Mountain bikers are often caricatured as beer swilling, lowbrow versions of their skinny tire counterparts, uninterested in anything but the thrill of mud covered, terrain smashing lunacy. We contend that this is unfair, as many of us appreciate the multifaceted refinement of a bike like Ellsworth's Evolve Carbon Mountain Bike Frameset. The Evolve is not only handles terrain with confidence, but it also climbs well and has the cross country speed pedigree of 29 inch wheels. It doesn't skimp on good looks, either, with Ellsworth claiming that it's a piece of performance art. We agree, and we've found that the best way to appreciate this particular piece is covered in mud while enjoying a cold beer after a maniacal run through a rock garden. The Evolve Carbon is built with Ellsworth's Force Vector Anisotropic Design, which translates into unidirectional Toray carbon fiber laid up in varying shapes and wall thicknesses in order to strike a balance between weight and energy transfer while keeping the suspension system's pivot points aligned. In the rear triangle, the addition of CNC machined aluminum rockers and chainstays makes for an even stiffer drivetrain, and the single 12 millimeter bolt needed for each pivot assemble makes for a lighter, less complicated system. Fewer parts mean fewer issues, and you can ride confidently knowing that the part that is there happens to be the size of your rear axle. The semi integrated tapered head tube takes advantage of the steep head tube angle for a stiff front end that elevates 29er steering to levels you'd expect from smaller wheels. Ellsworth claims that the Evolve Carbon's Instant Center Tracking ICT suspension is the most advanced suspension platform in the world. As it moves through travel, ICT keeps the instant center or virtual pivot created by ICT's four bar suspension as close to the chain force line as possible. In on trail terms, this maintains a steady pedaling platform so your power is always transfer...
