Still not finished, back pain has turned out to be prolapsed disc, I think I should have bought a zimmer frame as it would get more use
So how many recumbent riders have we?

That's interesting. I vaguely remember reading about a suspension hub before, but I can't recall any details. I'd be interested to hear more about it. Does it make a lot of difference to the comfort?

yep it is a Pantour hub on the rear. Good detective work 
I am in two minds about it, I'm pretty sure that it does provide a minimal amount of suspension to remove some road buzz, but the locknut that holds the sprockets on is a knurled one so impossible to torque properly, I may well have to junk the hub and get it rebuilt with a normal hub, just because of this technical issue. Shame really as the idea is a good one, I have no idea why the locknut is the way it is....there is no doubt a really good reason.
Braking is not the issue as described in the review if your brakes are in the right place as mounted on the VK (in the under bottom bracket configuration) so that the movement of the wheel keeps the rims under the brake pads while in travel.
Pictures and spec of the VK2 here: I should take some pictures of mine at some point because of the non standard spec.

If Carlsberg made recumbents
... but then I am biased.

Hi all, just joined........my bikes are M5 20/20, changed gearing to dual drive hub to clear the front chain ring and tidy the bike up. Like the hub a lot, did cause problems to start, but I changed the internal bearings, junking the cages, and replacing the cottage cheese balls for an engineering quality metal. Needs regular lubricating, but worth a bit of effort. Also Bacchetta 26, pretty much standard other than tyres. Lovely touring bike, can be pretty quick too, but a bit heavy, and I live in a lumpy part of the world. Should I mention the Quest.............

Bit late?
But don't worry we are all pretty laid back about these things

The Quest is a superb machine for flatlands, and rolling hills, not brilliant in West Wales. Had some fantastic tours in NL. Prefered steed at home is the M5, fits in the train easy when you,ve had enough

Haha....too many bikes in the sheds. I forgot the Pashley trike. A strange beast, used almost only when the roads are iced over, or dangerous with mud and leaves. It's very wide, especially compared to the quest, but that enables the seat to be higher, almost as high as the M5. Getting through 'cycle friendly' gates is not funny. Potential to convert it to a 2 wheeler by unbolting the front axle is very tempting, anyone got a spare fork that would fit?

Interesting; would that be a reference to a SRAM Dual-Drive-27/30? I’ve been looking at / thinking about trying one but I shan't bother if it’ s not up to the job .... ?

Hi PP, don't get me wrong, I have four of these Sram Dual Drive hubs on various bikes, and love them, now. They gained a poor reputation early on when they were used on heavy machines like tandems etc, and were geared down too much, resulting in failures. Solo they are fine, so long as you do some simple alterations. Cages are only there for the manufacturing process, and have no mechanical benefit. I see Sturmey Archer make a similar product much cheaper, if anyone has any comments on that.

OK. I assume by 'cages' we're talking about the axle bearings and what you've done is to replace the original caged races with superior quality ball bearings in greater numbers, without the cages? (I haven't studied the service documents for the hub, so I'm just guessing!)
I have an injury to my left hand at present and I was attracted to the DD3-27 because it appears to come with a combined twist-grip sprocket changer and button for the hub, which would enable sole use of the right hand for all changes. Later, when my hand has recovered, I could add a double chainring and a front changer so as to extend considerably the overall gear range on my recumbent trike.

Yes, exactly that, without the cages, there is room for 2 or 3 more balls per side adding to the strength and smoothness of the unit. The changer is a dream. Single handed easy changing, twist for the cassette, and thumb shift for the hub. Brilliant for those rapid stops where you wished you were in a lower gear. The changer is also very easy to set up, and has a simple release devive to enable the rear wheel to be removed and replaced without having to reset the gears.

Ok that's very helpful. Do you know of a reliable supplier of these things?

I bought all mine s/h, a quick look on ebay showed this complete kit...http://www.ebay.co.uk/itm/Dual-Driv...sure_cycling_bikeparts_SR&hash=item5b03aaf241, but as far as reliable seller goes.who knows.
