SRAM X7 rear derailleur indexing troubles

rayman.h

Hi,

Just got a new used bike, which the seller said the gears needed adjusting so I thought it would be a quick indexing, as I have done before.

However I tried it (undoing the anchor bolt, adjusting the limits etc. I've done it before)and found the low limit wouldn't screw in enough to bring the derailleur in. Another thing was that is was shifting from 1-5 well but would skip badly from then on.

I took the derailleur off (which looks fine) and found the hanger was bent so I will replace that and I hope that will solve it. The frame looks straight as well.

Another issue was when in the highest (smallest) cog and the smallest chain ring the derailluer was very curled up, so much so that the returning chain was millimetres away from the chain coming from the first derailleur wheel. And this was with the B screw adjusted correctly. Chain is standard length as well. Here's a pic:

not an issue just gears you should not be using,

That's what I thought, obviously if I'm in the smallest chain ring then I should be using the larger cogs anyway.

even helps with chain length too

that mech does not look like a long cage either.
