My first reaction was to say how much I hate your shifter solution but after considering the tall stem, the brake levers pointing up at a 45-degree angle and the drops pointing at the ground, I realized that your riding position is much more upright than mine.  Maybe that's why mounting the shifter high and inside doesn't work for me - it forces me to sit up a little in order to get my hand at the right angle to shift.  Someone riding in an upright position would prefer it mounted up high and would not like it on the bar end where they would have to reach down and out to shift.  Even though you can easily reach it, the photos of your hand on the shifter indicate that the position of the shifter requires an awkward wrist action to rotate - you really can't shift with your fingertips.  (In other words: I still hate it, but then it's not my bike.)

Hi All
This is the best I find with Drop Bar's!
After trying lot's of mounting's and trying to make a new shifter etc, I made a mounting to mount on the side of my stem!
(I am now running Jeff Jones Loop H-Bar's)

And very well, I might add!  A stunning job of placement and execution, Pete. I can't see for sure with the shifter mounted, but it appears you might have used sheet-metal bent 90° and the perhaps brazed or TiG'd a 22.2mm stub onto that?

I'd love to hear all the details, as well as some more about your stem-cap. Was it designed to hold your GPS?

Very nice.

All the best,

Dan.

This is precisely how my tandem was originally set up:  http://www.thorncycles.co.uk/forums/index.php?topic=4049.msg20378#msg20378

Thought I would share a couple of different takes on the drop bar conundrum I have been toying with.

Stub tube mounted to bars.

Think the Gilles Berthoud is the way to go if money no object.

Interesting mount - Not seen this before, thanks for posting. Nice neat finish there.

Hi Chris, and welcome to the Forum!

Steve is absolutely right -- that's some stunning metal work, and it just looks fantastic as does the whole bike; you can really be proud of what you've done. I'm so impressed with the nice, clean job you did on the cable routing,too. It looks "factory original". That RST and the Romahome Demountable are artworks as well. Wish you were my neighbor IRL.

Is there a chance we might see a photo of you reaching to shift the Rohloff? I'm mightily intrigued by how it works in practice, and give you full marks for one of the more innovative approaches. Thanks for sharing!

All the best,

Dan.

Hi All!

Just to show the variations are many, here's another version of the Rohloff-as-bar-end-shifter.

The interesting twist is it is "backwards", with the shifter forward of the cables. It meets the owner's needs and allows actuation with the smaller fingers on his right hand, and uses the older triangular Rohloff grip. Original photo link here:

Closely cropped version of the photo attached below.

Best,

Dan.

We have a setup on our Hase Pino tandem were the Rohloff grip is operated by the palm+small finger of the hand.  It works but becomes difficult to use in hot conditions when the hand is wet due to sweating. 


(this picture isn't from our Pino, but ours is similar).

Also the cables at the end of the drop bar aren't nice at all.

Blimey. I'm astonished by how wrong that looks. I'm thinking of a hubbub adaptor for a drop bar experiment on my bike. I now know which way round it has to go.

On my testbed bike (sorting out handlebar and shifter options before I buy a Thorn/Rohloff) I now have a Shimano twistgrip for my Nexus 8 premium hub on a cheap imitation of the Hubbub - a piece of small diameter aluminium tubing salvaged from an old camping chair, one end glued inside the end of the drop bars with Araldite and with a short section of MTB handlebar glued over the other end. I reckon a piece of wood dowel might also do the trick.

So far, I quite like the shifting action, but haven't yet had the time to do any longish rides with the setup.

Retroshift makes brakes for drop bars that mount a lever shifter just in front of the brake lever.  You can't shift from the drops, but they do have other advantages.  It should not be too hard to mount a standard Rohloff shifter in place of the lever shift.

I don't think you could shift without moving your hand, but this seems like the minimum movement possible.

http://retroshift.com/store/products/cx1/cx1-green-plus/

The ultimate for minimum maintenance should be a Rohloff hub and a belt drive.  We ride a Santana tandem, but the ultimate tandem solution should be similar to the single solution, but with two belts.

If it did fit, it might come to hand quite nicely. It might look a bit crazy sticking out the front like that... The shifter (especially the old one) is a chunky piece of kit.

I've just had my first experience of using the hubbub adaptor on drop bars. It works well, but it's going to take a bit of getting used to. I hadn't fully appreciated the convenience of the shifter right where you want it to be. I'm also having to think about which way to turn the thing, but I'm sure I'll get over that hurdle fairly quickly.

Well, this Forum is a good read -- style, substance, courtesy, practical suggestions, what more could a first-time reader ask for?  The early reference to Alex' excellent tour of the horizon was really helpful, and the extended discussion has only added to that.  So, thanks, guys.

I logged onto the Thorn Forum because I'm seriously considering buying a Rohloff-equipped touring bike in the next 12 months or so, most probably from SJS.  This is because I'm fed up with the fiddly-verging-on-seriously-irritating (thankfully, not catastrophic) derailleur problems I've encountered on some longish rides, one from Ottawa to Halifax, another from Amsterdam to Vienna this past Sept/Oct.  I'm an admirer of German engineering--one of my two-wheelers is a mid-80's BMW airhead--and fortunately, I can manage the price of the Rohloff.  My general approach to these questions has been, "Buy quality or repent at leisure." 

BUT, until now my reservation about the Rohloff has been the issue of mating the Rohloff shifter to drop bars.  I've finally found very comfortable bars for my touring bike -- a set of Velo Orange Grand Cru randonneur bars--and have been wrestling with the problem of using them with a Rohloff shifter.  The folks at my local shop suggested Alex' preferred option in his review -- the 55 mm Thorn accessory bar.  Then, I learn that Co-Motion offers a shifter mounted to the bars themselves, ā la GB.  Happy coincidence!--I expect to be in Oregon this July so will visit them for a discussion: all else equal, will it fit with the mounts for my Arkel handlebar bag?

So, at the very least there seem to be several routes through the thicket.  Will post my experience in sorting all this through in the next year-plus.

Thanks for your help.
