I have butterfly bars but it would be the same with straight bars. If I have the Rohloff shifter to the right of the brake, it doesn't leave much lever to get your fingers on. If I put it to the left, the reservoir of the hydraulic lever stops me getting a good grip of the shifter. I might try something similar, like on an extension bar.

If you are using standard Shimano MTB hydraulic levers, they typically have short lever blades designed for one finger braking. Shimano also make Trekking versions of the levers with longer blades designed for three finger braking. I *think* the calipers are cross-compatible between both Trekking and MTB brakes, but the Trekking version might not have the 'Servo Wave' function (which I suspect is not necessary with a longer lever anyway).

The MTBR thread below shows the Trekking levers used with SRAM Gripshift. Note that an additional wrinkle with hydraulic levers (unlike cable levers) is the reach adjust knob, which limits how close the lever can be moved towards the shifter, although it seems that the knob can be removed and might be replaceable with a set screw to increase clearance.

Availability of the Trekking components in the UK is poor, but some of the German retailers sell them, e.g.

I use the three finger T611 cable levers with mechanical disc brakes. The lever extends ~20mm beyond the plane of the end of the Rohloff shifter, and I find them easy to reach and operate.

On my Ogre I have the Deore M-6000 brakes, I can quite comfortably get two fingers on them, really that's all you need, one would be plenty!
I can do you a photo in the morning if you like.
On another bike I have a single Deore T-6000, though it isn't used with a Rohloff shifter. As Slowster points out is a longer lever version of the same brake, they are identical in all other regards.
There's also the cheaper range of Shimano brakes which are found on many E-bikes, mine included. They come in several versions, not all part of named groupsets, I think these are intended for hybrid or trekking bikes and have longer levers. I don't notice any difference between these and the Deore,
Have you used the brakes before? If not I'd suggest fitting them and the shifter in the normal way and seeing how it works out, you might find you don't need as much lever as you'd think.

I can use the levers as they are but I'll definitely think about the longer ones.

My Rohloff shifter and brake lever are arranged conventionally, ie they are both on the "thumb side" of my hand

However, I could "reverse" the brake lever, fitting it to the "little finger side" of my hand. Would that work for you?

I don't quite follow you, colin. Here's my setup just now. I can live with it.

On mine, I could put the brake lever next to the join between the transverse bit of bar and the forward extension, with the lever blade pointing forwards. The Rohloff shifter and the brake lever would then be either side of my hand. ...this works with a cable brake.

On yours, you could fit the Rohloff shifter at the very end of the bar, leave a gap for your handgrip, and then fit the brake lever with the lever blade pointing towards the Rohloff shifter. You would then have one control each side of your hand, but I don't know if the hydraulic lever would work "upside-down".

Or, you could leave the brake lever where it is, then have a handgrip, then fit the Rohloff shifter; but doing it this way the Rohloff gear numbers would be upside down, and you would be working it with the "wrong" side of your hand.

(My Rohloff gear numbers are side on, but I don't very often look at them anyway. When I fixed the shifter here

I couldn't see the index mark you read the gear number against, and I glued some stuff on that I could feel so that I knew when I was in gear 11 (direct drive)
But most of the time, who cares? Just enjoy the ride!
