Sea Otter - Tomac Carbide SL

Over three years in development, the Carbide SL is the ultimate in lightweight, stiffness and pedaling efficiency. At a scant 4.4 pound frame weight with DT Swiss carbon shock, it’s one of the lightest XC full suspension bikes on the market, and certainly the stiffest. The Carbide SL can be hammered through anything an XC rider or racer could throw at it.

21.13 pounds

21.13 pounds

Features
•90mm rear travel
•4.4 pound/2000 gram frame weight with DT Swiss shock, large size
•Optimized carbon fiber front triangle, individual lay ups for each size
•High modulus carbon fiber with aluminum dropouts
•Shaped aluminum chain suck protector.
•Low stand over height with plenty of seat post adjustability
•Only three sets of bearings means easy service
•Accepts dual water bottles on all but the small frame
•Available in small, medium, large and extra large

The Background
Let’s face it, the buzz on carbon has every bike company out there diving into weaves and resins at an alarming rate. The result is a plethora of poorly though out, designed and executed carbon full suspension bikes. Some may be light, but lack the stiffness. Some may be stiff, but lack the lightness. It seems no one got the formula right…until now. Introducing the Carbide SL, the ultimate in lightweight and stiffness.

It’s no real mystery why weight is a critical element of a bicycle, but stiffness is often a far secondary consideration. It’s really unfortunate, because it translates into greater rider control, improved durability (a stiff package means the bearings aren’t being side loaded) and better suspension action. Being stiff also gives the Carbide SL versatility. Bikes that are overly flexy may be good enough for a two hour XC race, but can’t really handle a rough XC ride. Our goal with the SL was to make a bike that was stout enough for real punishment.

But stiffness and lightweight don’t just come easy. It took three years to develop the SL, and in the end, it’s a masterpiece of hand construction. Additional layers of carbon on the bottom of the down tube and top tube work to distribute loads evenly, stiffening layers on tube sides (when they have the greatest effect in bending) reduction lateral flex, box section top, down and seat tubes to counter lateral bending and rounded tube-sides counteract torsional loading and specific lay-ups for each size. These are just a few of the reasons for the winning combination.

And that’s just the front triangle…the rear triangle is the area that typically sees the majority of flex. The Carbide SL features an all new carbon swingarm. By design alone, the fully triangulated swingarm, attached to the front triangle with a compact hollow-forged link, provides a high level of stiffness. But with focused use of high modulus carbon fiber, we were able to maximize the stiffness without adding any extra weight.

Sold as a frameset at $2599USD and a complete bike model, the Carbide SL 1, at $5499USD.

 But is it really that impressive? Correct me if I'm wrong but isn't the Ibis Mojo (with WTF kit) 21.9 lbs for a 5.5 inch front and back suspension?

 Don't be fooled that IS a light frame and is more than on par with the lightest FS frames out there. The build isn't anything especially light though and there's lots of room to drop the weight without losing any ride quality. Perhaps sponser commitments result in the "average" weight...

 Oh yah, I realise it's silly light. I was just being a bit facetious in my support of the AWESOMENESS that is the mojo. Also, having never ridden a mojo I cannot say how it performs in terms of stiffness, which I can easily imagine this, being a cross country beast, excelling at.

But heh, my scott addict used to be 14.4 lbs, lol (not to be used for real riding).

 Price is great too, A good custom build can easily run 7 or 8k, same with the high end trek and specialized bikes, at between 1500-3000 dollars off this bike is a steal.

---this person obviously didn't see that the Scott's are $12,000, twice the price of this Tomac.....hard to compare a bike that costs double...

 Carbon is the way forwards- feel so much nicer to ride a bike with a bit of terrain compliance! Not sure that every manufacturer got the whole idea of the composite frame wrong though as some were meant to flex, some weren't meant to be light- however it's nice to see development going on. It's also nice to see the carbon version of my shock being used in a retail bike!

 That looks light as hell!! Would be a sick racing bike, however i'd still take the Specialized Epic over it.. and maybe slap that DT swiss fork on the front. Wink

 Ahhh, you spied the new Camel-Bak hydration system. With every bump the fork hits, a tiny sip of water is pumped directly to your mouth via the straw through the top of the fork leg. LOL
