I'am going to buy a Rohloff hub but before buying a specific frame i would like to use my Rigormootis as a testcase , is it ok to use the Speedbone on the disctabs of a Moots frame and does anyone tried this already?
Thanks
Stef

I have never seen a failure from the Speedbone connection to the disc tab. That being said, I almost always use the OEM1 axle plate that fits into the extended Rohloff dropout. If you run Paragon sliders, they sell the Rohloff extended version. Also, some frame makers incorporate this design into their non-sliding L dropout.

Solo,
You can use the Speedbone on the Moots disc tab.
Thanks,

Check out the Monkey bone from Cycle Monkey.....
How much extra weight does a Rohloff system add to the bike compared to a conventional system of similar gearing (assuming XT)?
I went to weightweenies.com for the numbers.
I compared hub, cassette, front/rear mech, shifter/brake levers and cranks
1. First example is shimano XT/ultegra with a rear disk option,
2581 grms or 5.69lbs
2. All dura ace, hugi hub, non disk
2243grm or 4.94 lbs
3. Rohloff disk version, lightweight double crank, and cane creek brake levers, includes shifter
2681 grm or 5.91lbs
So just about the same at as a mid level/standard gear setup. A pound heavier than a very light setup without a disk.
Thanks for the info !
Extra weight is something between 400 and 800 gr depending on the components you used before, Rohloff specfic frames are heavier too.

Subjective question...
How does the Rohloff compare to a conventional derailleur system in a practical sense (shift quality, everyday usability, durability)?
An do they stay in adjustment or are they prone to be finicky and require constant maintenance/adjusting?
In short BULLETPROOF. Stays in alignment fine. Better I think than derailleur systems. Many less components and it lasts for 10's of thousands of miles as opposed to 5K or so with standard systems. Shifting is great but different. It uses a twist knob versus levers. Adjusting to a handlebar emd shift takes a bit of time. On the very good side you can shift into any gear at any time. No need to be moving.
BTW remember that even though the weight is at the center of the wheel it is still rotational weight. You can definitely feel the difference there.
What's the difference between Paragons slider mount that Jah posted a pic of and the 'Monkey Bone' that laeljon mentions, is it just a different brake mount setup?
Solo, sorry for basically hi-jacking your thread, I find the idea of running a Rohloff quite intriguing, thanks for bringing up the topic.

Any frame with non Rohloff specific design dropouts requires either the long torque arm arrangement or use of a Rohloff speedbone / monkey bone for hub anti rotation against torque forces. All well covered in the Rohloff hub manual. Standard vertical dropouts also require a chain tensioner
@Domestique
You can find all the info you'll need on the Rohloff site http://www.rohloff.de/en/company/index.html
On MTBR there are many topics about the hub.
After some tests i'am convinced this is what I need but i'll wait for 1 season to buy a Rohloff specific frame ( the truth : i want a Rigor wit EBB and Rohloff dropouts but cannot find one ;-( ), for this year i'am using the hub in a Rigormootis with discs and vertical dropouts but without a chain tensioner . Instead i use an eccentric BB from Trickstuff ( Germany), there is also one from Forward Components ( Canada) http://www.forwardcycle.com/
I don't think U need a chain tensioner with a hardtail....I have a Zirkel with Rohloff, White Industries ENO single chainring, Stans ZTR Arch, Gearx 2.2 with goop. 28lbs and absolutely love it and will never go back to conventional gearing. Check out the article at Spoke Wrench on the Moots Cinco they built with Rolhoff. They have been riding the Cinco for over two years....The Monkey bone is cleaner, less weight, and makes it easier to remove the wheel. I had the Mothership build the frame with cable routeing for the Rolhoff. I believe the added weight on the rear wheel actually helps in loose rocky steep climbs. I would post photos but don't have outlook express....just can't find out how to post.
The Zirkel sounds awesome.
How is the 'monkey bone' setup better than the slider setup Jah shows in his pic (or a 'speedbone' for that matter)?
Looks like they accomplish the same thing equally well.
Sorry...Trying to upload Photos....didn't work.
