Can't get into lowest gears - Rear Derailleur indexing?

Postby robocat » Tue Jan 15, 2013 09:55 am

Hi Guys,

I just fitted a new SRAM 7 rear derailleur and cable to my Boradman hardtail and I can't get into the two lowest gears. I used the limiter screws to get into the highest gears, but the low limiter and barrel have had little effect. When shifting from high to low I can hear a couple of clicks before the chain moves from high to low (9 to 8), so I assume this is the problem, but now idea how to fix this. :?

not shifting into the low gears is normally lack of tension in the cable.

Thanks guys - increased the tension, followed by Park guidance, but still can't get into the bottom two gears - I assume I have some problem with the deraillieur itselfs.

Unscrew both limits. Undo cable completely and push the mech with your hand to see if the top jockey makes it in line with each of the outer cogs.

Does it shift iinto next from highest gear on the first click of the shifter?
Does it then shift all the way to 3rd (3rd largest rear sprocket) correctly?
What EXACTLY happens when you try and shift into 2nd? (shifter feel, etc etc)
