Any new internal gear hubs on the horizon?

I've heard of the 14 speed Kindernay out of Norway which is expected give the venerable Rolohoff a run for the money. They were supposed to have started sales by now but are delayed.

Aside from that, the only other mid to high end IGH's I'm aware of are NuVinci and Alfine. Possibly the 8 speed offerings from Shimano and Sturmey Archer.

They all have problems - good but expensive, acceptable price but poor efficiency, not that great of gear range (less than 300%, I'd say more than about 350% is good enough).

Are there any existing gems I've missed? Apart from the Kindernay, are there any other upcoming ones that look promising?

News you may have missed: the Shimano Alfine 11-speed IGH has a gear range of 406%.

Efneo out of PL , has just released the 3 speed internally geared single chainring crankset, a 28t with 2 overdrive gears

equivalent of adding a 40 & a 50t chainring, with out the chain coming off the 28t...
it turns faster than the crankarm, to achieve the 2 higher gears..

Merry Sales Imports, So SF Cal, has secured the US distribution. to their dealer account holders .. SRP about $500..

rollagain, I'm aware of the Alfine 11. It's among the ones I referred to as "acceptable price but poor efficiency". It has great efficiency in low gear range but awful at the high gears. Have look at:

https://etrike.wordpress.com/2015/09...nd-derailleur/

fietsbob, that one is essentially a triple chaining - just sealed. The gear ratios are too far apart to be useful as a standalone 3 speed.

Thanks, both.

I'm looking for an upcoming IGH (which I may not have heard of but fellow forum members may be aware of) with about 8+ gear or 350%+ range.

That's nice write when you get one and make your own revue...


most people write here from work during the day..



I will say it wont come from Sram,

They are closing the IGH division, they got by taking over Sachs of Germany, then shipping their production tooling to Taipei.

Ah the Thru Axle crowd will be served.. will it be cheaper? of course not, Norway is an expensive place..

Like Rohloff, initially was , they are targeting the Highest End of the MTB market and looks like all parts will be proprietary..

Interesting that the hub mechanism is separate from the wheel. I am not sure that it's a real advantage though.

Was kind of funny to read that their first mounting frames (whatever they call it) would be 28-hole only. I thought all the touring folks were into high spoke count. Did I miss something?

I know this doesn't help, but for me, it's Sturmey AW, and live with the limited gear range. I haven't been able to really persuade myself that the hubs with more gears are really worth the cost and complexity.

That's what I mean by good but expensive. Something with bit less range, and less expensive, but as good efficiency e.g. ~ 90 to 95% throughout its range (compared to 97% for single drive/derailleur) is what I'm looking for.

No such animal now or in the near future?

I dont work in a bike manufacturing company, on design, I doubt anyone hanging out here does .

for future casting, Fly to the next Taipei bike industry Trade show.. there is where the majority of the Biz is ..




You guys go OCD on IGH efficiency, why? data on Rohloff graphs out with peaks and valleys ,,,

want only 5% loss?, go single speed with a clean well oiled chain..

So no upcoming IGH's on the horizon?

No possibility of me going to Taiwan in the foreseeable future, let alone during the bike show period.

I wouldn't call it OCD. Why? Because efficiency matters. I can feel the difference between 80, 85 and 90% between 1 IGH and another. Everyone knows the pros and cons of IGH vs derailleurs vs single. I must have IGH.

True, even the gold standard Rolhoff graphline isn't flat. But notice it's the most steady among the lot. It's as steady as IGHs go at the present.

NB: The first of 3 graphs in that webpage of efficiency measurements can be ignored. The writer claimed that he improved the test to account to obtain steady averages. Therefore only 2nd and 3rd graphs should are valid.

this is just not an industry insiders forum, it's riders wrenches, and shoppers ..

look at some of the crowd funding sites to see who wants your money to develop their idea to the marketplace..

I resonate with this somewhat. I have had essentially bullet-proof performance from a couple of Shimano Nexus 8 hubs, with regular maintenance. I've been very happy with the Alfine 11 on my current commuter bike too, with regular maintenance. I've enjoyed having the extra gears on hilly rides.
The Alfine just needs an oil change, which is a snap to perform; the Nexuses have to be at least partly dismantled.

But I think I could easily get by with fewer gears, at least for commuting in Chicago. To this day I regret that I did not hang on to a Sturmey-Archer 3-speed hub that was on my "English Racer"... a Royce Union that my parents gave me when I was 13. I converted it to a 5-speed because... derailleurs. Sad!

why do you have to have IGH? if efficiency is so important, why not do the most efficient and go derailler?

I think people in the forum generally know the pros and cons of IGH vs der. I just want an IGH that comes as close to der efficiency as possible without spending a fortune on the Rolhoff. Don't need 500+ range of the Rol. OTOH, der usually only go up to 300% (single chainring).

I want an IGH in the ~350 to 425ish range which is higher than der but less than Rol, better efficiency than Alfine which is less than Rol which in turn is just a tad less than der, at much lower cost than Rol.

No such animal exists today, it would seem. Shame though. It would be a great market gap to fill.

take an igh & fit a lo-profile cassette to it while incorporating the rear-derp then a triple front crank set.

Truly an E-hybrid drivetrain system... E=expediency. Advantageousness for someone willing to travel a different business path with cycling.

Is that difference in efficiency something that can be felt? Or only measured if you have access to a power meter?
