This frame is actually being planned for mass production. Last update I heard from that was early fall.. and I'm pretty sure the bike pictured was made via production tooling. If you are interested Rob Metz and James Dodds have a mailing list:
rob@fluidtrails.co.nz

Derek made that frame/gearbox as part of his grad research. I'm sure he is still working on it. He is a member of these forums too: Nately27
It does look like his website is down however :(

i was referring to you comparing Nicos World Champs Vprocess to an Intense Uzzi DH (which was of course from the same era but totally different suspension system)

seeing the golden Vprocess was bringing back some memories for me which have nothing to do with an Uzzi DH :)

thats what im guessing too. they had a tank of nitrogen on hand when it was tested, so im guessing it was a standard air type shock using nitrogen as the spring, wrapped up in the smoke and mirrors of "technology that is used on tanks" etc
I'm not so sure. From their description - assuming it's accurate - I think what's more likely is that it had some kind of combined/parallel spring and damper unit, whereby a hard hit would increase the rebound damping somehow, and/or reduce the spring force during extension. IIRC Push had a kind of similar thing that they called "frequency sensitive damping" for some of their fork kits, whether or not that ever made it to production I don't know, and I think it actually worked in exactly the reverse manner to what I'm speculating with the Millyard shock (harder hit = rebound circuit opens up more). However, if this is the case - and it's purely speculation - I find it pretty hard to believe that Millyard managed to tune it all that well on their first attempt. It increases the number of tuning parameters quite substantially.

No, trust, the millyard shock is king, when they say tank technology, millyard himself worked on the suspension designs for challenger 2 tanks, he can use the technology because he is cleared to, thats why nobody else it allowed inside, having SEEN the bike, its a masterpiece, ****ing nuts bike, unlike alot of hyped up things, this is genuine.

The Millyard bike does have some interesting innovations (aside from the shock, which apparently may or may not have worked as well as they say).

The completely internal drivetrain is a pretty cool feature and does seem to give the rear wheel much more clearance. I wonder how that worked out in practice though.

Anyway, moving right along, a friend of mine sent me this picture a while ago. Anybody know anything about this? I'm assuming it was never brought to production or anything.

Millyard himself didn't design the shock, it was some friend of his. I've seen the bike too, as well as briefly spoken to Allen Millyard at the 07 Worlds, and he didn't really seem to know a whole lot about exactly how it worked - his explanation was that it had an "exponential curve" (spring? damper? compression? rebound? what?). I was more impressed by the sealed drivetrain (despite the fact that it would have to pedal pretty badly) to be honest. I think it's a genuinely INNOVATIVE bike but I don't think it's necessarily genuinely "better" - Allen struck me as somewhat full of it at the time, but I only spoke to him for 5 mins. Only a handful of people have ridden it, and while Steve Jones obviously loved it, the anonymous French rider didn't appear to be overwhelmed by its sheer awesomeness. Tank technology - so what? Tanks don't even have wheels for starters, I really couldn't care less how my suspension works while I'm riding over landmines since most race courses outside Cambodia seem strangely devoid of such obstacles.

Regardless, I'd love to see more from them, and I'd like to ride one of those if given half a chance.

They say it uses technology from Chieftain tanks...if you look up chieftan tanks, they use Horstman hydragas suspension Chieftain tank - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Question_book-new.svg" class="image"><img alt="Question book-new.svg" src="http://upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png"@@AMEPARAM@@en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png. Hydragas shocks are an evolution of the hydroelastic suspension used on minis and rovers of the time. Better than a coil over oil shock? Ask people who race minis. Maybe that's not it, but if you look at the shock body, it seems possible/likely to fit it in there.I find it hard to believe that technology brings anything new or better to the table, and the last people I want working with anything that contains oil on my bike are the british....

Ive rode with Derek in the past. Seems he has it on the back-burner as of now with school sucking up a majority of his time.
that's too bad. The CVT was kind of neat, but I loved the way the frame looked. IMO the perfect design for a DH frame. Low, tucked away, no excess flash, vertical post, good pivot point... That bike would be great with a gboxx or even an idler and standard gear setup. Hope he does well.

Wasn't the suspension based on challenger? Totally different beast to chieften. Challengers are fearsome, you've gotta see it in person to believe how quick they can move cross country, there is very little chassis movement and the suspension just swallows everything up. Who knows if the tech is suited to a mountain bike application tho, Dirt seems to think so but I'll hold off 'till I try it.

The workings and technical details of this shock are currently classified with technology information that has arisen from the Ministry of Defence (MOD) workings on Chieftan tanks, if I told you I’d have to kill you all! The shock becomes incredibly hot during riding so a “Do not touch” sticker should be applied!

Peanut butter?

My bad, I'd never re-read it and was just going off memory!

Never seen an Abrams in action, been in a few MLRS tho (which is based on Abram chassis I think) and they are rediculously fast cross country 'cos there so light weight (respectively)!

Sorry for the tank talk :p back to posting pics of cool old bikes!

It was at the Mountain Cycle booth at interbike, no idea what else was behind it, but I suspect it was simply a concept bike.

Haha check out the name of the bike!! Why would you name a bike the bloody "slog dh" when it looks like it's gonna be a pain in tha ass already!!

I was thinking the same thing.... Nico and Peaty at world champs..

I was reading the article on Sicklines about their SSO project build and there's some really interesting stuff in the interview with DW that's part of the article. I was searching for some pictures of some of the stuff that he mentioned and came across this:



2005 or 2006 DHR frame with round tubing. Never knew this existed.

The DW interview also mentions that for Sea Otter 2005, Rockshox had created a 6" travel air sprung boxxer that was supposed to go on the SSO, but ended up being used for Nathan Rennie's Nomad. Never seen or heard about this, does anyone have a picture?

Also appreciated would be any pics of one-off/proto/team only DH stuff. I know there's a bunch of industry folks that post on here that have some interesting stuff on those harddrives...
Haha. Thats one of my teams bikes. Actually its my wife Ankas Bike. It was later stolen that year by some quebexicans at Mt St Anne. So if anyone sees it pop up let us know :-) It also had the 1 1/8 headtube, Bailey and Kirkaldie also rode this model that same year. Push modded our Fox DHX and had a remote reservoir set up for us well before fox offered it for Turners and a few other frames with fitment issues. The year before we also had some "one off" pushed boXXers with anno red stanchions.
There are still lots of little one off tricks you will find in the pits at world cups, some public, some not, but you just have to know what to look for....

do most teams open up to photogs like yourself about this kind of stuff and ask to keep it on the DL?

I remember seeing a few of those Fox DHX remotes on the Maxxis M1's back in 2002 or 2003 before the team went to Turner.

Donny - I have pics of these Boxxers! I always thought these were the ones done by Romic (with the "Romic Trick Fix" to prevent cavitation and pressure build-up), no?

Are these the ones you're referring too? They look sweet!
Yup - those are the ones!
