particular config that i should have stuck too? is this the case or can they just be bolted back on in any way (the chain rings have different grooves and pins and different places).
