BTW, I think the Chinese need something to copy before they can come out with their own frame. God knows I need a Chinese knockoff carbon bike frame so bad. I don't know how people have managed to ride steel/titanium/alloy that was not copied and made cheaper illegally.
From Bruce Martin of 38 Frameworks:
"The head tube and seat tube angles are 70.5 and 73 degrees. Effective top tube for a medium frame is 23.75 inches and 24.5 inches for a large frame. There is no specific fork the frame is designed for but we have been using the Carver carbon fork on our test bikes. Weight for the medium frame is approximately 3.5 lbs. The rear triangle is asymmetrical and designed for a 170 mm rear hub. This provides clearance for 4.7 inch tires on an offset rear wheel (10.5 mm to the drive side)...4 week lead time for new frame orders and pricing is $2,400 for frame only and $2,600 for a frame / Carver carbon fork package (based on availability of the fork)."
Yes, looking forward to that as well. I'm sure 616 and Quiring will have their fat bikes as well. But just like regular MTB's, you save maybe 3 pounds off of a frame by going carbon. The real weight loss/performance potential will be in carbon rims and lighter tires.
Personally this is really exciting. FatCarbon can give shapes that are doable but heavier w aluminium. i want my next fatbike (aka this spring....) to be carbon w front suspension and sub 29lbs.
Am I the only one who LIKES the fact that their fat bike is like a rolling pig? I've got my super light, super fast carbon HT (19lb custom Scott Scale), it's got it's place in the quiver. When winter comes and the trails are covered in snow going fast is the last thing on my mind. After a long year of XC, road and cross racing fat biking is my time to kick back, forget about lactic acid and have fun with my buds.
I like the heavy wheels too (holy rolling darryls, heavy surly tubes, 120tpi Lardomorph). I find when I get off the packed line into the deep snow the gobs of rotational inertia help me keep plowing through until I can make my way back to the packed snow.
Sometimes it's taking me, other times I'm taking it - methods ranging from carrying it a thousand feet up a scree slope, dragging it through dense heather, lifting it over 7' deer fences, to throwing it across deep creeks.
If I was just pedalling the bike, I wouldn't care, but for the way I use my bike, light is good.
First carbon, then, Trek will discover them and "perfect" them by making it hopelessly proprietary, and convincing the uneducated masses that they are in fact, the pioneering brand.
I think most of you are blowing this concept out of proportion.
With all the weight weenie-ing that has gone on to get mountain bikes to their conventionally sold state that they're in now... you do realize that people still buy a lot of Surly brand bikes *because* of their durable reputation and not exactly svelte weight?
I don't think it's going to change anything. Not going to reduce weight all that much. Just an additional option for people that nerd out on carbon. Self included.
Here's one thing that hasn't been brought up about carbon, and surprises me. Special down tube. Make room for a significantly larger frame bag while completely ditching any suspension fork compatibility. I think it's a reasonable idea.
Carbon fiber fat bike tech certainly will not appeal to everyone, but for the folks who are taking fatbikes into the AM/XC race realm (I am thinking of bikes like the Sandman Hoggar) it makes as much sense as titanium. How bad ass would a sub 25lb carbonium trail fatbike on 47mm rims be? I'd ride a bike like that in a second. I'd still keep my Pugs, though.
Carbon frames are typically only about pound or so less then hydroformed aluminum "race" frames. So take that off a Beargrease frame and there is a reasonable expectation of weight. But in no way is it going to make a very dramatic difference in the weight of these bikes. It's the combination of parts you use that really cut the fat
Well, I like going fast! I have been riding my 9-0-7 Lefty, BFL's on Clownshoes, 32-33#'s, on all the trails I can find and I am riding with my bud's on their 26 and 29 er's. They can't believe the fatty is not a slow pig. I let everyone ride it to see for themselfes. This bike rocks the technical trails instilling confidence because of the extra traction. Also the super tire diameter helps it roll over logs and rocks better than my 29er.
I will take a carbon frame and anything else carbon if it saves weight and is strong enough to withstand my riding style.
Did not think CF frames were still made in the USA? I am waiting on the "Fat Chinese Carbon" thread to appear, even before Trek/Giant/Specialized get into the market. CF frames are not my cup of tea because I crash too much.
A little weak internet sleuthing has me guessing it will be Funk Cycles from CO, that shows up at the 2012 Bells Niceman Expo with a "Carbon Fatbike frame". They should have plenty of metal based Fatbike company at the Expo. http://www.funkcycles.com/about.php
tazducks, are you lining up fat in Kalkaska on Nov 3rd? Fat Triple Crown in play?
Would be cool to have a "HEAVY" (metal) and "light" weight (carbon) wheel set. Get your training in during the week then go play on the weekend. Carbon frame would be cool as well. Waiting for the clunker carbon fat bike to hit the market.
Think it would be cool crossing the lines of this bike
The scrappers wont come and grab my non recyclable frame from the dumpster when it becomes obsolete. I will probably just have to burn it, along with the tires and some 'black water' from my car's last fluid change.
Does carbon have a hand signal like \m/etal does?
I have an original purple Pugsley and love my tank! I think it is great that new products are coming out and that people have money to burn on carbon forks, super light rims and such. It is great to ride these bikes year round but in the end they are meant for winter riding where you end up wearing tons for clothes and can only fly down the trail so fast!
Weight wiennies may have their place but I don't think the area of the Fat Bike is it.
^ Yeah the first time I took mine out was summer and I road shirtless. Among the places I road to was a beach, where whipped around beach goers to show off my new awesomeness. Then I kicked sand in the face of a guy and road off into the sunset.
Why'd they have to go and use an asymmetrical 170mm rear triangle? What's the offset?
