Since its last round of revisions, Santa Cruz's Tallboy Carbon CC Mountain Bike Frame has displayed aggressive climbing, surprisingly nimble agility on descents, and four inches of Virtual Pivot Point VPP travel that eat drops and flowy singletrack without sacrificing the kind of always planted tiretrail contact that made the original Tallboy the touchstone of 29ers. It's not only light and stiff, but the retuned shock rate is even more resistant to bottom outs, so the latest Tallboy takes drops and steps more like a trail bike. Given these properties, we're happy that it's returning for 2016 with no other changes besides aesthetics, sitting pretty on a winning platform. When the Tallboy was most recently under the knife, Santa Cruz was smart enough to let a good thing well enough alone. Instead of fiddling with its best seller's geometry, Santa Cruz instead looked at ways to shave weight and improve stiffness. The resulting frame is significantly lighter than comparable designs on the market. These gains are owed primarily to Santa Cruz's inimitable Carbon CC frame construction, which features a higher modulus carbon than the Carbon C model, so less material is required to hit the same strength and stiffness numbers. The chassis is lighter, so fewer watts are required to propel it, and the increased stiffness means those watts are transferred more efficiently. The frame's two carbon triangles are built as whole pieces rather than glued together from disparate bits. This saves weight and increases structural integrity by allowing Santa Cruz to wrap carbon continuously through and around key junctures, eliminating the artificial stress points that result from bonded construction methods while saving weight by requiring less material. Finally, the carbon is also compacted from the inside and the outside for a more even finish that avoids any structural defects, excess material build up, and resin pooling for you guessed it even more weight savings.
