SRAM’s specifications require the high pulley’s inner edge to line up with the high cog’s outer edge, this putting the pulley a little closer to the frame than it would with shimano. The low pulley is normal- centered on the low cog. Adjustment from those positions compensates for misaligned derailluer hangers. OK. I’m bored!

I get good results with setting the B-tension as high as possible without the guide pulley getting so close to the largest cog that it “flutters” as the chain rotates.

On my two bikes, this means two things:

1. The MTB commuter with the 12-23 cassette and a Deore der gets the tension set as high as possible. This der was meant to be used with a larger cogset.

2. The road bike with the 12-32 mtn cassette and the medium cage Sora der gets the tension set as low as possible since 32T exceeds the intended Sora design limit by 5T. It still flutters a little.

Your b screw doesn’t have to do with fine adjustment, that has to do with your derailleur and how far it sticks off your cassette. I will explain this more in a posts next week, but the B screw just “lifts” your derailleur away from the last cog, so that your pulley’s aren’t rubbing the cogs.

If you are having shifting issues only in your middle gears I would check out your derailleur hanger for alignment. http://bluecollarmtb.com/2007/08/26/hanger-alignment/

Another thing to check is if your cables are well lubed, and pull through the housing with no kinks or hold ups. But it honestly sounds like your hanger or derailleur are slightly bent.

I have no problem with the limit screws, but I just can get the adjustment correct with the B screw or would it be the adjuster barrel?

shifting down is fine, hesitates, double shifts, and has trouble finding the gear in the middle gears, in addition, I have adjusted it so much my B screw is 90% stripped.
