will this fit on a 25.4mm diameter handlebar?
14 May 2020
the ring seems adjustable but is there a range?
Hi, no, the bracket is not flexible enough to open out to 25.4. Thanks
Will this fit the Alfine SG-S7001 8 speed IGH?
13 Jan 2020
and what are the main different between this and the more costly Jtek 8 speed shifter to 99,99GBP?
Yes these work nicely with the S7001-8.

The Mk1 Jtek shifter is a slightly larger, but much more adjustable unit. The lever is a nice length so shifting is slighter, but this is a smaller shifter!

For which Alfine hubs will this shifter be "push away from you for an easier gear"?
14 Oct 2019
I understand that different generations of Alfine / Nexus 8-speed hubs have the shifting cable operation reversed. I am thinking of using this shifter in a new set-up, but would like it to shift like my old derailleur gears, i.e. push away from me to get to an easier gear.

Which hubs would give this action with this shifter?
For all Nexus and Alfine 8-speed hubs except the S7000 series Alfine hubs, the cable is loosest in the lowest gear. Therefore, all shifters will be push away and get harder as they pull more cable.
