Hi, relative newbie to this forum.

I purchased a B2C hub and Alex DM18 20 rim towards building a new wheel on a (formerly single speed) Swobo Folsom. LBS did the work building the wheel and installing. Total cost ~$145 parts/labor. Kept the old wheel as a spare (reused rear cog).

The hub works pretty well so far. I think its pretty easy to shift without engaging the brake though I have to plan ahead a bit at a stoplight to restart in LO.

With my 42t/18t cogs the hub runs at about 60 and 83 gear inches for low/hi gear. The 60 gear inches is fine for gentle hills, though I might change to 20t rear cog if my knees start protesting... Certainly the high gear makes the Folsom scoot right along - its fun pushing 20mph on a fat tire oversize BMX bike!

Will keep you posted as to the hubs performance through this winter.

Is everyone getting this clicking sound when braking? Does it go away with break-in? I am on mine, but haven't put many miles on it yet.

Yeah, I get noise when I brake also. It sounds like metal straining. I'm guessing that it's the newness of the brake drum, or not enough grease there. I don't know for sure. Like you, I'm hoping it'll break in over time. If it doesn't quit in a few months, I'll take it apart and find out the cause.

I'm loving the hub otherwise, though.

Not a folder:







Da hub:


Got it with an 18t sprocket, but changed to a 21. 44/21 gearing works out to about 56/75

OK, so a front brake isn't strictly necessary with the coaster brake, but I have some experience with higher pressure, narrower tires and coaster brakes, so I wanted a front brake, was interested in the new 90mm S/A hubs, and really, really wanted to run it through the headset. Result is I could do barspins... if I knew how. Practically speaking, however, nothing on the front runs into any part of the frame:


Fun, fun bike. If you get a chance, try out a S2C bike or build one up on your own. Custom wheel like I built--S2C hub

Finally picked up my Moulton TSR-2 yesterday and test-rode it for about 10 miles. I found two peculiar issues about the S2C on the bike: There was constant clicking noise in either gears when pedaling (not sure about coasting; couldn't hear anything over the freewheel clicking), and black grease kept oozing from the seam between hub shell and left cap. The grease even got on the spokes and rim due to the force of wheel rotation. After a thorough cleaning, more grease came out. Are these problems temporary and normal for a new S2C?

I have a TSR2 as well. Basically the S2C it is both a little stiff and oozes black grease when you first get it. However do not worry after about 100 miles things really start to free up and the grease oozing ceases.

I agree though the S2C is a little noisey. Again I suspect this will reduce as it all beds in.

I am loving my TSR2.

Mine emits the same gentle clicking sound. I'm at about 80 miles since purchase (Chicago weather having precluded much riding). So, listen to Brother Jerry. All will be right soon.

I had the same concerns when I first laced up my S2C in September of last year. Now, she is quiet and running smoothly.

Thanks everyone for sharing your experience. I guess I just need to ride more and break it in.

Anyone knows where to buy the dust cap (HSL921)? I couldn't find any websites selling it. Is it wise riding without one?

Get hold of Sturmey Archer in California and they will let you know what parts are available.

Wanted to pop in on grease boilout issues;

We've built about 25 sets with the S2C recently, and stuff is going pretty well.

Couple folks complained about this. All but one of the hubs seems to have settled down with extended (100+ mile riding)

Excited to see how these hubs hold up to their original duomatic fame!

I have an original Duomatic hub and the new S2C hub (since September). The S2C is very impressive. Biggest improvement is in the braking. The Duo brake does not inspire confidence at all, and I would never dream of riding one without a front brake. OTOH, the S2C's braking is very solid. I can easily lock up the rear wheel if I'm not paying attention.

A nice comparison of the two can be found here: http://www.moultonbuzz.com/2011/02/s...er-s2c-review/ . I basically agree with their findings.

Hi all,

Any thoughts on whether a similar gear ratio provides comparable performance on a folder and a full-size non-folder?

I have a 2-speed Brompton (133%, 4.45m - 5.93m) and was thinking of getting a bike with the 2C (138% - http://www.achielle.be/EN/samsaar.php) for days I don't have to fold.

Is it safe to assume that anything I currently tackle on the Brompton will be equally "tackle-able" with the full-size bike?

Thanks!
Pat

I am still not certain if my S2C hub has worn in yet. I have done about 150 miles and although only a little bit of oil/grease is still oozing out it does rumble a little when pedaling in the higher +38% gear ?

I am definately getting use to it especially the need to have your foot in the right position when stopping ready to take off again, but sometimes I find it also changes gear when I go over a bump or I jolt a little ?

Sometimes it refuses to change gear until I pedal back a few time to hear that defining "click" ?

Also sometimes I almost feel a little click/slip as it changes gear when setting off again ?

Maybe I'm being paranoid

Regards

Jerry

S2C - A mixed bag?

