This model is for mating Shimano shifters with SRAM 1:1 derailleurs or SRAM non-road shifters with Shimano derailleurs.

It will also let you run Shimano 10 speed road STI with Shimano MTN 10 Dyna-Sys derailleurs and Shimano or SRAM cassettes.

The ShiftMate Straight is an inline shifting interface device for mating different bicycle shifting components. Using a ratio changing pulley, the ShiftMate Straight adapts different component brands and models to make the proper correction in the amount of cable pull needed for perfect shifting.

- CNC machined.
- Sealed ball bearing.
- Hard Nickel plating.
- Ideal for straight cable run mounting or mounting at cable stop locations.

*Except Shimano Tiagra 4700 10 speed shifters and rear derailleur

Proseasy to install
Excellent service after I asked some questions about a component. Fast detailed reply enabled me to buy the part I needed, to get my bike rideable again.
Fast delivery good instructions and easy to install. The part enabled me to use Shimano gears with a Sram derailleur. Perfect setup for steep hills. Excellent quiet gear changes. Top piece of engineering.

Will use Sjscycles again.

Proswell made, in-line fitting
I built up a Monster CXer based on a 10sp MTB. The Jtek 6 allowed me to run Ultegra 10sp STI shifters with the existing MTB rear mech and cassette. The inline mounting allowed it to be mounted on the chainstay & away from interference by the mech. Works perfectly

ProsVery Easy to Setup, Follow Instructions, Adjust Cable Tension When Needed
Very easy to setup and install as per the instructions, followed step by step, I used the inline version and mounted the shiftmate up toward the barrel adjuster by the fork tube, then routed the shift cable in the normal way I used a brand new cable and knew I had to stretch the cable before shifting would work correctly, Once everything settled in place "shifting is awesome"!! Using it on my Road Bike with a shimano dyna-sys 10s MTB RD 11-40 cassette talk about low gearing triple crankset up front "No Hill to Steep"!

ConsNot easy to identify what type of agent I have in hand.
ProsAll of these have worked perfectly
I have a few of these now and I am not sure how to differentiate between the different models.
SJS Customer Service:
Thanks for the feedback. We are currently (2016) using unlabelled stock produced by Jtek in the USA, however we will note this for future UK managed production runs.
It Really Does Work

ConsQuite expensive, no barrel adjuster
ProsEasy to set up, good quality
I'd tried a Lindarets Tanpan SH10 (1st generation) to make a 10 speed 105 shifter work with a 10 speed Deore clutch mech, but it was a complete failure due to a product flaw.

I was therefore a little hesitant to try the Jtek Shiftmate, thinking that all ratio-altering devices may be somewhat temperamental. I was wrong. The Jtek Shiftmate 6 was easy to set up, and worked straight away on the stand and on several off-road rides since. I mounted the device close to the handlebar to keep it away from the muck.

It would have been nice if the housing was curved like some of the other Shiftmate models, but the only niggle I have is that it has no barrel adjuster, so had to use a separate in-line adjuster.

What About The Tiagra 4700?
12 Mar 2017
It says it's not compatible with the Tiagra 4700 10-speed shifters, but I have these and am looking to change the rear gearing to a 40 tooth cassette and new derailleur. Is there a shiftmate that would work? Thanks

Unfortunately there is not a Shiftmate that will work at all with the Tiagra 4700 shifters or derailleur as they do not use equal jumps between the gears. The shifter pulls a different amount of cable between gears 1 and 2 as it does between gears 2 and 3 unlike the rest of Shimano's 10spd line up that has even jumps across the board.

Is There Any Sihftmate That Works Shimano 11S Road Sifter And Sram Rival? 1 X-Horizon? Rear Derailleur ?

As the Rival 1 derailleurs still use the same cable pull as the 11spd Sram road groupsets the Shiftmate you need is the number 4.

Hello, Is This Shiftmate Compatible With A Shimano Deore Xt Rd-T780 Rear Derailleur? Thanks

SHIFTER: Shimano 10 speed road
DERAILLEUR: deore xt rd-t780 rear derailleur
Hi, Yes this is the correct Shiftmate for you.
