ConsNone

ProsQuality shifting with wide ratios.

Used this to mate a Shimano 105 R7000 drop bar shifter to an XT M7000 rear mech. I now have a compact 105 50/34 crankset mated to an 11 speed 11-40 cassette. Trimmed to outer cable to give a neat install. Shifts as if Shimano designed it.

Pretty handy

Allowed me to go 1x without having to replace levers, using with xt mech and sram 10-42 cassette. Setup and shifting are great.

I read about this product in a few places where riders were gearing a 1x11 for cyclocross with mountain bike cassettes, e.g. Dirty Kanza. I bought it and it was easy to install, and worked flawlessly once the cable was tight! I have been riding in rain and dirt all week and no adjustments or issues...I matched an Ultegra road shifter with SRAM 11-speed derailleur. The cassette is an 11-speed Shimano 11-42T MTB cassette.

It Works As Intended

Now that I have had the widget on the bike for a while, it is clear it works well, as intended. Cable action remains quite light, unlike the main competitor. A bit pricey!

Works Well

Consnot sure if it handles riding on muddy roads...

Prosworks great on sealed roads

SJS sent the item with no delay. The ShiftMate works great. Using 11sp 11-40 Shimano cassette on the road because I aways need more gears :)
What can I say. I bought another one from SJS for my other Audax bike.

Can I use this to run shimano 11 speed Road shifters with XT front mech please

SJS Customer Service:

Hi,

this part is designed to be fitted to a rear derailleur so wouldn't be suitable for what you are wanting to achieve.

Thanks.

By jason hill

I have used this on the rear of my bike and works perfectly 5800 shifters and xt rear Mech.
But I'm of on a tour soon and thinking of an mtb double on the front.
Will I again need one of these to correct ratios between 5800 f shifter and xt fmech

Tiagra 4700?

By Greg

25 Oct 2018

As 4700 has the same cable pull as 11-speed Shimano components, would the 8a work with 4700 ×10 shifters, a x11 XTR M7000 mech, and a Shimano x10 11-42 cassette?

SJS Customer Service:

Hi there,

It does not look as though we have a shiftmate that will allow this combination im afraid.

Thanks.

Shiftmate 8 Vs 8a

By Callum

14 Mar 2018

What’s the difference or benefit of the Shiftmate 8a over the 8? I’m currently using the 8 to convert 11 speed STI (ultergra) to 11 speed XT 11-40 cassette. It works ok but regularly needs cable retensioned and wondered whether the more “fixed” configuration of the 8a plus barrel adjuster makes this a more stable set-up?

SJS Customer Service:

Hi,

Both options work well, it really depends on the bike itself as to which will work better. As you note, the 8a has an integrated barrel adjuster and sits direct into the top of the derailleur.

Thanks

Do I need to purchase cables to install this item?

By Lee

23 Oct 2017

SJS Customer Service:

Hello,

You should be able to use the cable that is already going from the shifters to the derailleur, given that it is long enough t thread through the shiftmate.

Thanks.
