Works Really Well

ProsSimple,works well
Using on Salsa Cowbell bars with an Alfine 8. Since getting the cable properly adjusted (not a trivial task) it's been working really well. Love the ability to swipe through the gears. For info, I've routed the cable fully around the bars under the bar tape and it's been working well (and looks nice and tidy too).

ConsSeems expensive BUT great quality product!
ProsFaultless reliable shifting and indexing!
Wow! Love this!

I'm using a base bar/bull horn bars on my single speed and I wanted to make it into my winter bike! Going out with a group on a single speed is exhausting so I plumped for an alfine 8 hub but wanted to keep the bull horns! Not only is the jtek aesthetically pleasing but it is a sturdy alu machined unit, even the lever. The indexing is really good consistent, light and responsive but stiff enough not to change by accident. I have done a number of rides with it mainly in raining and wet/dark conditions. Hill reps, fast group riding and chilled longer rides...and it has performance faultlessly!

I think any issues others have had cant be put down to the Jtek it is after all a pivoted lever just pulling a cable. These are issues with the hub itself. Highly recommend!

ConsNot, working,after,one,month,all,weather,use
ProsLight, attractive
After fitting it on the Shimano 8 speed after about 4 weeks the lever started getting stiffer until I could hardly change the gear. I thought it may be grit/mud/dirt in the ALFINE hub. Cleaned and reg

Compatible With Aerobrake?
By
24 Oct 2015
Hi,

I really wonder if the shifter is compatible with Jtek Aerobrake system (integrated one)? If so which of them (Shimano/Campa)? Does the shifter work with newer shimano hubs like nexus 6010?

Thank you.
SJS Customer Service:
Hi,

I'm afraid the construction of the Jtek bar end shifters is much different to that of Shimano or Campagnolo so the Jtek aero brake levers can not be used with them. This shifter should be compatible with all 8spd Shimano hub gears.

Thanks.
Does The Jtek Work With A Sturmey Archer X Rk8 (W) Hub
By
29 Mar 2015
SJS Customer Service:
Hi,

This Jtek shifter will not work with Sturmey Archer 8spd hubs as they use a different cable pull to Shimano hubs. Jtek do actually produce one specifically for Sturmey 8spd hubs which is SJSC part number 19964.

Thanks.
Compatibility With Alfine Sg7000 Hub
By
25 Mar 2015
Any idea if this shifter works with the new SG7000 Alfine hub? I asked JTEK themselves and they said they didn't know. Has anyone tried it yet?
Thanks!
SJS Customer Service:
Hi,

We haven't tried it yet, but as far as we're aware the cable pull is still the same for the SG-7000 as it is for the other Shimano 8spd hubs so it should work fine.

Thanks.
Bowden Cable
By

Hi there, does the shifter include a bowden cable? If not, does it require a specific one or do i just use my standard Alfine?

Regards,
Denis
SJS Customer Service:
Hi,

This shifter does not come with a gear cable but you can use any Shimano type gear cable including your previous one from your Alfine shifter.

Thanks.
