Roll on Spring Time!
I havent really focused enough on getting chainlines setup correctly untill I picked up a Corsair Maelstrom. This bike really seems to want a perfect chainline to keep the idler pulley happy. Last night I stripped the drive chain down again, getting sick of this routine, to remove a 2mm spacer from the drive side which meant I had to add to the non drive side. This has helped alot but I may go single ring up front to really get the best performance and it seems like I would need to take the last 2mm spacer out to allow the full range of rear casette. It seems nuts that I would then have to run all three spacers on the non drive side which would also feel crap on the pedals, so I was wondering if I could cut /modify the plastic sleeve between the BB cups? I noticed there are 3 rings on the sleeve and I was wondering what these are for and for that matter what is the sleeve actualy doing in there? Sorry for the noob question but in the last 4 years of working on my bike I have never had to look seriously into this.
