Let’s say you’re increase a gravel bike and have a wheel that you simply wish to use that sports activities a rear hub with a Shimano HG cassette physique. Let’s say you even have an 11-46t XT cassette, and a Shimano MTB rear derailleur, like an XT or XTR, you’d like to make use of. You need your new gravel bike to have a variety, like your MTB. You additionally wish to use your cable-actuated disc brakes with the brand new construct.

That’s proper, no rear derailleur cage swap, longer “b” screw, Goat Hyperlink, or must rebuild the shifter with a mod equipment to get the correct amount of cable pull.
You possibly can cease typing… I do know there are fairly a couple of choices on the market to drag off a practical 1x mullet drivetrain on your gravel bike. However, a number of the brake/shifter combo levers are paired with hydraulic brake calipers, are costly, digital, and/or 12-speed.
If in case you have the Shimano MTB elements I discussed above, you may construct an important mullet drive prepare on your gravel bike for nicely below $100. Not many different choices (if any) will allow you to try this.
I’ve obtained near 800 miles on these shifters they usually’ve labored flawlessly. There have been some mis-shifts, each every now and then, however we’ll contact on why that occurred slightly later within the overview.
The Sensah SRX Professional
The Sensah shifters shift utilizing kind of a hybrid Shimano/SRAM fashion with a “double faucet” actuation however with a single lever.
The levers themselves have attain changes to get them to the specified distance from the bars for the rider. That’s a pleasant contact for a shift/brake lever at this value level.
The shifters supply a pleasant high-quality, hearty, and constructive “click on” when shifting up or down the cassette. They provide the means to push the lever all the way in which to the left and shift three gears up the cassette in a single swoop. After which the traditional single click on at a time to return again down the cassette.
Sensah SRX Professional Set up
I obtained the Sensah SRX Professional levers from Velo Orange, who contributed them to my Masi Incanto Dream Construct mission. Once I constructed my Incanto, I needed to run an XTR rear derailleur and my Paul Klampers with drop bar shift/brake levers. And I needed it to be a clear set up, sans little doohickies to make it work proper.
The set up went fairly easily. I Didn’t notably love the shifter’s routing for both the brake or shift cable housing. Due to the cable-actuated brakes, I used to be operating stiff, compressionless cable housing.
Getting the shift housing to make that first drop popping out of the shifter to the bar and dropping to the entrance, left facet to go beneath the bar, was tough. It required some stiff tape to carry it in place earlier than wrapping the bar.
You possibly can see within the image above (high, left) that the shift housing continues to be not seated within the offered notch all the way in which. The opposite possibility would have most likely routed simpler, however put the housing to the surface proper of the bar, and that appeared, on the time, a much less fascinating route.
600+ Miles with the Sensah SRX Professional
This was my first set of brake/shift levers that I’ve used that shift with one lever, so, I suffered a little bit of a studying curve with that.
Total the shifters shifted flawlessly. Once I say flawlessly, I imply with out one problem for over 600 miles of “not-so-kind shifting”. It was a constructive shift to the proper gear each time. The “mis-shifts” I had weren’t about lacking gears, however had been extra like unintended shifts, “person error” generally.
There’s an automated “brake lockout” in-built to the fitting lever that helps forestall the unintended shift whereas the lever is definitely pulled again right into a braking place. However the motion is so mild, that generally I’d unintentionally make it downshift when merely reaching for the brake.
What About Egonomics?
The ergonomics of the SRX Professional shifters weren’t fairly on par with the opposite large manufacturers. It wasn’t a deal breaker for me however wasn’t fairly the identical both. Plus, with the sunshine motion and long-ish kind throw of the lever when shifting up the cassette, it took a bit to get used to. It felt cumbersome at instances. And the sunshine motion didn’t do nicely for me when braking on a technical descent. I’d be blissfully bopping down a path, within the drops, and increase, mis-shift. This occurred extra typically than I’d prefer to admit.
Even after I felt I had realized the idiosyncrasies of the shifters, practically each time whereas within the drops and the path obtained tough, or I needed to shortly seize a handful of brake, the mis-shift would occur. It was nothing catastrophic, or one thing that I couldn’t tolerate, only a bit annoying.
One thing else bugged me slightly greater than the unintended shifts. Once more, due to the combo of sunshine motion and the longer throw of the lever, I discovered when braking whereas within the drops, with one gloved finger on the lever, the fitting lever would wish to slip out of my grip, to the left, leaving me reaching additional for the brakes. That was uncomfortable on multiple event, to not point out a bit panicky feeling on a couple of different events.
