You may have seen some photos floating around here or there of
Norco's new prototype DH rig, but inside we have one of the main men behind the design giving to give you the lowdown on video. Watch and learn!
Watch the video below to learn more about Norco's prototype DH bike:
Sometimes you see the neatest things while out on a stroll at the river. This is Norco's prototype downhill rig, one of only six in world, just outside of their Port Coquitlam, B.C., headquarters. Norco factory riders have been testing these rigs and design changes for the next round of protos are already in play. Keep in mind that production is still quite a ways off, it could look quite different by the time it's ready for production.
A closer look makes it very clear that the shock isn't floating, but mounted solidly to the main triangle. Yes, from a distance it may resemble other rigs... No, it is not the same and it will have a ride personality all to its own. There are only so many ways to layout a bike, and as designs progress it will be the smallest of margins that will make one stand out from another. Two bikes may share a similar silhouette, but a chain stay being slightly longer on one or a pivot point that differs by just a few millimeters, let alone the angles, will result in massive differences on the trail.
The back of the prototype sports a clean looking Syntace X12 thru-axle system that should be slightly lighter than what has been used in the past. Internal routing for the rear derailleur's shift cable not only keeps it looking orderly, but also prevents the chain from beating on the housing. Like found on all of the other pivots, captive hardware is used to make maintenance easy.
Originally used on road bikes, then BMX before it trickled over to mountain bikes, an integrated seatpost clamp makes for a tidy looking setup. By going this route a keyway on the seat tube is no longer needed, which P.J. says eliminates a weak point inherent to the more traditional design that uses a separate collar.
The prototype uses these smart built in bumpers to prevent damage from the fork's stanchion tubes in the event of a big off. There are a few manufacturers incorporating these into their latest bikes and I'm sure we'll see many more in the future; they certainly make a lot of sense.

Do you like what you see from Norco? Excited for the new machine to hit production? Let's hear what you think - put those thoughts down below!

if you go in my album you will see it, its a redneck quad/skiddoo machine
so if you guys ever see this magazine with my pic in it then let me know
thanks
Gary.

I disagree with you, there are many companies with very strong adjustable frames out there, take the Scott Gambler for example, its one of the most adjustable frames there is! and the bike is strong as nuts. I havn't heard of any stories really of them breaking/cracking, the only time is from over tightening the pinch bolts on the frame, but other than that riding the bike alone its strong. and can be built up very light. On the other hand, that norco looks fairly light and nimble, reminds me of a cross country bike, or like the Session 88 little brother.
i was just using the logic that the guy uses in this vid. www.pinkbike.com/video/157296
but when it comes to insulting a frame with no adjustability, thats just not cool.

Trek session 88
New Kona DH bikes (different name to stab now)
whats special about it? im sure it is probably just made by the same taiwanese people in the same factory, but they have those same taiwanese people putting different stickers on and putting them in differently labelled boxes.
and biggest thing if you are one of the people complaining about colors and how the fork bumpers look ugly, colours are also subject to change. remember people its a prototype.
Kona is and has always been called a "4 Bar Linkage." It's mind blowing wht people call SP's these days when it's the easiest design to spot.
And all these multiple negatives for posts simply expressing a non-consensus opinion...grow up people! Beauty is in the eye of the beholder is it not?
here's a friendly copy/paste text from KONAWORLD:
KONA DUAL SUSPENSION DESIGN FEATURES
Kona Walking Beam 4-Bar Linkage - All Kona dual suspension bikes use a MULTI-pivot 4-bar walking beam suspension. This allows us more options to individually tune the suspension geometry for Cross-Country, Back-Country, Out of Bounds or Downhill
* Compact rear triangle for quick acceleration
* Pivot locations cancel pedaling input on suspension
* Cartridge bearing pivots for ultra plush ride
* High torsional rigidity for ride performance & longer bearing life
* Cold-forged swingarms, dropouts, yokes, headtubes & bottom brackets for high strength & durability
* Custom-tuned rear shocks by Fox Racing Shox
i know it works, but it looks like it (seat stay) would just push into the linkage plate rather than moving it :s
also, doesnt that stanchion look way too big for the body?

Great article explaining what each suspension design implies! Only thing is missing is DW*Link, and Trek Full Floater. From '06.
Trek 88's have Active Braking Pivots.(ABP).
Trek 88's also have full floating shocks.
I.E nothing in common with the new Norco DH Prototype what so ever.Which has actually stuck to the tried and proven FSR system that it's been using for nigh on 15 years.If all the debating in this blog is down to what this rig loox like in sillouette form,then ya could bring Turners into the debate,Rocky Mountains,Ventanas,Azonics and many more quality brands.
At the end of the day this design is nothing new for Norco,their Fluid range and 4xxxx rigs have been doing well using the same tech for years.Let's wait and see what the team/production models can offer before slagging it.But i must admit,the comparisons with Kona and Trek did actually make me laugh,the Treks are much more sophisticated machines,and as for Konas they're single pivot for fcuksake.Makes for funny reading though,so please keep debating away,ya can't beat free entertainment.Ha-ha.
Gringo.
But more importantly it's Sunday tomorrow m8,so we'll both be miles away from car parx and out in the woods.So all is good yeah.

Other than that, it looks like it's designed to last.
the shock is pretty close to the ST which could be a problem for coil shocks with bigger Ti springs. increased derailluer stiffness?? lol
kona is a single pivot. look a the "bottom bar" . it starts from front triangle to rear wheel axle. it looks like a 4bars since the upper bar of the swingarm is floating and pushing on a linker.
Someone else could correct my details cause I'm operating off the top of my head, but I think the basics are there.
Two people coming up with the same suspension design independantly is not inconceivable, and in fact I've seen it happen twice.
Also, Ethos Bikes came up with ICT independently of Ellsworth.
is he canadian?
'it may look similar but its not'
so its not fsr like you said then?!
@Freddiehg, Most, if not all, downhill race bikes have generally rearward axle paths.
not my cup of tea ...
