Shimano M640 Zee Shift Lever

Zee is Shimano’s new line of Gravity-specific components, designed and priced for those of us who do not have multi-million dollar sponsors. Specifically designed as a rear-only lever for 1x10 drivetrains, the M640 Zee shifter features crisp, consistent Dyna-Sys shifts and 2-way release. The Zee shifter's ergonomics make for an extremely comfortable, intuitive setup for the best performance when ascending or descending. The lever body is built for hard wear and tough usage, to continue working even after impact. Paired up with a Zee or Saint rear derailleur, you will be equipped to tackle any trail, no matter how gnarly.

  • Dyna-Sys 10-speed shift lever, rear only (1x10 specific)
  • Rapid Fire Plus
  • 2-way release (upshifts actuate with thumb or index finger)
  • Textured Shifter Levers
  • Linear Shift Effort
  • Shimano Shift cable included

      Comments about Shimano M640 Zee Shift Lever:

      I switched up from a 3X9 to a 1X10 and went with a Zee shifter/derailleur combo. It's definitely an improvement with the OneUp 40t cog.

      The Zee shifter does what it was meant to do. It's nothing blingy, but so far it feels like a solid combo paired with my Zee rear derailleur.

        Comments about Shimano M640 Zee Shift Lever:

        I was piecing together a bike and decided to go with a 1X10 drivetrain and only needed the rear shifter. This shifter installed easily and came with the cable but no housing. Positioning wise, it's about 3/4 of an inch to the left of my brake lever putting the triggers right where they need to be. The shifting is quick and positive and I really like being able to give it a big push with my thumb to downshift three gears at a time or a quick push to downshift one gear. The index trigger upshifts quickly and the levers feel fine to me. Great deal.

          this shifter works really well with the zee derailleur and is great on my 1x10 setup. it was kind of a pain in the butt to get it tuned the first time, but my bike mechanic finally got it dialled in. it has shifted clean ever since, (~500 miles or so) i love the simplified zee drivetrain. and it is an awesome price for the quality

                Awesome price and comes with housing. The lever is pretty long and grippy. The whole package feels and looks and is plastic. It's not crisp shifting at all, but I guess that doesn't really matter.

                    Kind of bulky on my handlebars but I haven't had a single problem with it. Love that you can shift 2 gears with a single extended trigger push. Have it set up on a trail 29er with a 1x10 drivetrain.
