So now we all have creaky tapered steerers and frames that aren't long enough, isn't it time we went back to the short travel dual crown idea from a few years ago?

To me it makes a lot of sense if the weight and stiffness of the current 36 could be met or improved.
1.1/8th" steerer would allow for reach adjust headset cups with a 44/56 headtube.
Takes stress away from the lower steerer interface.
Direct mount stems?
20mm axle...

So, Chris Porter has a hideous bike with a stripped-out 40 set at 180mm. He says it weighs the same as a 2013/14 34 TALAS....

No

Nice 40lb enduro bike

 

[jstuhlman]

b-b-but...didn't you read? He's maximized the suspension performance and moved the weight to low and center so it's stable. Plus 62* head angle! So much winduro!

 

[kickstand]

maybe I'm just not enduro-bro-rad-stoked enough, but my bike is not flexy enough to warrant a dual crown fork for trail riding.

 

[Metamorphic]

On a DH frame, yes, but directly applicable to trail steeds, and I like where he was going with it.

 

[4130biker]

Freeride is back!

 

[ianjenn]

62 DEGREE HA

 

[Toshi]

That bike seriously does look unrideable.

53" wheelbase.


Because riding bikes is hard and it's up to the bike to just do everything while the human is a passenger. That's really the whole theory behind all this shit. That bike would literally not fit around a lot of turns.


As far as the dc trailbike forks......hell yeah. The chassis on those old specialized enduro forks was rad. Everything else sucked but if you really could get the sub 5lb weight, I'd totally be down. That's still probably the stiffest trailbike fork I've ever ridden.

Maverick no so much.

 

[kidwoo]

As far as chris porter goes

It goes without saying that Chris knows an incredible amount about suspension performance and set-up, but he’s also fastidious about general bike set-up, geometry, body positioning, tyres, and anything else on a bike concerned with going faster and getting the most from the terrain.

 

[Udi]

He must ride trails that are designed according to this:

Good to see people paying attention as usual, CP's bike is too out there for most but the point is he's made a Fox 40 that weighs less than 5lb!

That Specialized fork is the closest example of what I'm thinking of. A DC fox 34/36 with either rc2 or fit4 damper that came in around 4lb would be amazing.

I'm on a 2016 34 fit4 now and while the damper is fantastic I can't help but wince at the noises from the steerer when hammering on the front brake and the feeling of the front wheel flexing rearwards. That's from the crown, it's the highest point of leverage.

 

[kidwoo]

I doubt it.

 

[goodgrief]

It's on the internet, must be true.

 

[trib]

the maverick double crown was ahead of it's time. It was also admittedly a little bit shit, but still - ahead of its time.

that's your fault for buying a 34

 

[goodgrief]

Same crown/steerer as the 36, same weak point as all the other 160mm forks that develop creaks due to flex.

Adjustable reach would be a bonus too with a 56mm or 1.5" headtube and 1"1/8th steerer. People are different sizes, finding the right bike is a nightmare. Turner is getting there with their 65mm headtube but IDK how much adjustment that will give you with a tapered steerer.

 

[maxyedor]

what all did he remove to get a 40 that light?

Was not aware that manufacturers shipped forks with that many useless parts in them.

This is not a Fox 40, but custom built fork. It probably has some cut down stanchions, 180mm damper from 36, air spring from some smaller fork, and so on.

 

[jstuhlman]

dumm. i've never heard of a single person complaining that a 36 is flexy.

the article states it,s a modded Fox 40

• Fox 40 fork, set at 180mm – Chris prefers the stiffer feel over the 36. This particular set of forks have been custom built from the inside out, and weigh about the same as 2013/2014 Fox 34 TALAS forks!

Ok, so a fork that's as stiff as the current 36 but better in the ways that have been mentioned.

unless I missed something, the only thing mentioned as 'better' was that is allegedly stiffer, and allegedly doesn't creak

How is that different from what I've said? It is kinda obvious that only the chassis is from the 40, the damper and spring system have to be from a different fork or custom made for this one. This fork weights ~1lb less than the stock 40...

 

[jstuhlman]

so if no one complain about stiffness of normal 36s and most people don't have ones that creak...a gigantic waste of time and money for no appreciable gains on a bike with stupid geometry that's ridiculously heavy...OOOOOOHHHH...SIGN ME THE FUCK UP FOR THE STUPID PREMIUM PRICE.

Just fork over your money.

Dude that guys saddle is almost as fucked as mine

I am guessing that the 36 was never intended to be mounted on a bike with a 62 HA and a 53" WB that could be casing 50' jumps on a somewhat normal basis. I would imagine the load on a steer tube that raked would be pretty significant.

Maybe worse, at least yours is level(ish) IIRC.

that's not an am/enduro bike then. ride a proper fucking dh bike. and that gui isn't doing that stuff either. casing 50' gaps... keep on believing, bro...

 

[Udi]

Considering the same guy built a damper that adjusts both compression and rebound in one adjuster, and also seems to think a bike that weighs 40lbs and is 1km long is an enduro bike, it's safe to say that the fork is pretty well guaranteed to be a giant POS, especially if it really is as light as he claims.

The new Fox chassis for the 36 and 40 are heavily weight-optimised. Reducing their weight substantially from this point would involve sacrifices that aren't reasonable.

 

[ianjenn]

Hey I am being an optimist with a 50' if this 9 year old can jump 170' why not 50' for a 25 year old...

 

[no skid marks]

I agree with the OP. Triple clamps have Possible advantages over singles, less height for same travel, more travel for same height(lower A-C height)stiffer for less weight, 1 1/8th steerer, more bush over lap if desired, more space for internals.
Just dud for x ups that I don't/can't do anyways. Can be designed to not inhibit steering. More durable/less crown creaking. Anglesey friendlier.

 

[MikeD]

I want my Manitou Sherman Slider back!

 

[dan-o]

Same crown/steerer as the 36.

Fox uses the same crown for both 34mm and 36mm?
Must be using WTB Padlock technology or at least moar shimz for that to work.

 

[Sandwich]

i used to really want a dual crown fork for xc but man, the new forks are really good, and not heavy.

 

[kidwoo]

The only singlecrown fork I've been completely happy with stiffness-wise was a tapered steerer totem. So yeah, I agree, it would be rad to have a super pinner dc trailbike fork.

I'd almost get the crowns and stanchions from one of those e150s and start there. You could probably get a charger damper in one.

Didn't those have that stupid long integrated stem though?

36 lowers + Dorado stanchions + witchcraft = win?

Edit: JFC I'm not with it this morning. Totally forgot that the Dorado stanchions/dropouts are one piece.

 

[Toshi]

I guess I was totally ahead of my time when I rocked my 150 mm Marzocchi Super T back in the day. Turning radius sure did suck ass, though.
