"About 90 quid, I'd guess."

Well, I'll put a tenner in a pot if nine others will - winner gets the hub! On condition that installs and tests within 12 weeks!

Make it a fiver and I'm in.

Mind you, if it's built into a 700c wheel with 120mm spacing, lots of people could try it out. Just need the SA top tube clip-on fulcrum and guide pulley to fit it onto any fixie or 5-speed bike.

So to resurrect this topic, any got one or know anyone who has got one?

There's a thread on the CTC forum - they're not in the UK yet, but Derek at Old Bike Trader has ordered 10 of them from SA. I think he'll be surprised how fast they disappear.

Want one!!!!!

Haven't got a bike it'll fit (yet). But I really do want one!!!

oncemore · « **Reply #55 on:** 13 June, 2009, 04:31:06 pm »

IF less than a 100 quid and IF I can source one, then I'll get one (I'm really missing fixed after 4 months, with "variable" I'd start again!). But I rather suspect price will be nearer 2 than 1 ton.

I don't see why it would cost more to make than an S-RF3 (£40 if you look in the right place), so they're milking it if it's £200.

Hype? Supply less than demand?

Development cost, specialised parts and their associated tooling and much smaller production figures would all justify a larger per unit cost.

Our senior club member's recollections of the slackness of the original hub, so that it was always as if the chain was slack, and the ability to find a false neutral between the gears, would put me off the idea. Will the new one be better made?

Maybe. But a new AR (a complicated dual-epicyclic hub sold in tiny numbers to time triallists) used to cost only about 20% more than the simple AW introduced shortly afterwards, which is probably not much more than the extra it cost to make. I don't have a comparative cost for the ASC, because that was introduced about 10 years later, with a war in between.

There's the reason why the original Sturmey went bust. Brooks was part of the same company, and look what's happened to their pricing.

rogerzilla · « **Reply #62 on:** 20 June, 2009, 12:16:43 pm »

I think the UK/US fashion for derailleurs, which deliver far more speeds with barely any efficiency loss*, was the problem. MTB was the other - SA couldn't deliver the kind of gear range required.

Technically Sturmey didn't go bust - they were the victim of a highly leveraged buyout by Lenark which went wrong. The Taiwanese have done a pretty good job with the brand (and designs) so far.

*generally, hub gears with lots of speeds are pretty inefficient; the SRAM 7 speed is quite clever as it only ever uses one planetary geartrain (three suns, three-stage compound planets, one gear ring), but some of them use three planetary stages in series, and each one saps 3-5% of power.

We've just had an ASC donated.

Gonna bung it on ebay

Do you have the shifter?

I'm not interested, by the way.

clarion · « **Reply #65 on:** 26 June, 2009, 06:03:31 pm »

It's not on there yet.

Not that I'm interested, either...

Hilldodger · « **Reply #66 on:** 26 June, 2009, 08:14:08 pm »

Yes, we do have the shifter.

Not that you are interested

clarion · « **Reply #67 on:** 26 June, 2009, 08:38:49 pm »

Oh good. I mean, for whoever might want it, that is. But it's still not on there...

rogerzilla · « **Reply #68 on:** 26 June, 2009, 08:46:08 pm »

I'd rather have an AC (non fixed, ultra-close ratio) than an ASC The ASC has top gear as direct drive (like the new S3X) which wouldn't suit what I'd want to do with it.

No, we won't list it for a few week because we want to try it first.

I'll mention on here that we're listing so you can not bother to keep an eye on it

Whatever will they think of next ?

If they could find a way to let you stop pedalling when you are moving - like when you go down steep hills - it would be nearly perfect.

We have one as well, we had a bloke track us down all the way from Switzerland but the sale fell through when someone who shall remain nameless did not bother to post it on time.
