Rear mech hitting hanger

Postby 3Bears » Fri Oct 05, 2012 09:43 am

I'm slowly trying to get a Carrera Gryphon I got cheap on ebay fixed up.

I'm using a spare 2012 Sram x7 rear mech, it bolts to the hanger fine, but the part of the mech that houses the b screw hits the hanger. To clear it I have to wind the b screw all the way in which leaves a huge chain gap. I'll try and grab some pictures and update the thread.

Anyone had this before?

so when setting up the mech what is the clearance between the top jockey wheel and the small cog?

with chain fitted.

With the b screw all the way out (so it's as close as possible), it's a couple of cm's out at least - not even close. Before, I've just let it hit it, and then back out until it clears it, but with this bike I can't get it anywhere near the cog. This is with a long cage x7 with a 11-32 cassette with a 22/32/44 triple up front.

I'm going to go take a picture now.