I've used the s2c as a replacement of a f&s 3-speed on my cohabitant's dutch bike, so far it's done about 130 km. Sadly, the experience with the hub has not been without issues.
1. Firstly, the hub looks ace, kickback-shifting is fun and much easier than anticipated. The range is so huge the use of a big cog, e.g. 22 or more, is not unreasonable, especially for a lady's bike! (700c/44 blade/22 cog). Also, it really is a heavy piece of kit!
2. FWIW, the hub is next to inaudible in comparison to the torpedo.
3. The s2c is too tightly packed albeit the excess seems to get squeezed out nicely Ours already lost quite a proportion of its initial friction quite probably due to this, though there still is room for better performance…
As to the issues we observed, some of which were already voiced, e.g. by evinem. With the cohabitant's hub there seem to be issues with the adjustment and precision of the hub.
4. Braking forcefully provokes loud ticking and pedal-kickback which is bad for modulation and does not infuse confidence. The brakes perform well enough and are not yet broken in, so I hold my judgment here.
5.The kick-shift into 2nd gear frequently puts the hub in a limbo between 1st and 2nd gear; it then takes about half a revolution of forward-pedaling in 1st gear until suddenly the 2nd gear kicks in.

This seems to be a (worse?) variant of that same behaviour and constitutes the main complaint I have atm. Not sure how it can be resolved.
6. It is possible to lock the hub while backwheeling. This might be related to the aforementioned limbo-state and could be resolved with gentle forward-backward turning of wheel and pedals. I strongly suspect the hub can be damaged in this state with too much force applied. I'm not exactly sure whether this is a problem of the coaster brakes though.
7. Lastly, coasting at higher speeds frequently causes involuntary gear changes. This happens even when the rider takes care not to make back-pedaling motions. I assume this also is due to the relatively high internal friction of a new and excessively packed hub, so it might be premature to judge on that one.
TL,DR: Looks ace, is a tad heavy, operation is easy, but not sure whether its precision is as good as it should. Those are the problems with mail-ordered fringe products, I guess.

Since that post I am now up to about 300 miles and things have really settled down.

Consistant changing has been possible since I changed my technique as follows:

I take the cranks horizontal and stop pedaling then move the cranks slightly
forward and then back to change. I have tried this on the bike in my work stand
by hand and it changes every time. Then taking it out on the road once I got my
legs set up to do the same thing, it now works a treat.

I don't think it matters where the cranks are, the trick seems to be the very slight foward movement after you stop pedaling and then you can back pedal and change every time!

This hub certainly takes a while to settle down and need wearing in but I am pleased with it now.

Regards

Jerry

Am I understanding this right? You're referring to the S2C on a Brompton? I'm picking my first one up soon but this sounds like a future mod - no cables to the rear and one lever. If this is a Brompton, how does the coaster brake function with the chain tensioner? Any chance you'd post a pic?

My S2C hub, which is now 9 months old, has mysteriously locked up on me. It's done it twice. I haven't been able to figure why it locks up and why it suddenly unlocks. It's a little worrisome.

Great hub otherwise. After the initial settling in period, I've enjoyed this hub tremendously. Hope this locking up habit doesn't persist. If it does, there's a SRAM Automatic hub waiting in the wings to replace it....

I have built 700cc wheel with S2C hub for my homemade bike/commuter. It has all the same symptoms as described here. Lots of grease coming out of hub and it makes really annoying noise and clicking when both braking and pedaling in high gear. I contacted Sturmey Archer and they said that some hubs were not machined properly, here is the quote from reply:
"We had some hubs have an issue with the brake surface not being fully polished so when braking it would make clicking, popping, sounds. But I have never heard any complaints about abnormal clicking in second just while pedaling along. If the clicking is happening under braking load I would replace your hub for you. I just need to know the color and hole drilling and a good shipping address."
so it looks like there should not be any sound to start with. I have already made more than 100km for sure and the hub only sounds worse. My concern is it will brake somewhere in the middle of my commute, which is 18km one way. So I will probably go ahead a rebuild a wheel with a new hub if they send it to me. It also ceased a few times to the point when the wheel was locked completely. Considering the weight of the hub I'd expect it to be bulletproof and reliable. So far it is not. I am thinking about eventually switching to shimano nexus if this keeps going on.

My S2C locked up on me twice as well. Not cool. Mine is from one of the earliest productions and hopefully SA has improved it since.

One additional note: A few times my S2C got stuck in the high or low gear. I had to kept riding and braking to somehow bring the shifting ability back. Perhaps mine is an isolated case, or I simply don't know how to ride it "properly." Either way it isn't reliable enough to put my life on it. I'm getting a new hub.

I know it's not a folding bike, but if anyones interested, here is a pic of my red 32H S2C (laced into a 26" Sun Ringle Rhyno Lite XL rim with a fat frank tyre) that i'm putting on a Pashley Trade Bike. The front hub is a SA HBT.
