What do you think of Shimano Dual Control?

I came across a pair of LX Dual Control levers on a bike at Performance yesterday. Before that I wondered if Shimano was going to move the STI concept from their road bikes to mountain. Here are the ones I tested it.


The new MTB Dual Control Lever sets a new standard for shifting ease. It let's you shift gears up or down regardless of your hand position on the handlebar. Internally, shifting is executed by the tried and true high precision indexing system found on the M950 series of XTR, featuring three sets of ball bearings that result in more precise shifts, a shorter lever stroke and a decrease in shifting effort.
Anyway the things felt really weird on the bike, probably similar to when I tried STI on a road bike for the first time. Maybe they were mounted at the wrong angle (too shallow, I like em pointed down a bit), but the thumb lever was hard to reach. The brake lever, which now functions as a shifter as well, felt real flimsy because it had a lot of vertical play. Pressing the brake lever down would shift one way, and pulling UP on the lever (how would you do this? from below?) shifts the other way. SOO weird.

Anybody here use this new system? Does it work better than the old? Did it take you a while to get used to it?

I never used them, but I'm assuming that tapping down on the brake lever drops to an easier climbing gear, and pushing the thumb takes you to a few more gear inches?

Lose the thumb lever. Just push the lever up and down.

Suitable and recommended on my XC bike. Works best with rapid-rise.

Wouldn't put it on a DH rig or similar.

I use and like tha exact same ones as you picture. Some don't but it's all I've used since getting into MTBing about 2 years ago. I think it's what you get use to. Recently changed from Low-Normal to High-Normal RD (LX to SLX) which made shifting backwards from what I was use to but it seems very normal now.

A friend of mine's bike had those on it. He LOVES them. I test rode it for a bit, and I just wasn't sure of it. I ride 2 fingered (I always have 2 fingers on the rear brake, a habit I picked up from my BMX bike that had only a rear brake and riding ATV's) and when hitting a really bumpy/ techy section I'm worried that I'd accidentally bump it down.


I guess you get used to it?

With single or two-fingers-over-the-lever-all-the-time-motocross-grip-style-of-riding (whew that was a mouthful), this system has the potential to cause havoc and untold accidental mis-shifts. Otherwise on less jarring terrain it should be fine, so it all depends on the type of riding you do.

The term MTB is so broad these days because there's so so many various ways to "do" mountain biking.

Also, on falls or crashes (think bent levers) there's a chance you could loose your shifting capability too. Not something I've seen or will likely ever see in the gravity side of the MTBiking family... just too impractical if not dangerous for that genre.

^ I never though of broken levers... that would suck.
Yea, They wouldn't work for me, Rode to many ATV's and BMX, got that 2 fingered brake lever grip embedded in my skull

I have them, and personally I like them. It did take some getting used to, as I like others mentioned here always rode with fingers on the brake levers. As a FYI, you can pick them up at backcountry.com right now with complete 203mm centerlock disc setup for $65 a wheel.

I kinda feel like saying this, but my friend and I just figured out that you can use the shifters with only your thumb, not only thumb and pointer finger.

I've had the XT version since 2004 [came stock on my Trek 8500], paired with a Rapid-Rise rear dérailleur. I recently picked up the new version with all the zippy adjustments for lever travel and such. Despite my abuse, these things have held up incredibly well. I've crashed many times, and have never had a problem with the lever. It's actually resistant to damage because of the design - the lever can move up or down AND in at the same time. I tend to cover the right lever with two fingers when I'm on the flats or descents, and I can't recall accidentally shifting. Even if I did, I'd be going to a harder gear, which would make me go faster, so it would be a good thing.

The dérailleur does the work for you when going to an easier gear. You just tap and it's done, very precisely. Shifting to a higher gear is almost as easy, since the chain "wants" to go to the smaller cog, and the lever gives you plenty of leverage [hence the name]. Shifting under load is not a problem. Braking - it just works, all the time, every time. At one point I thought I needed to bleed the brakes because they got soft, but it turned out that I had worn the pads right down to the metal after 3.5 seasons. $20 for new pads and it was like having new brakes again.

Overall, I'm a fan of the system because it works. It's not the "cool" system [push-push shifters are the shizzle, right? I remember the 80's too...], and I don't care that it's Shimano [I run Campy on my road bike and no Shimano on my SS rides]. It works for me, YMMV.

I have the LX version shown, and as previously stated it is designed for rapid rise RDs. The shifts are precise and clean. I found the setup very intuitive and I actually like the thumb lever for downshifts.

One of these days I'll get my hands around these for a proper test ride. They did feel weird in the shop though...

I've have/had most of the different MTB types. Deore XT thumb shifters, SRAM Grip shifters (got rid of them), XTR trigger shifters and XTR M960 Dual controls. I personally prefer the Dual controls by far.
Haven't tried the LX version, but the XTR is really solid and precise, but I too would recommend scrapping the thumb thingy. I just find the braking/shifting action the most intuitive. Also if I get lazy I can shift while on the bar ends

I have that exact version (Deore LX) on my C-Dale F300 that I use for Am and XC. Works great, no problems with them at all. Thumb shifter is no problem.

It is common for people to hate what they don't understand.

Oh, I understand them just fine, have used them and worked on them, I just think they suck (same for rapid rise).

My new Jamis dakar has XT dual control shifters. I like them in that shifting becomes mindless. Where-ever your hand extremity is..it can shift.

Is it me, or do the Shimano XT shifters (dual control) just plain look cheap?? Especially the silver version.
Hell, the LX series even looks more expensive......................My girlfriends Alivio on her Trek looks sharp.

This is Shimano's top teir mechanics... and it looks awful.

Different design team. Hey, the Japanese have penned numerous fugly products to their credit.

I guess light, quick, precise shifting doesn't count

I have light, quick, precise shifting, thanks, better than the DC's. Just don't like it when I have stick my fingers out and move the brake levers with extended fingers to get it...YMMV.

All I can think of is how expensive crashes have the potential to be now.

This very thing happened to me. I took a bad fall and broke my left LX dual control lever off. I wasn't able to shift, but I was still able to brake by pushing back on the body of the shifter. I was able to complete my ride, albeit much slower.

I have since replaced both with XT dual controls. They shift much better than the LX since they use bearings instead of the LX's bushings.

^ Cool.

Mountain bike component designers come from various backgrounds and we are all the better for it.

BMX influences ushered in the A-head stem, platform pedals, low slanted toptubes etc. Motocross influences brought about disc brakes, the modern "dog leg" MTB brake lever shape, knobby tires, full-suspension, thru-axles, riser bars and so forth. Road brought in the passion for weight reduction, butted frame tubes and spokes, cassettes and derailleurs, hollow quick release axles, amongst other things... including the DC levers.

We're pretty spoiled for choices, and it's all there for us to pick and choose for our various applications, to enjoy as we please. It's all good.
