I got some new wheels, with a SRAM 1070 cassette, 11-23. I had been using a SRAM 1050 11-25, and I could, and still can, shift into every gear.

On the new wheels, it WILL NOT shift into the 23, no matter what I do trying to adjust the derailer using the barrel adjuster, basically leaving me with a 9 speed 11-21.

Any suggestions?
