The Shimano Deore SL-M590 9spd Shift Lever set offers Shimano's legendary shifting technology in an affordable and attractive package. The Deore SL-M590 is compatible with almost any Shimano mountain derailleur, and offers crisp, precise shifts every time. This newly-redesigned shifter offers an updated and improved 2-way release mechanism.
Right in the middle of the field as far as material and precision but not at all lacking in shift quality. With much of the future moving toward 10 speed these are a great option to keep your older ride up and running without sacrificing on shift quality. We highly recommend these.
