You're looking at the 2011 Marin Quad DH. If you've been paying attention you'll know that this machine has been in the works for awhile, over four years of tweaking and fine tuning! Many changes have been made as the design has gone through the prototype process to finally end up with this polished DH bike. The Quad DH retains the 10" of rear wheel travel that the proto's used, but gets some geometry adjustments in the form of an even lower bottom bracket and a slack 64 degree head angle. Oh yeah, it's lighter as well! The bike is available right now.

Curious as to what is going on here? This is Marin's Quad Link suspension, the same design as found on their other full suspension bikes, but tweaked to control the Quad DH's 10
Curious as to what is going on here? This is Marin's Quad Link suspension, the same design as found on their other full suspension bikes, but tweaked to control the Quad DH's 10" of travel. The two short links, Marin has named them "Quick Links", create a virtual pivot point out in space that the swingarm rotates around. But it gets cooler: the actual location of the virtual pivot changes depending on where the bike is in it's travel, letting it behave differently depending on the terrain and needs of the rider. The goal is to make a bike that absolutely eats square edge bumps and carries speed through the chunder very well, but can still pedal out of a corner with the best of them.

Burlyness. This is one very solid looking bike. Yes, this frame is lighter than the prototype version, but eying up the Quad DH tells me that this should also be one hell of a sturdy ride. Marin is so confident in their stiffness and ability to protect the pivot bearings that their bikes come with a lifetime warranty on all bearings - impressive! I'm currently testing this bike's little brother, the Attack Trail 6.9, and it has to be one of the most rock solid all-mountain bikes that I've ever beat on.

The de rigueur tapered headtube. Say what you will, but tapered headtubes make enough sense that they are quickly becoming standard on the front of everything from DH bikes to trail bikes, and even some XC machines. Strong, stiff, and light, its called progress people! The Quad DH uses an integrated headset to keep things low. Love the headtube badge!

The Quad DH's dropouts are both replaceable just in case disaster strikes. Of course the rear end measures in at 12 x 150mm to keep everything as stiff as possible. The cyan color of the Quad DH that you see here is actually the same as was used as the 1991 on their Team model. This being their 25th anniversary, the color was brought back on the Quad DH, the Pine Mountain 29'er, and Andrew Taylor's DJ bike, the Alcatraz.

Shaums' race rocket is looked after by Fox suspension all around, with his fork sporting a 2011 cartridge and the rear of the bike controlled by an RC4. If you have yet to try the Kenda Excavator tires that you see on both ends of his Quad DH, you owe it to yourself to have a go on them. I've spent lots of time on both the 2.5

If you have yet to try the Kenda Excavator tires that you see on both ends of his Quad DH, you owe it to yourself to have a go on them. I've spent lots of time on both the 2.5" and 2.3" sizes and have been amazed with how predictable they are. You'll also be pumped to know that they cost less than most other high end rubber.

You won't find any of those
You won't find any of those "new" old neon green or purple colors anywhere on Shaums' bike. Gold Race Face Atlas cranks match his gold hub and rim combo... which matches the chainguide hardware. Plenty of show, but plenty of go as well!

 gotta love all the brand biggots , if it aint got santacruz or intense written on it it gets dissmissed as garbage, how many of you have actually ridden it?? as far as you know it could be the best handling bike on the planet . remember it wasn't long ago that demo 8's were old crap bikes , put sam hill on one and suddenly their amazing and all the kiddies want one .

 How true! A few seasons back I reviewed a DH bike from a brand that can be found in some sporting goods stores (not that I'm saying that that is where you'd find a Marin!) and it is still my all time favorite DH bike. It was/is so inexpensive when compared to other brands that it was shocking, but I'd pick it over pretty much any exotic dream bike that I can think of. Lesson learned: Never ever judge a bike by how it looks or by what other people may say about it.

 Marins are not cheap bikes, definitively not. I tried one last year at the US open and they're awesome bikes

 If its about my response - dont like SC and Intense either. Also guilty of much marketing BS and the susp is not as amazing as they claim. Also demos were never crap, a bit funky geo in the pre hill ones but still they were not bad.
  • 1 2
 i had a fully specced demo for sale (see profile) and it was only after Hill swung his leg over one that i got any interest, until then they were deemed 'collective' road gap machines, totally misunderstood. the demo 8 has always been a good bike, they should have stuck to 135mm on the back IMHO
  • 1 2
 Well its only a fault of stupid kids and bad spec marketing(or lack of it).

As for the 135mm - the 150mm is a good move for ppl who change frames and want to keep their wheels.

 Wow the fact that those idiots argued about how similar the bike is to other bikes really makes you wonder about people and how ridiculously dumb it sounds! It's a fantastic looking bike and it's probably going to get you to the bottom of the hill comfortably and safely. Best looking Marin ever!

 Intense got me! all those interesting bike were announced like 2 years ago (dhr, quad dh, gt...) and the only new race frame choice i had this year was the 951. They all blew it as far as i'm concerned because when they announced that a new frame was coming out, i sold my old bike and was stuck without a bike waiting and waitng for this bike after i've demoed LAST YEAR!

