Schlumpf 2014

Does anyone know what changes, if any, are being made to the next batch of schlumpf hubs.

shorter ratio was under analyze but I don't know if finally it was decided or not to develop it
longer axis was expected in order to facilitate the crank fitting (strangely current Schlumpf axis is shorter than KH hub and needs to file the frame)
real anti-rotation system was expected (KH frame is compatible since disc tab is added)
recently I heard of a longer axis (125mm instead of 100mm) to receive the disc brake on the hub but I don't know if this is realistic or not as all KH gear is using 100mm only !

Damn, shorter ratio and disc compatible? If it happens (when pigs fly) sign me up!

Thanks BB, the shorter ratio would be an interesting option. I suppose we'll just have to wait and see what comes out of Florian's workshop.

As far as I know, the 2014 model is supposed to work with spacers (which are forbidden for the current model) and thus will provide compatibility to Kris' EDB standard (external disc brake). The latest thing I heared about a release date was fourth quarter of 2014.

Many people asked Florian about this new generation and I have heared many things about it, but do not know what is truth and what is wish or fiction. Some say, there will be two versions. Others tell Florian said the hub will be narrower and have a seat for a disc brake rotor. Another change could probably be about torque support (or anti rotation system as you call it).

One guy wrote to Florian and got an answer which I will quote here:

Geheim ist das nicht!

Good morning Martin,

a new hub is under construction and will be available within this year.
New are finesses like more space on the sides between hub and frame (allows mounting it in various frames), the possibility to tighten the cranks against a spacer (the present locking rings are not eligible for this), less weight as well an additional version for 125mm bearing space (Coker).
That's no secret!

with kind regards
Florian
Until now, I have not heared anything about the price.

Sounds like a good update to fit into existing situation, but no new 'extras'.

Bring on the ratio change, my bank account is willing

Ah, but for a downshifting hub to run on my 36er, it would be the ultimate gravel road killer.

I never rode with a Schlumpf hub but I read somewhere that there is some play in the hub making it feel like you're riding with a lose crank. Is this true? and if so is it just when you're beginning your ride or is it like that throughout the ride.

Maybe that's something that will be sorted in the next model.

I think the current gear ratio is fine for the medium sized wheels 24, 26, 29, but on 36er a 1:1.33 ratio might be preferable. I wonder has Florian done any market research on peoples preferred gear ratio.

It would be interesting to see what ratio would be most popular with riders on this forum.

I'm asking all these questions because I'm considering buying a Schlumpf hub when the next batch comes on the market

My wallet is holding out the white flag as I speak lol!

There's definitely *some* slop, but it's hardly noticeable, and only while mounting that I could feel.

If there's a smaller ratio and disc compatibility, I'll seriously be thinking about it...

The issue of gear lash comes up from time to time on the general Schlumpf discussion thread (which begins here: http://www.unicyclist.com/forums/showthread.php?t=81914 )
There will always be some, or you wouldn't be able to shift the gears. But in my experience, it isn't that much, and you get used to it fairly quickly. You don't notice it at all when you are pedaling steadlily forward.

Thanks guys, I'll go for it. I intend putting it on my KH 24" first and when I've mastered it then I'll transfer it onto my KH 36er. I'm gonna wait 'til this new model comes out. Hopefully it will be available this year..

Thank you Eric, sounds clear now ! It will solve frame clearance, hub slipping, disc brake compatibility and Oracle frame compatibility issues

Florian said nothing about shorter ratio as Kris told me one year ago, may be not decided finally

Yes, thanks Eric for all the info. The translation of Florian's letter is very helpful.

Perhaps Kris could chime in here... I'm dying to know.
