I've been trying all afternoon to get my gears on my mountain bike,
The rear X9 mech went straight on, as did the cassette and cranks however I'm having some trouble with the front mech.
It's a Sram X9 top mount top pull
First issue was that the frame is too skinny for the clamp, this was resolved by wrapping a small bit of inner tube inside the clamp before positioning the mech where described, with the chain guide 3-4mm above the outer chain ring.
If the chain guide is positioned in the correct place then the chain scrapes on the chain guide (the horizontal part) when using the smallest chain ring
If I lower the mech down the seat tube slightly to compensate then the guide hits the largest chainring.
What am I doing wrong?
