I have an old Giant ATX 840 with 7 speed grip shift and Shimano Alvio derailers. The back wheel is shot and would like to replace with another wheel with Shimano 7 speed (14 - 34T) mega range cassette and some Shimano indexed combo shifters (7 speed Exage M system) from an old Trek 4000.
I have the Deore LX derailers from the Trek if this helps but top wheel on derailer is sus, and some Avid SD7's I'd like to use.
Are these components compatible?
Newbie needs help.
