The Santa Cruz Tallboy CC Mountain Bike Frame is a truly worthy platform for the versatile trail bike you've been dreaming of. Capable of being set up with 29 inch and 27. 5+ wheelsets, and primed to tackle your biggest ride, this highly refined machine has a serious demeanor that's tempered by a mile-wide fun streak. Many of you will remember the commotion that the original Tallboy caused, what with its lively handling that immediately dispelled a mountain of preconceived notions about how 29-inch wheels were supposed to handle. The latest iteration of the Tallboy retains its praiseworthy handling with an added dash of versatility and a pinch of aggressive intent that takes the Tallboy into uncharted territory. Part of the story of the Tallboy's success is due to its ability to blur the lines between cross-country rocket and surefooted trail bike. To that end, the Tallboy was built to accommodate 27. 5+ wheels as well as 29-inch wheels. This split personality is enabled by the reversible "flip chip" at the upper link. Setting the flip chip to the "low" mode relaxes the head angle by roughly half a degree and lowers the bottom bracket, which makes for an ideal setup when paired with the slightly larger diameter of 29-inch wheels. The slightly smaller 27. 5+ wheels pair with the "high" setting, allowing for similar clearance between the bottom bracket and the ground. The upshot is headache-free swaps between wheel sizes, which gives you more options than ever when you hit the trail. The Tallboy generates 4. 3in of travel through the latest version of Santa Cruz's VPP technology. As with all VPP bikes, the Tallboy's counter-rotating links are carefully arranged to resist activation by pedaling forces, all but eliminating unwanted bobbing under power. This being the latest iteration of VPP, it's tuned to provide more midstroke support than previous generations of the VPP platform, giving the rider a better feel for the terrain and a livelier ride feel.
