Are there any shock forks available for fat bikes?

 

[shoo]

Yes.

maverick duc32, sc32. duc32 stiffer, more travel. both less than 4 pounds. i think they can only be found used, ebay, craigslist, here.

 

[Andy FitzGibbon]

Cannondale Lefty with Project 321 adjustable clamps.
Marzocchi Shiver SC (long discontinued, sometimes on eBay)
Some other double-crown downhill forks (that would mostly be too tall/too much travel for existing fat frames).
Maverick SC32 and DUC32 as mentioned. The DUC won't fit as wide rims as the SC will.

dont forget White Bros has the 150 dual crown as seen on the Sandman Fat tandem.

That is a Groove 200 reduced to 130 mm.

 

[bighit]

Even better, plan ahead for the first fat downhill bike.

You wouldn't want to put that Groove on a "single" bike, it weighs a ton... German-A and Sandman are working together on a suspension fork: an adapted version of the Flame USD model. It weighs the same as an SC32.
Compared to the series model it will have an adapted, wider crown for Surly tires on rims up to 80mm wide, 90mm travel, no travel reduction and tool-less removal of the wheel. They're still debating wether to use a proprietary axle or supply spacers for let's say a Hope 20mm through axle.
I've been testing one for some weeks now and it's incredibly stiff and works like it should, here's a view on a ride in Luxemburg we did last week.

None of those are true fat bikes. They are merely plump.

Not sure what you mean... define "true fat bike" ?

Edit : the bikes in the picture can take up to a 100mm rim in the rear, "truer" fatbikes you'll be hard pressed to find ;-). How fat you want to go with your personal ride is a question of intended use and taste: the above bikes are meant for fast & efficient travel over rough terrain, the 47mm rims, dropper seatpost, big brakes and the sus forks perfectly fit that role. I can easily do 6000ft+ days with it in the mountains and smile all the way up & down. I wouldn't be able to do that with 100mm rims.
If I'd decide to go live above the pole circle, I'd probably invest in a second set of wheels and maybe a stiff fork (and ditch my big ring during the winter months).

If I'd want a bit of both worlds, I'd put in rims between 65 and 80mm (and keep these sus forks). The heart of a "true" fatbike is the frame, and all current ones marketed as such can handle fat rims I think. The spec list depends on what you want to do with it and can be changed/swapped easily. That's like discussing colors, tastes, religion or politics ;-) !
Me, I'm getting rid of all my bikes (anyone interested in a nice Marin Mount Vision and a ti Rohloff bike, both in XL ?) and invest in two more wheelsets: a set of narrow rimmed 29" wheels for communting and those really muddy rides, and a set of 80mm rims for the soft stuff and bike park rides. One bike, which does literally all, you name it: light downhill, enduro, all-mountain, XC, chasing roadies, snow, sand... just by swapping the weels.

I'm guessing you mean "None of those are true fat forks", and I'm guessing you said that because they won't take 100 mm rims? MCS did have a Choppers US hundie on his Pugsley/Lefty for a while.

 

[Drew Diller]

caminoloco, any word on availability estimate? I plan to eventually build a FS fat frame after I get a few rigid frames under my belt.

 

[caminoloco]

I think they'll start production next week. So 6 weeks later...?

 

[Drew Diller]

Oh wow. Awesome.

 

[Dmonkey]

Great News!

Good to hear, looking forward to them!

ouch. that hurts man...

Respect :thumbsup: :thumbsup:, one of the most rad fatbikes I've seen !

Dare we ask the weight ??

Nice seat!
The WB fork is 7.5 lbs. by itself...

They're still debating wether to use a proprietary axle or supply spacers for let's say a Hope 20mm through axle.

When I first saw the spec for the fork/hub (105mm spacing, proprietary) I thought, why no 20mm TA, as it already has 110 spacing?
Fatbikes already have enough non-standard standards. If an existing standard works, use it!

 

[Velobike]

Fatbikes already have enough non-standard standards. If an existing standard works, use it!

I agree with that principle.

However I think wide spaced front forks need to have larger diameter axles to be as stiff as the current axles used on 100mm OLD forks. Ideally going for an existing alternative would be good, and it looks like hubs designed for the downhill bikes are where we'll find the larger axles.
