In the field of low travel bikes that straddle the divide between XC and trail, few models enjoy the flexibility afforded by the low, stable bottom bracket and steep, agile head tube of Santa Cruz's Tallboy Carbon S Complete Mountain Bike. Add to this the small bump compliance and mid stroke support of Virtual Pivot Point suspension and the one by SRAM drivetrain at the heart of Santa Cruz's S build kit, and the bike straddles the divide between race days, training rides, and IPA fueled weekend sessions just as easily. With the exception of a few alterations made with an eye toward saving weight, improving frame stiffness, and producing a more linear feel to the Virtual Pivot Point VPP suspension, Santa Cruz has left the Tallboy largely untouched since it first demolished the myth that 29ers can't be nimble at its launch in 2009. The changes to the frame are symptoms of Santa Cruz's obsessive tinkering with carbon technology, culminating to date with the Carbon CC and Carbon C flavors, the latter of which features here. Compared to Carbon CC, Carbon C incorporates a lower modulus carbon, so it requires more material to hit the same stiffness that Santa Cruz requires from all of its bikes. More material means more weight, to the tune of about 280g, claimed. Still, that's a small sacrifice to make when pennies are counted against grams, and the overall efficiency of the frame remains the same as the much more expensive Carbon CC model. 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...