 Look at the lines, the rear swing arm, the front triangle, replace the links with rails and move the shock round and you've got yourself a 303.
  • 51 3
 Yup, replace the links with rails (in completely different locations), place the shock on a entirely different spot on the frame... basically make a different bike... and you'd have a 303 =)

 Shred...your comments are ridiculous. Why would you even make that statement?? And don't hide behind the notion that it is 'my opinion'. That doesn't make it any less stupid. I could say this bike looks like a cheeseburger. That's just my opinion guys...Of course you will be neg propped, that's the point of it, so that dumb comments become hidden. Rule is: Don't compare bikes to other bikes unless you at least looked at the other bike...

 Sarcastic, stop hiding behind your fake account. It's pretty obvious from your activity board it's not your real account.

You trollin.

And if you can't see let me explain, the rear triangle is very similar in shape and position to a 303, the 303 is just slightly shorter and lower. As are the lines in the front triangle. Even the brace between the top-tube and down-tube is in the same place, just not kinked as in a 303. Sure there are things different, other wise they'd get sued, but the main lines of the bike are very similar. The Blue colour also helps you see the image of a 303 in that frame. Maybe they did this on purpose? Aesthetics are everything, and a 303 is a pretty good bike to strive to look like.

 I think, Shred, the point is that although this bike and the 303 look similar from a layman's point of view, if you look at the suspension design, there is a big difference and this is the important point which (to a DHer) completely distinguishes the two frames. I mean you could make this distinction if, say, you wanted to discredit the yeti, or marin, or whatever - in a sarcastic manner, but you began by almost calling out Marin for copying - which isn't the case.

This frame has been on the cards for a long time.
Shaums has been rocking it on this bike for many years (well nearly the same frame haha), 2006 and 2007 world masters champion in Praloup that he won on pretty much this bike, 2nd in 2008 when he turned up with only one days practice and race day.

  • 1 0
 Wedding ring? I hope you're kidding, Wedding rings have been used for centuries and they usually have diamonds in them or precious metals. I have never seen a wedding ring with suspension. The only possible way you could be even close is because wedding rings often come with a Chain... but that locked to a ball not a crankset. Schism you should look at more cheeseburgers before you say stuff like that... I am giving you props though, only because your 16 and so you clearly don't understand marriage.

 I just said I thumb up'd you because my opinion was that your opinion was ok... but don't forget that you can loose your right to have an opinion. I am still earning back the right to have my own opinion. I lost it a few years back when I got married, thus my sensitivity over wedding rings. It is also my opinion that Shred and Sarcastic might be married, which is why they both can't have an opinion. Over time they will learn to respect the basic rules of nuptial bliss and they will accept that this cheesburger, wedding ring bike is nice even if it doesn't come with bacon or diamonds.

however, despite the good performance, their bikes look like they have been beaten with the ugly stick, and I would be worried about ripping my nuts off on the moving upper swingarm, if I sat down too hard Wink

 STINKY-MINTY-1,

C'mon man, there are plenty of times when bike cops are needed. I know I've been to many large events in the city where bike police have been roaming about. They can cover more ground, that's for sure. Having spent a long time in a shop that looked after the local bike force, I also do happen to know that they do take people down on the bike while moving, more often than one might think =) Sure would like to see that go down!

 Bikes are definitely far more nimble in the city than cars - and perhaps the cops I once outran on my BMX woulda had a chance if they were on bikes... ... but I doubt it! And anyone who commutes through a busy city knows its always faster by bike - even obeying the stop lights. Otherwise bike messengers wouldn't be so popular.

 I've been riding this exact same frame all season long and it is very nice to ride!! Very good small bumps compliance, great acceleration under pedaling and it takes tight corners like a charm. It is the best DH bike I've own for my riding style!
The weight of the frame/Elka shock/headset/maxle comes at 11 pounds. My whole bike comes at 42 pounds pedals included with not so light Shimano Saint components, Avid Code brakeset and Fox 40 RC2 fork. As for the nutsack crushing thing...never happened to any of the 7 guys I know who own this bike.

 It's impossible to have anything without a Center of Gravity.

If you meant "high" center of gravity (rather than "no"), I am very impressed that with just a few photographs of a bike you can calculate the center of gravity well enough to comment on it.

 I meant its got a high COG, And thank you, i pride myself in the ability to calculate the center of gravity through a photo.
  • 5 0
 In the grand scheme of bicycle physics, calculating the center of gravity of a bare frame is right between a worthless exercise and marketing hype. You have to count on a complete bike, and most importantly a rider. As we tend to move on bikes while riding them, the center of gravity becomes quite dynamic.

On the other hand, if you had looked at the relative height of the BB as compared to the hubs, and determined that the BB looks high (again, on an unloaded, unsagged bike, so it might be a worthless estimate) then I might have agreed in the first place.

 No comment your too nerdy. Im comparing every bike that comes out with the new demo, because of its very low COG. Which i like as a rider, because you have more control in corners and jumps IMO...

 I think low COG is overrated anyhow. Low COG feels heavy in the air to me, and I end up doing a lot of straight airs. I miss my old Iron horse sgs. SO much fun.

 you compare all bikes to a demo 8, even though you ride a trek, have you ever ridden one? in rocks you have to choose very carefully where and when you pedal, and it is true about the straight airs. but the main prob is pedals hitting the deck when you're running 165mm cranks. are you on the sam hill trip?
