best internal shifting hub?
 
What is the best internal shifting hub on these important points:
- reasonably lightweight compared to a road group
- reliable operation
- parts are available from the usual channels, not some guy working
out of his garage.
- has more than 3 speeds.

The 14-speed Rohloff Speedhub should satisfy all these requirements (and
many more), especially as you didn't specify any price limitations. See:

http://www.rohloff.de/?p=PRODUKTE/SPEEDHUB

It's about $800, available for example from Harris Cyclery.

Depending on one's definition of "reasonably lightweight", there may not be much
left.

Rohloff adds about two pounds to the bike, is less efficient, makes considerable
noise, and costs an arm and a leg.


I just bought a second one for my hardtail.

How about for drop bars as well?

I never thought I'd see the return of stem shifters!

That Surly with 2 sets of bars is awesome.

A German company (Norwid) makes a separable road
handlebar suitable for mounting the Rohloff twist grip.
Last I heard, these bars were available through Rohloff's
US office (contact info at www.rohloffusa.com).

Or you can make your own twist grip:

It seems like all gearhubs from 4 to 14 speeds weigh about the same
1.7 kg, give or take. With some you get a brake, making those
effectively a little lighter.

Only the Rohloff Speedhub gives step sizes between gears that compare
to a road group. However, Sachs's and Shimano's 7 speed hubs give
overall ranges similar to that of a road bike. (Road bike with 53/39
crank and 12-23 block: 260% Sachs/SRAM 7 speed: 303% Shimano Nexus
7-speed: 244%)

If you need lots of gearing range and you can afford the Rohloff, then
that's the one for you. I have had two, and I don't think anyone
would find reason to switch back once accustomed to the Rohloff.

If the price of the Rohloff is too much committment and/or you would
like a drum brake, I recommend the Sachs/SRAM Spectro 7 speed. It is
the most free-running gearhub (with more than 3 speeds) I have used,
it seems quite durable, and the brake works consistently with minimal
fade.

I am interested in hearing a little more from Chalo on the Rohloff, and
his reasons for buying them. (Chalo, aka Bluto is knowledgeable about
machining, materials and manufacturing, and is a super-size kind of
fellow.)

Chalo, have you ever taken one apart, either out of curiosity or
necessity? If so, did inspecting the innards lower or raise your
initial evaluation?

What about the durability of the Rohloff hub? I always heard about how
great Phil Wood hubs are. I was very disappointed with them and
repeatedly trashed the insides (esp. where the pawls bite into). You
would think with all the gears inside the Rohloff that something is
likely to go in a relatively short period of time. I weigh over 200
pounds too. You can imagine that I'm seeing myself spend $800 and then
thrash the gears and its junk on the side of the road. Then I'm
opening the hub up trying to figure out where 100 gears fit in there.

So you're saying that there is more friction? Is that when coasting?
only when applying force to the cog?

I think the shifter on drop bars is not ready for prime time. If only
someone could come up with a decent shifter for drop bars. I like the
concept though. If these kinds of hubs are very reliable, then they
sound great.

Are we saying that if we take a road bike with say Ultegra trip and
STI and switch to Rohloff and no derailleurs that its going to be
roughly 2 pounds heavier? I'm just trying to get a ballpark figure.

I wish Shimano was more flexible with the road group components. As it
is STI is not cyclocross friendly in terms of brakes.
