United Bicycle Supply will be carrying the S2C in silver, black, red, blue, and gold.
Quality Bicycle Products has both the S2C in silver and the B2C Steel shelled version of the S2C.
The Merry Sales is carrying the S2C in silver.
These are all distributors who will sell to your local shop but DO NOT sell directly to consumers so please do not contact them directly unless you are an authorized bike shop.
The S2 is just around the corner. This hub should be available in September. Any questions please e-mail me or leave a comment.

I wish these beauties were more easy to come by in Germany. Get distributin', guys, and see you at Eurobike!
which gear is direct drive? the low or the high?
great work on those hubs!
Just fitted one to an old Moulton MK3. First impressions are good. They come shipped quite tight, but it is loosening up now. Thanks for giving us this new product!
The low gear is direct and then number two is 38% above. So 138% overall.
The hub I received was also very tight. Freewheeling is ok, though. I'm hesitant to build up the wheel thinking I may have got a bad unit. Are there any adjustments to loosen it up? I couldn't find anything on the SA site.
Can you let me know if there is any limitations with respect to single gear ratios? I am currently running a 42 chainring with a 16 rear cog. Will the sc2 work fine with this combination? I have heard it may cause binding unless fitted with a 2:1 gear ratio.
Thanks
The hubs ship tight from the factory to compensate for the shifting and loosening that occurs when they travel over the ocean to North America. You can either adjust the cones or ride the hub and the cones will break in in just a few rides.
M&S&O: 42 x 16 should be fine.
Where can a person purchase these hubs? haven't come across anything on web for sellers.
Would be nice if your front drum/dynohubs were also available in anodized colors.
Where can I find the following information?
Flange diameter
NDS center to flange
DS center to flange
Thanks
Hi,
Lookiung at buying the S2, but how do I fit these hubs to an existing standard wheel. Can I shorten the spokes, or do I need to buy a new wheel.
Thanks

Well, my silver S2C just arrived at my LBS here in Brooklyn, NY. Can't wait to get a new wheel built up around this. I've been waiting a LONG time for someone to get hip to this type of hub (My old Sachs Torpedo is about shot, and I'm glad S-A took the hint. Will report on the new build when I've gotten some miles in.
Is the freewheel version available yet?
Any idea when the kickback S2 in silver, without the coaster brake, is likely to be available in the UK market channel. I've got a project just begging from one of these little beauties...
The ship date for the freewheel version of the Duomatic has been delayed again. Two questions, please:
1)What is that hub's current ETA?
2)Can I roll a 48/16 ring/cog combination?
TIA. I can't hardly wait.
it makes sense to combine the coaster brake version with a drum brake hub up front. However unfortunately you do not offer a front drum brake in annodized colors to match the color S2C hubs.
It would be great to have a drum-brake version of the kick-back hub.
Sorry for the delay in response to all the questions.
In this article it says where to purchase the hubs through. Just let your local bike shops know which distributors are stocking them.
Front Dyno and Drum hubs unfortunately cannot be anodized. Because they are forgings the only option would be painting and there is no way we would be able to match anodize with paint.
Currently we do not have the wheel building specs up, so for the time being you will have to break out the trusty ole calipers.
Fitting the S2 into an existing wheelset will have to be performed by an experienced wheel builder or bikeshop. You will more than likely need new spokes and nipples.
The S2 freewheel version is currently on the way to most of our distributors. United Bicycle Supply here in the US will be one of the first to receive them. Should be early December as they shipped the beginning of this month.
S2 in the UK you should contact info@sunrace.nl. That is our European office and they will be better than I at answering that question.
48 / 16 is no problem for the S2.
Thanks for all the interest guys and if there are any other questions please do not hesitate to post.
Well, it's only been 12 hours since the new rear wheel with the S2C hub was installed on FauxFix, and I got a wee bit of riding in on it before having to dash off to other urgent stuff.
Here's what i can tell you so far:
- The thing rolls smooth. Pedaling and coasting is nice, and the ratcheting sound while coasting is pleasantly soft, wheras my ragged old Sachs Torpedo was eratically loud (likely the result of badly-worn bearings, pawls, et cetera).
- Smooth and sure high/low shifting; having a purely shift-on-demand hub might take a little getting used to after leaving behind the automatic Sachs, but the one thing that won't require adjusting to is the ability to sprint uphill without dreading an untimely–and unwanted–upshift at the worst possible time.
- Perhaps the only (small) disadvantage of pure shift-on-demand versus the Sachs hub'd auto-shift is that, when you come to a stop via the coaster brake, what gear your start off again in depends on the dear you were in before stopping. With the Torpedo, after stopping with the coaster brake, you always start in low gear, whether you were in high or low gear before stopping; With the S2C, if you stop while in a low gear, you'll start off again in high gear, and vice-versa. For me, this is a tradeoff I can easily live with, and adjust for (and likely impossible to avoid without some rather complicated engineering).
- Its diameter is somewhat larger than the Sachs, although, once built up and on the bike, it's hard to tell.
- It's a tad heavier than the Sachs. But I'm also running 36 spokes instead of the 28 the Sachs wheel-build required.
- It's well worth the (quite reasonable) cost.
- It's pretty in silver!
- If there's any justice in the world, this hub should sell like crazy. (Think of all the burned-out fixie hipsters out there, for starters!)
Bring on winter. I'm ready.

A little more riding, and the hub becomes more impressive. A little review, plus a few pictures, are here:

si son preciosos pero no hay manera de encontrarlos en Europa, no al menos en tiendas en la red
Anonymous: For Europe if you are having a hard time finding the S2C please e-mail our European office directly at info@sunrace.nl. They should be able to point you toward a distributor that sells in your local network of shops.
