I recommend this product
Cons£££, esp. as thumbies
ProsBetter than any click-shift system x1000
Been using these with Paul adaptors as thumbies for 10yr , many many thousands of Km. No problem, indexing perfect, reliable, tough, convenient.
Great bonus with Paul thumbies is they can easily be removed from bars for packing bike on planes / busses - vulnerable shifter tucked out of harms way.
Work OK. Some service issues.

Fairly easy install but supplied cable outers and inners may be too short. Cable stops didn't fit one bike. Work OK. Grey caps fall off or wear through and no spares. Awkward to lube but seize up if not.
Questions & Answers (15)
Hi, when on indexed mode, are these compatible with shimano road or MTB rear derailleurs?
06 Jul 2022
I’m wondering what RD’s I can use this with. Alivio and Deore ok? (Both 9spd) and would be running 1x
As they are 9 speed they will work with 9 speed MTB and ROAD since they use the same cablepull.

Could this shifter be used for Brompton 2/3 speed
12 Jun 2022
We have not tested this so we cannot confrim.

Can these be used as replacement downtube shifters on 9 speed Shimano bike
13 Mar 2022
Thank you for your enquiry, yes they will be fine

Can I use this in friction mode with any 10 speed road or MTB RD?
08 Jan 2021
Yes you can, but only in friction mode.

Thanks! 08.01.21
Can you get replacement grey caps?
13 Jul 2020
One of mine fell off recently which is a bit of a bummer - would be great if it was possible to get a replacement cap. Any chance?
No replacement part is available- i would recommend using grip tape, Sugru or silicone heat shrink as a fix.
Indexing problems
11 Nov 2019

Having recently bought a pair of these, I've found that, since removing and then refitting them (I had to replace the brake levers), the indexing on the right shifter no longer works, but it does in friction mode. Can you help?

We can only advise taking the shifter to a local bike shop to refit. We could not really offer much help without seeing them in person. Sorry!

Compatibility with Shimano SLX M670 10 speed rear derailleur and triple chainset
15 Jun 2019
Hi, will this work with a 10 speed MTB (Shimano SLX M670 long cage) rear derailleur in either friction or indexed (preferable) mode? Also, will the front shifter work with a triple chainset? Thank you.

yes, this will work with a triple chainset and may work with 10spd although we have never tried this so wouldn't be able to say for certain.

Can I buy the fixing kit parts?
27 Apr 2019
does anyone know the part number for the clear looking outer cable(that sits under the bar tape)
HI, are you looking for our part 20270 ? Thanks 29/04/2019
Can this work with 10 speed campy?
29 Nov 2018
1. What is total cable pull (one end of travel all tne way to other end?
2. Will this length of travel be sufficient for the 9 speed shifter to work in friction mode with campag comp triple rd and 10 speed centaur cassette 13-29?
3. If not which model of friction shifter will work with thiis comnination
We do not have these shifters set up to measure the cable pull I am afraid, we would expect the shifters may work with the 10 speed stuff, but again, we have not tested this.

Are there spares available for these. I have an older pair of these, that are missing the plastic ring that's held by the screw on the RH shifter.

Can I use these (in friction) with SRAM X.9 9 speed rear mech
12 Apr 2018
Hi there,

Friction shifters will work with anything as there is no indexing!

Do the frame stoppers include barrel adjusters?
25 Mar 2018
The down tube cable stops do have built in barrel adjusters yes.

Would These Work For 8 Speed Cassette To? Thanks
26 Oct 2016

Although the shifter is indexed for 9spd it can be used with an 8spd derailleur as well.

Friction Setting As Well?
25 Oct 2015
These have been known for a long time to include a friciton setting as well. Does this model have this, too?

The left hand shifter is permanently friction and the right hand can be switched between 9spd indexed or friction shifting.

Are The Covers For These Shifters Available As Spares ?
17 Dec 2013
Plastic (Rubber?)cover/sleeves on the bar end shifters stolen while my cycle was parked unattended.
Now not quite so cumfortable to use. Can you help please?

I'm afraid that the covers you are after were never made available as spares.
