[Closed] Derailleur cage fouling on biggest sprocket.

Got a bit of an issue with derailleur cages catching on the largest sprocket and jamming up or failing to shift back up.

Shifting into low gears is fine but then trying to shift from largest sprocket to next one down the inner side of the cage jams on the large sprocket and stops the derailleur shifting.

11-34 cassette. Chain length measured and derailleur set up according to SRAM instructions. Happens with both a long and short cage derailleur.

Any ideas?

Pic would be good - but is it just a case of adjusting the 'limit' screw on the derailleur? (i.e. Not the indexing screws, the other one)

EDIT: Too slow - as TJ says.

Already tried a range of adjustments on the B screw with pretty much the same result.

No pics at minute sorry - am at work.
