Got a 44T in the front and a 11-34T in the rear.
XT 04 cranks and XT 03 rear de regular length cage (I wanted non-rapid rise
).
XTR 04 front de (seems to be what has been recommeded to not hit the swingarm)
Currently have the chain length at 54 links (108 pins).
In the static position (bike unladen), everything looks fine....
But I noticed 2 things:
1. In the big chainring (44T), big cogset (34T), the swingarm will not be able to go through the full 5.5 inches of travel. The chain will simply not be long enough and will stop the swingarm about halfway through the travel. This I guess is due to 'chain length growth'.
I am afraid that if I happen to encounter a big enough hit in this gear, I might snap the chain.
Q1: What is the length of chain you guys are using? 54? 56?
2. I am not able to keep the bike in the big chainring, big cogset when riding. It will simply flip flop back and forth between the largest and second largest cogset. The shop mechanic explained that the chainline on the 5.5 was not optimal and that was causing this. (He had put in a spacer (2.5mm) on the BB otherwise the FD would not clear the seat tube in the granny gear).
Q2: What the size of the spacer you guys put in? or translated the spindle length?
PS: I am not blaming the mechanic, I think he's doing a decent job in the absense of a manual... I just want to get this sorted...
