Shimano Zee SL-M640 10 Speed Right Shift Lever

For $45 it is a beast. Went to my local bike store and it costs $100. It is perfect for what I do(mostly dirt jumping). It is pretty much the same as the XT but way cheaper. It works great with my XTR derailleur. Got the last one I could find on 15 different websites and so glad I found it. Definitely worth my money.

Very happy with the performance of this sturdy little shifter. Have over a year of use, a few crashes and a lot of hard riding, mostly enduro/trail. Coupled with the zee derailleur which i love for its reliability and quiet chain retention/zero chain slap. Obviously its not top of the line but definitely a worthy 10spd setup.

In the past year or 2 with these on 2 of my bikes, I've had to replace both due to premature failure. Overall I'd say they work well while functioning, but the build quality seems a bit lacking - the last one just all of a sudden stopped shifting properly and then the bottom fell off, with no hard riding at all. That said, they're half the price of a Saint and 10sp options are getting thin on the ground, hence the like for like replacement.

this was to replace an slx shifter that had worn out. There doesn't seem to be a lot of options any more for 10 speed shifters any more and i was due to sell the bike so thought this would do.
The shifting after the SLX feels very stiff, so while it works as advertised i wouldn't recommend it.

Perfect for the price, no failure of any part of the shifter. It doesn't feel as snappy as a XT shifter but still works great.
