Can I use this with an S7000-8 alfine hub?

By Andrew

08 Jul 2024

Does it make a difference that it displays 8 - 1 rather than 1-8?
i.e. Does is pull the same length of cable for each gear change?

SJS Customer Service:

Yes, this will work with both Nexus and Alfine 8 speed hubs, however due to the design of the IGH the shift action does work in the opposite to a normal trigger shifter. SK 08/07/24

What brake lever is it compatible with?

By JP

16 Apr 2023

Wondering what brake lever can be used with this shifter to save space on the bar.

SJS Customer Service:

Pretty much all flat bar brake levers will work with these shifters, you will need around 20-30mm of space for the lever clamp depending on the lever. SK 17/04/23

What is the clamp size?

Im trying to upgrade my sons bike from shimano revo grip shifter?

Does this facilitate 'standard' shifting pattern #2

By John

10 Jul 2020

Sorry about the question...Is a thumb press changing to an 'easier' gear and finger press to a harder one?

SJS Customer Service:

tumb is shifting up into easier gears, and finger pull into lower gears.

Does this facilitate 'standard' shifting pattern?

By John

10 Jul 2020

Just wondering if this changes gears in the same direction as a standard derailleur or is it reversed - Hoping its thumb press to advance the gearing and finger to gear down. I am planning to use on a Nexus 8

SJS Customer Service:

Yes, so thumb press to go up and finger pull to go down

Could this be used with a 7 speed biopace setup and match the gear spacings? Thanks.

By Martin

SJS Customer Service:

it would depend on the front mech, 7 and 8 speed spacing is as near as matters identical, you'd need a 7 or 8s MTN front mech such as Shimano Altus FD-M310 8 Speed Conventional Swing Front Derailleur - Multi 28.6/31.8/34.9mm (SJS Cycles part number : 37286) RT

Does it come with rubber boot

Would it fit onto a drop bar handle bar? looking to convert single speed to a hub gear

By Rob

04 Dec 2019

SJS Customer Service:

Hi there,

You should be able to fit this on the flat part of the bar if it has a 22mm diameter.

Thanks.

By Kim

SJS Customer Service:

Thanks
