Big wheels, big brakes, more travel, and even more tech: the Santa Cruz Bicycles Hightower CC XX1 AXS Reserve Complete Mountain Bike instantly takes a top spot on trail riders' dream lists. One look at it and you’ll get the idea. This redesigned model sees the shock moved to the downtube, the addition of a droolworthy 150mm Lyrik Ultimate up front, a 65° head angle, and SRAM's AXS Eagle wireless group--the pinnacle of modern drivetrains. Tell your local trails to get ready to see some new KOM’s, because this bike is rearing to go! With a lifetime warranty on the frame and wheelset, this carbon-crazy build has riders obsessing.
Carbon CC Frame – Santa Cruz's highest grade CC-level carbon frame is every bit as stiff and strong as their C-level frame, but weighs about 280 grams less, due to the use of lighter, stronger, and more expensive carbon fiber. Santa Cruz is also able to truly integrate the shock mounts, pivot mounts, dropouts and disc brake tabs into the structure, using all uni-directional carbon plies. The shock mount isn't merely riveted or bonded on after curing, but is an integrated part of the fiber lay-up. This makes Santa Cruz's carbon frames incredibly strong and able to absorb impact better than any other frame they've tested.
140mm VPP® Suspension – VPP is based on the patented principle of having two short links rotating in opposite directions. This system provides huge design flexibility, allowing Santa Cruz to manipulate shock rates to the intended purpose and character of each model; from short travel endurance bikes to World Championship winning DH machines. This redesign mounts the shock lower on the bike, making for an even better ride quality.
RockShox Super Deluxe Ultimate Shock – Designed for the latest hard-hitting enduro and trail bikes, Super Deluxe Ultimate features the ride-tuning abilities of an air spring with both compression and rebound adjustment to fine tune to any trail. With a solid threshold adjustment for pedaling performance and Maxima Plush fluid for a buttery smooth feel, riders can now easily dial in a podium-worthy ride.
Shock Adjustments – + / - Low Speed Compression Adjustment from Base Tune, Open / Threshold Positions, External Rebound, Air Spring Pressure
Bottle Cage Mount – Within the front triangle, fits piggyback shocks.
Integrated Flip Chip for High/Low Setting Adjustment
Molded Rubber Swingarm and Downtube Protection

RockShox Lyrik Ultimate – Designed not only for the race down, but the ride up. Holding onto every critical line, Lyrik Ultimate features the new Charger™ 2.1 damper for unmatched trail control and precision. New ultra-low friction SKF wiper seals and Maxima Plush damping fluid all work overtime to reduce friction, silence noise, and provide unmatched fork performance sun up to sun down.
Fork Adjustments – New Charger 2.1 RC2 Damper with External Rebound, Independent High and Low Speed Compression and Air Spring Pressure Adjust
SRAM XX1 Eagle™ AXS Wireless – XC spec and ready for the trail. XX1 Eagle AXS™ utilizes the proven backbone of SRAM 1x™ and combines it with an integrated system that connects electronics and software. Made with the lightest weight materials and a 500-percent gear range, this group features the more secure and longer wearing X-SYNC™2 chainring. This is the pinnacle of performance, paired with the connected components of Eagle AXS™. Ready for the new gen of superbikes.
SRAM Code RSC Brakeset – Code RSC is built from the elements that made Guide a benchmark in contemporary brake design and performance, and delivers an extra 15% power to shine in all heavy duty applications. SwingLink™ and Lever Pivot Bearings ensure a smooth and progressive feel at the lever, while the additional 30% positive fluid volume ensures consistent performance even when braking harder, more frequently or with a heavier mass to slow down.
Avid CenterLine Rotors – The new CenterLine Rotor was designed to keep the center of friction consistent throughout rotation thereby minimizing vibration offering consistent performance and a quiet ride.
Santa Cruz Reserve 30 29" Carbon Wheelset – With i9 hubs laced to 30mm wide carbon rims, these wheels are built to last as the best on the trail with a lifetime guarantee. Lightweight, responsive, and bombproof, they're raceworthy hoops for everyday--and lifetime--riders.
Maxxis Minion DHR II Tires – The trail version of the Maxxis Minion DHR II features the same tread pattern as its downhill counterpart, but uses a single-ply casing to reduce weight. With side knobs borrowed from the legendary Minion DHF, but widened to provide more support, the DHR II corners like no other. The center tread features ramped knobs to improve acceleration and sipes to create a smooth transition when leaning the bike. Paddle-like knobs on the center tread dig in under hard braking and help keep the bike under control.
RockShox Reverb Stealth Dropper Seatpost – Don’t let its familiar good looks fool you—Reverb is a whole new weapon. Its internals have been completely re-engineered to improve on its already legendary performance and to offer enhanced reliability: all the smallest details, down to the single seal, have been re-evaluated and updated to pass the hardest and longest durability tests. Additional bushing overlap also improves performance over time. This is the brand-new Reverb, engineered for the next-generation mountain biker.
