Hi All!

Co-Motion have updated their Rohloff shifter for drop handlebars. See:
http://www.co-motion.com/index.php/product/rohloff-shifter

Their newsletter says...
Quote
We have had some great feedback this year since we released the Co-Motion drop-bar Rohloff shifter, all very constructive. We listened and and have made our new Rohloff shifter more user friendly. For those with smaller hands, we have been able to decrease the overall diameter. To improve grip in wet and cold weather or for gloved hands, we've added machined cross-hatch knurling.
It also has laser-etched numbers for greater visibility.

Earlier discussion of my firsthand view of the introductory model here, with photos:

Best,

Dan.

The previous version was beautiful with its smooth black anodized surface but very slippery even dry.

This new surface will surely provide much more grip but I am afraid that it won't be comfortable, especially after hours of ride with many shifting.

What is so hard about putting a rubber grip on the rotating bezel ??

Also, does this new model seal off the cables from the elements? A big flaw with the first version.

Hi Pete! The Co-Motion shifter has always had o-ring seals, but the Berthoud model has used open cable runs.

Best,

Dan.

Has anybody here tried the Origin8 Pro-pulsion Road Ends as a way of getting a drop bar whilst using the Rohloff twist shifter.

Hi Mac'!

I haven't, but I do recall seeing just this setup in either the SJSC blog at one time or pictured in an earlier catalog

A photo of the setup appears (tiny) on the ad copy for the Origin8s on the SJSC page:


I sometimes like to ride on that upper curve of my drops, and would find the clamp there to be uncomfortable. All other positions would be usable, though.

Best,

Dan.

Re: Drop 'bars & Rohloff: new approach with EX box replacement "Rohbox"
« Reply #171 on: August 08, 2015, 03:21:38 PM »
Have a look at www.rohbox.de and/or https://www.youtube.com/watch?v=HbXtgQQTbvs. Instead of inventing yet another compatible shifter or drop bar Georg Blaschke proposes a ratcheted EX box replacement that is compatible with every shifter that can repeatedly pull a length of cable.

regards,
Ludwig (not in any way connected to Blaschke bikes)

Nice one, Ludwig, and welcome to the Thorn Cycling Forum!

I looked at this while the Forum was down, and am impressed by its simplicity and direct design. I'm not sure how long the springs would last, but even if they eventually failed, they would be easy to replace. Surely nice to see a solution that cuts cleanly and clearly to its goal with utter simplicity as a virtue.

Looking forward to some long-term reports from users.

Best,

Dan.
