Max sprocket size.. rear mech question ..

[Sithlord]

Hi guys,,

Anyone know if a rear mech that is specced for max 28,, will take up enough chain for 33 t? specifically 29t front and 33 rear.. ? , or am I stuck with a long cage. ?

changed shifters and mechs on my daughters islabike the other week, and an xt short cage (specced for 2 seemed to catch on the 32 big sprocket and wouldn't physically shift over.... so I also had to suck it up and put a long cage on

hope this helps

John

Hmmm was thinking as much,, I assume that you had adjusted the 'b' tension screw to its limit.. ?

 

[john the sparky]

yeah, wound adjusters right off just to be sure....wasn't that it stopped trying to move, more that the top jockey and big sprocket seemed to catch
