Sounds a little like Shimano and the front mech but there are tips for it.
Might work on sram as well. set the low limit screw in the small ring and the 7th/8th sprocket.
Set cable tension.
Then shift to the 10th/11th (biggest).
then set the low limit screw again. It backs off and takes up the slack in the cable.
Then you only need to use the barrel adjuster (if you have one) for fine tuning.
Works pretty well to get the required tension in the cable.
What kind of rack? I've a Minoura Gamoh which came with QR plates. I drilled them out to fit a solid axle, but they they wouldn't fit over the lawyer lips on the fork. Suspect you'd have the same problem with other mounts :(
