Scott AT-3 bar & Rohloff shifter?

Hi all,

What are the chances I could mount a Rohloff 14-speed shifter grip on a
Scott AT-3 (bull horn type) or AT-4 (connected bull horn) handlebar?

I'm thinking of having my LBS build up a commuter/light-duty trail riding
bike with a Rohloff 14-speed hub, and I'm exploring the handlebar/shifter
mounting possibilities. I have trouble with hand numbness on flat bars, and
I thought one of those Scott bars (assuming they keep showing up on Ebay
for sale) might offer more hand positions, without going all the way to
drop bars and all the complications with mixing road and MTB components,
brake levers, etc.

However, it looks like the Rohloff shifter might not fit around those
curves on the AT-3 and AT-4. There isn't any way to split that shifter in
half for mounting, right?

After doing some Googling on this ng, I've seen the web pages with creative
solutions to mounting the Rohloff shifter... like the stem mounting shown
on Sheldon's site...

....or drop bars cut in half and mounted on a wide stem clamp, so the
Rohloff shifter can be slid over the cut end. I'm not sure that cutting the
bar would work with the AT-3 though. How would you fit the shifter over
that wider center section? Also the idea of cutting the bar makes me
nervous. I weigh 250 lbs. and can put a lot of force on a handlebar. Should
I just try to get a stem with enough length to use the stem-side mount
shown on Sheldon's site? Or do that with a stem extender?

I suppose one last possibility is that I could mount the Rohloff out on the
end of the AT-3 horn, but that would look weird, and probably isn't a great
location for shifting. Any other wild ideas?

Have you considered trying trekking style bars such as the ones Nashbar
sells

I once saw a Rohloff shifter mounted on a Koga-Miyata bike using these style
bars.

Nice! I didn't know about these bars. If the Rohloff shifter was mounted on
the outboard end, it looks like it wouldn't be as far away as it would be
on the Scott AT-3 bars. Is that where they put the shifter on the Koga-
Miyata you saw?

Not so good IMO. The Rohloff shifter is a substantial thing made
mostly of metal, and won't negotiate any bend as far as I can tell.

Consider using a different bar. Since flat bars give you trouble, I
should think that you'd want to avoid the Scott bars, since their
primary hand position is the same as any flat bar. There are plenty
of non-straight bars that, unlike drop bars, use normal diameter
tubing and have a straight section at the grip end. I use a Nitto
"All Rounder" on one of my bikes and I'm quite happy with it. "North
Road", "Priest", and Rivendell-specific "Albatross", "Dove", and
"Falcon" are all names used to refer to the same basic type of bar:

Any bar of this sort will accomodate the Rohloff shifter and real
no-nonsense brake levers. They can be mounted so that the grip
sections rise or drop from the stem, depending on the application.

The Rohloff shifter could probably be mounted on a Minoura "Space Grip".

Yes, they were located on the section of the bar close to you. The shifters
would really just have to slip on the straight section on open end of the
bar.

I put a set of these style bars (not the nashbar ones, but similar) on my
tourer this year. So far I'm pretty pleased although finding a long enough
stem can be a challenge. I sometimes use this bike with a trailer-cycle
attached and find these handlebars offer a number of hand positions, and
when you place your hands on the widest part of the handlebar it offers good
control in taming the wiggley 6 year old rider behind me.

Aha... for some reason I was thinking those bars mounted with the separated
ends outboard. Now I get it.

I just ordered one of these to try out. And thanks to everyone else for the
suggestions. I might try the All-Rounder/North Road type bar if this
doesn't work out, and that Minoura Space Grip accessory T-bar looks like a
good solution if all else fails.
