The shifter works well as it should. It works a little stiffer than I would like. Replaced it with Shimano Altus SL-M2010-R 9 Speed Rapidfire Plus Shifter. This shifter is much more ergonomic and finger trigger and thumb shifter is easier to shift.
Ordered a few sets of these because I had been reading about them... These are super nice! Well made, look great, all metal, and snappy "click"! And the price is so reasonable! Get them before they get popular and disappear!!!
