Jteck Shiftmate Compatibility
By

Hi
I currently run a 6800 Ultegra road set up with a short cage Ultegra derr. Can I use the existing shifters, with a Lindarets road link to drop the rear derr lower, the existing Ultegra rear mech and a MOUNTAIN 11/42 cassette? Will a Tech shift mate be needed and if so will it work with the road rear mech this trimming it allowing for the different cassette cog spacing?

I'm trying to get the lowest inches down towards 20 inches without resorting to a Deore chainset with the uncomfortably wider Q factor.

Thanks
Hi,

The idea behind the road link is that you can keep your existing drivetrain components and just fit a wider ratio cassette. The Shiftmate 8 is designed to allow you to fit a MTB 11spd rear derailleur (which was designed with a wide ratio cassette in mind so will shift better) and use it with your Ultegra 6800 STI levers.

Thanks.
Is There A Shiftmate That Will Match Tiagra 4703 Sti Levers (10 Speed) With Mtb Chainset?
By

Subsequently to buying a frame I have discovered that it will not take a road chainset. Having bought Tiagra 4703 STI levers, F & R dérailleurs (and triple chainset) I would like to use what I can to build a touring bike. (My reason for 4703 STI levers was the "clean" cabling under the tape.
Hi,

As long as you fit a touring type chainset so the ratios are 26-36-48 or larger then you don't actually need a Shiftmate as your front derailleur will be able to cope with the range without any issues. We fit this sort of set up to our Thorn bikes all the time.

Thanks.
Shiftmate 8 Component Compatability

Hello,
I want to extend the gearing on my road bike using the Shiftmate 8 and a Shimano M8000 rear dérailleur. The bike has a 50/34 crankset and 11 speed Shimano ultegra STI shifters. Which M8000 RD should I use with an 11-42 cassette (medium cage gs or long cage sgs). Also, which Shimano 11 speed chain is recommended for this setup? What changes would you recommend for the dérailleur (gs vs sgs) or chain if a larger range cassette is used such as a Shimano 11-46 or SRAM 11-50? Can I expect shifting to be a lot rougher with these larger cassettes? Thanks for your advice.
Hi,

The SGS would be the recommended option as it will be able to take up all of the additional slack in the chain. Any Shimano 11spd chain should be suitable as the Ultegra and XT groupsets actually come with the same chain. We would not recommend using anything bigger than a 42t largest cog when using a 50/34t front chainset as it is unlikely the chain will be long enough and the derailleur may not be able to cope.

Thanks.

If I use the shifmate 8 can I use 11s shimano STI levers with a 11s XTR derailleur can I then put a Sram xg-1150 Cassette? I am using a 50/34 crankset at the front. Another question is if I do use this setup can I then go on the big ring at the front while being on the big cog at the back without snapping the rear derailleur, I know it’s not good for chain alignment but id rather not spend 100 euros on a derailleur and have it broken because of an accidental shift.
Thanks in advance.
Hi,

The Shiftmate 8 will indeed allow you to use 11spd Shimano STI levers with an 11spd XTR derailleur and a Sram XG-1150 cassette. We would not recommend using the big cog on the rear when in the outer chainring, the chain won't be long enough to cope with this so could end up damaging the rear derailleur.

Thanks.
Jtek Shiftmate 8 - Compatibility With Shimano St-Rs505?
By
05 Aug 2016
Dear Sirs,

I am interested in combining the Shimano ST-RS505 shifters with a Shimano MTB derailleur (11 speed). Is Jtek ShiftMate 8 compatible with these shifters and will it work correctly with an 11-speed derailleur like Shimano XT Shadow Plus RD-M8000?

Moreover, if these components are compatible, what is the biggest cassette that I can use given that I will use a compact 50-34 Shimano 105 crankset (e.g. FC-5800)?

Thank you very much in advance.

Best regards,
Spyros Zoupanos
Hi,

The Shiftmate 8 is the correct part to use those shifters with the XT M8000 rear derailleur. There is no limitation to the cassette size, you could fit either an 11-40T or an 11-42T cassette. You'll just need to be sensible with your gearing selection (so not crossing the chain too much).

Thanks.
