Clean your bars.

In the world of remote saddle droppers and shock lock-outs, it's important to reduce the rampant over-population of handlebars. Shimano's answer to this dilemma is the direct-mount, to XT and XTR levers, Deore XT SL-M780 I-Spec B Shifters. It's the same shifter we've come to love, and is configured to work in conjunction with Dyna-Sys rear derailleurs and 10-speed cassette.

They also have the 2-Way Release (Push/Pull option) for the small trigger, so you can operate them with either the pointer or hitcher. Another nice touch is the option of making a shift across multiple cogs with one throw of the lever -- up or down. The Shimano Deore XT SL-M780 I-Spec B Shifters work with three chainrings up front and ten cogs in back.

  • Clamps to brake lever
  • 3x10 drivetrains
  • 2-way release

Awesome Shifting

  • Familiarity: I've put it through the wringer

These are super durable and offer smooth and crisp shifting. Pair these with your Shimano levers to clean up your cockpit.

XT SL-M780 shifters

  • Familiarity: I've put it through the wringer

Shifting them a little over 2000 miles and enjoy the easy shifting. Ridden through the muck, rain and shine with no change in the performance.

Shifts Well

Shimano XT shifters offer excellent performance and durability. Compared to the XTR shifters they are quite close in performance but the XTR have just a little extra crispness when shifting. The XTs still operate very smoothly and provide solid shifts. The thumb lever is smooth and would be nice to have dimples in it to help give better tactile feel when shifting. Overall the XT shifters are outstanding shifters and will work hard for many years. The I-Spec helps clean up bar space and mates nicely with Shimano levers that are compatible.

Unanswered Question

Does the shifter come with the necessary mounting nut to connect with the older m785 i-spec A brake levers?

These things shift and feel great. There is a satisfying click feel with each shift. Compared to Sram shifters, the trigger to shift down the cassette is not as ergonomic, but I got used to it.

Be cautious with the ispec mounts because in order to rotate the shifters around the bar, you must also rotate the brakes as it is no longer independent. moving the shifters horizontally along the bar is independent, but you're still limited. Unless you have really extreme positions, this shouldn't be an issue. I have no problems with the limits of the adjustments, but some may, so be cautious. Also, if you want to convert these to the bar mounts, Shimano does not sell them, so you're stuck trying to find someone who will sell them to you who have converted over to ispec from their regular bar mounts.

I got these to clean up my bars and this does this perfectly.

Do these come with cables and housing?

Do these come with cables and housing?

typically shifters come with cables installed...supply your own housing

Actually, they did come with shimano cable housing and the housing ends, as well as cables.

I plan on running a Wolf Tooth single ring upfront, will these work?

Best Answer

As long as you are using a Shimano rear derailleur in the rear.

Are these the right shifters to fit with...

Are these the right shifters to fit with the new 785-B brake levers

Yes, these are the B-Spec version of the XT shifters and will work M-785-B series brakes. brett@competitivecyclist.com
