12 speed with a 10/50 cassette?
 

I have always been happy with triples and 8 speed cassettes for derailleur touring bikes. But, I know some of you are always looking to buy the latest, ... ... so get ready to grab your credit cards.

With the price tag that system has it's a lot cheaper and also more sensible in every conceivable way to get a rohloff.

TinMSN, Here's a possible GI make-up using 35 mm tire and a 22-32-42 crankset.

your 1 st replacement cassette will need a Mortgage to afford. !

With one chainring, 10 to 50 gives you a 500 percent range with 12 gears.

And my Rohloff bike has a 526 percent range with only two additional gears, so they are pretty close.

The oil changes and very rarely needed rear sprockets on my Rohloff would be a bargain in comparison.

I suspect that the derailleur cage will not take up the slack with more than one chainring.

A triple provides plenty of range and close cog spacing. Modern mountain bike drivetrains are designed to avoid interference of the chain with very wide tires. Touring bikes don't have this issue.

My Bike Friday - Rohloff due to the small wheel could be Lower Geared , and by a double chainring the range extended considerably upward .

cool, 12 speed. Like with everything, with time, price, robustness and availability will get better.
As much as I am realistic about using X speeds for a given price/performance/robustness factor, more speeds equals closer cassettes for the same wide range that we need for touring, but its always nice to have closer shifts (for me anyway)

technology advances, its the way it goes.

I think that the 11Speed and 12Speed is a overkill for bike touring so say with 8Speed, 9Speed, and 10Speed for bike touring

Quite possible. Mainly I just wanted to show that with only one chain ring there is a situation where either the bottom maybe isn't low enough, or that top maybe isn't high enough using a common touring crank set option. Also to fit the chart I left out the 10T cog, which I wonder if there will be chain / chain stay interference on some bikes (?). Trimming for a head wind or a tail wind looks to take one front and two rear shifts for a close ratio.

I'll pass.

Well it's interesting as the 12, 14 16 18 21 24 28 32 is the same cogs as a 9 speed 11-32

If they come out with a 13 nobody is going to buy a 13. Have to skip it and go to 14. I always wondered if modern highrise bldg. have a 13.

If I had a bunch of money, I would put a Rohloff on my LHT but I've studied it some and think I would need DT to do that. Or maybe a Troll. Then I would need new wheels also; handmade (well, I guess that's all you can get anyway but the front gotta match the back). I always liked my belt drive Harley Davidson so I might as well get the hacksaw and go at it on my frame...don't know if that modification is being done (well) or what it would cost. I'm sure some would say go custom frame but I don't know enough about it to compare costs. I've looked at the cyclemonkey website but I don't get too much from it.

After you buy the hub, I see much additional outlay of $$$ for cables, misc. stuff and especially shifters depending upon your bike and bars. What about running those cables...I could see problems with that.

If I had a crystal ball I would say that things like Rohloff are the future of bicycles along with belt drive. I won't bet money on it but all those Harley riders said the exact same thing about belt vs. chain drive way back when.

Is it compatable with a double or triple or just a single crankset?

I would guess this stuff is for the fat tire bicycles exclusively, 148 rear hub if I remember correctly. Sounds like if you wanted it for touring means custom frame.
I've heard that internal gear hubs are less efficient than derailleurs. ?? But there are a lot of pluses for internal gear belt drive. I'm not gonna be the one to tell Co-motion and such that they are doing something wrong.

Price wise this set up is within the price of the top end road groupos.

A rohloff hub is nearly as efficient as derailleur systems. Sometimes even more efficient due to the extreme chainlines today's derailleur systems see.
