Rohloff 14s & tandems:

Yes. We have a tandem using one but haven't put much distance on it yet. No problems so far. I also
know a tandemist down in Melbourne who has been using one on a tandem for a couple of years with no
problems that I am aware of.

Chris Timm has a web page about his Robloff tandem at
tandem-fahren.deTandemTechnology.htmlOpen ↗. According to the page, he
rode it in the TransAlp MTB stage race, which would have been a pretty severe test of equipment, and
had no problems at all with the hub.

I use a Rohloff hub without problems and I weigh over 360 lbs. The only symptom I notice that may be
due to unusual drivetrain torque is a hesitance to shift into some gears unless I attenuate my
pedaling force.

I use a 44-16 primary drive ratio to keep maximum torque down somewhat compared to the lowest
permissible gearing specified by Rohloff.

I am told that the tandem version of the Rohloff Speedhub is identical to the normal version in
every detail except spoke hole diameter, the tandem hub being drilled for 13ga. (2.3mm) spokes.

Yes, we have one on a tandem, haven't used it much but it seems good so far. We had one slightly
worrying moment last time out when it _appeared_ to be slipping while we were pedalling hard in a
low gear, but since many heavier teams than us have used them for some time I'll put that down to
some other unknown cause unless it recurs. Even though the shifting is improving with practice and
wear-in, I can't ever see it being quite as good as a derailleur while riding along, but shifting
while stationary is a whole lot better, as is cleaning the bike (MTB) after use!

I had an occasional slip (on a single, not a tandem), but I found that they only occurred when I had
my hand on the twist grip. It's easy to apply a little torque to the grip without even realizing
you're doing so, which can pull the hub a little bit out of gear. Since I stopped doing that, it
hasn't slipped again.

Oh good, I was hoping someone would say something like that! Since my natural hand position is on
the shifter, and we were honking up a steep bit at that time, it's a fair cop.

Not using one on a tandem, but I've got a couple of the hubs on other bikes.

Only recurrant problem I've found is oil leaking. Still haven't gotten to the bottom of it, but I
think the end is near with the installation of a couple of gaskets that Rohloff USA sent me.

I don't understand that comment. I have two Speedhubs, and I say, only partly tongue-in-cheek, that
I would give up bicycling if I had to go back to derailleurs. The short shifting interval, 1/100 sec
vs 1/10 sec, and the ability to shift under load, not to mention the even stepped shifting, make it
ideal in my opinion. Under heavy load, i.e. uphill, I have to ease up a bit to shift, but I can
shift going uphill without loosing momentum. This can be very helpful on long climbs as the grade
changes, and when climbing after a downhill, it permits be to step down on the gearing as I move
into the uphill phase. Also, I don't have any derailleur misalignment problems.

I had some leaking problems initially, but Rohloff replaced the seals and that seems to have solved
the problem. I recently flew to Spokane and back, and to Spain and back, and there was no oil in the
case (my back has S and S torque couplings as well).

Well, I find I have to ease up more with the Rohloff than with a derailleur (which is slightly more
awkward on a tandem than it would be on a single). I also find the shift between 6 and 7 is a bit
unreliable (it can jump into 12 if I try doing everything too fast). I'm not denying it has many
other advantages, and I don't regret getting one.

I've replaced the big seal twice already - but Rohloff never told me about the little one. About the
third time around, I got an envelope with the little one in it too and called to find out what it
was..... I'm *pretty* sure I'm putting them in the right places now - but a Rohloff's inclusion of a
drawing would have helped a lot...

The shop that built my bike, sent the wheels back to Rohloff USA, and they put in the new seals.

Yup.

Several tandems with Rohloff Speedhub on the german speaking tandem list, no problems.

This unwanted shifting is why I dislike twist grips in general. Last weekend we tried out a
Rohloff-equipped tandem on an off-road tour. If ever I'd choose a Rohloff, I'd place the shifter
quite far inward so you don't have to rest your hand on it. Otherwise it's nice to be able to shift
on one side only. We dislike the noises in gears 1-7 and on several occasions had it shift into 14
when we wanted to go from 7 to 8. This is not uncommon.

Still, it's an impressive piece of kit!
