Santa Cruz Tallboy 6 CC 29 XT Di2-Kit

If you ride Shimano and you ride hard, this is the Tallboy for you. The XT Di2 build pairs Santa Cruz's most versatile Carbon CC 29er with Shimano's new wireless XT Di2 drivetrain, giving Shimano loyalists a top-shelf trail bike without compromise. 130mm of rear travel through a 4-bar suspension system and a 140mm RockShox Pike Ultimate fork up front. At 29.7 lbs, it's light enough to pedal all day and capable enough to handle real trail terrain. Excellent suspension, big wheels, and a thoroughly-tuned carbon layup let you ride as hard as you want, whether that's maximizing power hours or just trying to ride every hour you've got.

The Shimano XT M8250 Di2 drivetrain is the headline here. Wireless shifting with the precise, snappy engagement Shimano has built its reputation on, paired with a 10-51t XT cassette and 32t crankset for any climb you can find. RockShox Pike Ultimate and Deluxe Ultimate suspension front and rear deliver premium damping with all the adjustability you want to dial in the ride. SRAM Motive Silver brakes with a 200mm front HS2 rotor put down serious stopping power. Reserve 30 SL AL rims on DT Swiss 350 hubs with MicroSpline freehub roll on Maxxis Forekaster 2.4 tires in MaxxTerra EXO casing, a fast-rolling combo with enough grip for mixed conditions. OneUp carbon bars, dropper post, and Santa Cruz CNC stem round out a cockpit that needs nothing on day one.

Beyond the spec sheet, the Tallboy frame is built to live with. The Glovebox downtube storage swallows tubes, tools, and snacks so you can leave the pack at home. UDH derailleur hanger, 73mm threaded BB, integrated chainguide, and one bottle mount inside the front triangle. Sizes XS through XXL with crank length, bar width, and dropper travel that scale to the frame so the bike fits the rider instead of the other way around.
