I bought a new deraluier and it wont shift to the first aka largest aka closest to the wheel / dropouts gear its about two inches too high but I've. So it (the deraulier) knocks into the largest easiest cog. I've fiddled with the B screw already tightening it all the way in. But the deraulier jockey wheel keeps rubbing against the first gear cog on the cassette.

The smallest aka High Limit screw is already correctly adjusted I believe and I just had the deraliuer and hanger replaced so they are straight.

As the picture below shows (the deraliuer is too high, not enough vertical distance between the hanger/dropouts and deraliuer jockey wheels.

The gears are currently on (1/3 in front) and (2/7 in back) the largest cog easiest gear to ride in is 1, which I can't switch to.

I have a 7-8 speed SHIMANO ACERA RD-M360-SGS for $30 AUS http://www.cyclingdeal.com.au/buy/shimano-acera-rd-m360-7-8-speed-rear-derailleur/RD-M360
