Hi guys,
I’m in the process of building a bike for the mrs, using various used bits sourced online. I’m almost there but having a problem with the rear mech top jockey wheel touching the biggest cassette ring when on the smallest front chainring… I’m trying to work out if I’ve bought some incompatible bits, here is what I have:
I’ve tightened the Higher-Adjuster screw as per (as tight as it will go) will a longer screw help? :
but the rear mech jockey wheels still touches the casette but only when the chain is on the smallest front chainring…. is it the chainrings/crankset to blame?
Rear mechs have a maximum top sprocket size. For those giant mega-range ones you have to have a certain mech with a really big jockey wheel for instance.
I’ve tightened the Higher-Adjuster screw
That’s the b-tension adjuster but yes it is what needs tightening. A longer screw won’t work as the angles get messed up (trust me).
I have 11-34 on both bikes, one with SLX 22/3?/44 tripple and longer cage, the other with SLX 22/36 double and short cage. Neither are a problem, so I doubt that this is what the OP is experiencing.
is the chain the right length? big chainring to big sprocket NOT thru the mech and add two links
I will check this tonight when I get in, but can you buy chain extension links? for these poplock style SRAM chains? (sorry this is the first one I’ve used)
