Cannondale have always done things differently. They have never simply accepted the conventional logic, preferring to walk their own path for bike design. At their team camp in Finale Ligure in Northern Italy last month they had this beauty of a downhill bike out on display - David Vasquez's World Cup downhill race bike, circa 1998. Identical bikes were also piloted by Missy Giove and Anne-Caroline Chausson. The engineers behind this bike were clearly pushing the envelope of what was known and possible with these bikes, it also shows how far bike design has come since then in some ways, and hasn't changed much at all in others. We take a closer look...
First off: geometry. That's pretty slack and the chainstays looks pretty short, but for a modern bike that BB is way high. And yes, it's not what you'd call light.
What the hell? That's the first thing people usually say when they see the crank/drive arrangement. Like everything Cannondale did with this bike, there's a reason for it though and a singularity of focus you don't find too often. Look at those linkages for the suspension, do they look familiar? They should, as Santa Cruz and Intense (
who license the design from Santa Cruz) use a variation of them for their VPP bikes today. Cannondale's engineers optimised the linkage to work with a specific chairing size, a larger or smaller ring would affect the performance, but their racers still wanted to be able to change their gear ratios to suit different courses, so this system was developed to keep that size constant.
There are five rings in all, but it is the ring on the non-drive side crank that drives the system, in the same way that the chainring(s) do on the bike sitting there in your garage. That power is then transferred by the first chain up to the sprocket sitting forwards and above it. A fixed axle transfers that power through to the sprocket on the driveside and a chain connects that to another sprocket sitting behind the larger driveside chainring. There is then a system similar to a freehub engagement to turn the main chainring as it is not directly attached to the crank arm. To adjust the gear ratios the team mechanics could change the size of those four sprockets driving the chainring - although it wasn't too popular with them as it was so complicated.
The "Super Downhill Moto Fork." What a name. Essentially it is two modern Lefty forks, bolted together at the crown.That means each leg has a complete, separate damping system. You can't see it because of the boots, but they don't use a round tube, like modern stanchions, instead they are square and use needle bearings instead of bushings. For this length of fork, Cannondale felt that the twisting forces from compression and braking compromised the kind of bushings every major manufacturer uses today and meant a loss of performance. This system of square tubing and needle bearings completely separates the vertical movement of the fork from the forces acting on it.
The idea of adjusting geometry at the headtube is nothing new - here you can see offsets in the headtube to help slacken out that headangle. They are custom-machined eccentric cups for the headset bearings to sit in to give a couple of degrees of adjustment. It's also worth noting the size of that headtube - Cannondale invented the 1.5" headtube as they realised the larger area meant they could build their frames much stronger. On this bike the fork uses a 1 1/8" steerer, which gave them the room for the offsets.
While some of the bike was well ahead of its time - the rear axle still had some way to go, as nobody had started using burly through axles at this time - that came with the next generation of their bikes.

kids, seems that we are all brainwashed
Mah, forget it, when DirtTV went around pits and measured the weights of top pro DH bikes ending up with numbers around 38lbs, that still didn't stop weight weenies from going for the quest for sub 30lbs DH bike
I'd personally like to see a writeup on the Sunn DH bikes. Always liked those...
Sounds pretty innovative to me. It's a shame they had to sell themselves and stopped producing race bikes like this.
They had some other "questionable" firsts too... the two-shock DH rig was pretty awful, and they didn't earn the name "Crack'nFail" for nothing (this has NOTHING to do with their current bikes, only that when there weren't really any real "FR/DH bikes" being made "back in the day" and people were abusing XC bikes at the begining of our sport and Cannondale's weren't up to this... lots of tothers weren't either. They also had some bad luck early on with teir "real" Fr bikes not being up to the task of sustained abuse without sponsorship). I'm just bummed to see Cannondale COMPETELY dismiss our whole riding acene. The Claymore is great and all, but it's not real an FR or a DH bike, it's like they've only designed bikes now for the riders they sponsor... Chase doesn't want something a little burlier then the CLaymore??? I know he loves his HTs
Those tires are IRC Kujo DH (named after a film about a rabid dog). At the time these tires were the muts nuts - they have a very good pinch-flat resistent sidewall. It wasn't long after that the Maxxis Minions and High Rollers came along and their reign at the top continues to this day.
From the looks of it, those rims are a set of Mavic 321s, which were also the top DH rim of the day until the yellow DeeMax rims came out.
All in all, this bike was blinged out.
Those Kujo's never compared to their older Missile's which just seemed to be a much nicer tyre.
No matter what people say, Cannondale have had a huge influence in the sport as we see it today.
Only this week I've found a home for my 321s on a friend's original Foes Mono DHS that is being built mid-school (I would call the Weasel Old School). I can't wait to build them up on the old Hope hubs I also couldn't throw out.
The bike companies were racing prototypes. I know they still do today. But we can get hold of the kit they use within a year or two.
That's what I like about the scene today.
You can go out and buy a Giant, Yeti, Mondraker, Santa Cruz, Kona, Trek, Commencal, Specialized, Nuke Proof or whatever
and you know that apart from a few small changes (bit of geo, shocks, colours) its what all the pro's use. FACTORY STOCK.
Back in the day there were little-to-no DH bikes ready off the rack - you bought a frame, forks, brakes, drivetrain etc separately and bolted it all together. And here in Australia that could cost $8-12k. Full-on DH was seen as a tiny market. Only serious racers had such bikes.
Nowadays, every ski resort is a bike park and forests are full of stunts and the Giant Glory 2 is $3000 and lighter, stronger, and better in every way than anything from back in the day. It's not just a quarter of the price, but taking inflation into consideration it is like a sixth of the price. The top Glory is only $5k - an absolute bargain.
Their Karpiel Disco Volante was certainly out in 1997.
'Dale weren't the only guys to be fiddling with designs like this back then
Outland had bikes and patents dating before then and the LOOK bike with Fournales air shock with near identical links was out around this time as well (Jean-Pierre Fournales patented the frame design)- I'd have to do some research to see whose patents came first and exactly what they entail. There were also other twin link bikes like the RockShox LTD that Trevor Harris designed (completely different function though.)
Every DW-link bike from Turner and Pivot has a lower link that switches rotation direction. VPP is less about the links and more about how the suspension behaves.

Then Azonic had a vpp frame , it was a brazed cro,mo . 97 Karpil VRS and then in 98 the cdale came out with the fulcrum.
the vpp was designed in Calgary , in your home town PB.
also the intense vpp was worked on by another calgary dude.
Cow town produced some tallent ( who remembers COGG'S) back in the day , way before DW was riding a bike .
And I remember Cannondale putting electronics on their bikes - I think it was so that the suspension could 'learn' the course, and get softer or stiffer depending on which part of the course it was on - e.g. it would get really stiff during pedalling sections. Memory is hazy, but they did put telemetry gear on their bikes at one stage.
I remember this being on the old K2 bikes but not the Cannondale...it was called the "Smart Shock." Took a 9V battery. Ha

Also every friday, Old school post!
i could be wrong my memorys not too good nowerdays
I recently picked up a pair of the old DH pants that Missy & Myles used to wear; the red/yellow ones, perfect condition, on ebay for .99
Schwwweeet
Now if I only still had my old red/yellow Super V
In Miles' and Missy's day didn't they wear skinsuits? You know, back in the day when speed was more important than looks.

But do have GT LTS & ATX one
Way ahead of their time
Yamaha just Introduced cannondales " airbox in the front" concept this year
Too bad
So close but no cigar
