Hightower CC XTR Di2 Reserve Mountain Bike

What Our Gearhead® Experts Are Saying:

“This Hightower build hits that sweet spot: FOX 36/Float X Factory feel is supple off the top with real mid-stroke support, XTR Di2 shifts under load without drama, and the Reserve 30|HDs on Hydra hubs hold a razor-clean line. With 150/160mm travel and true 29er rollover, it’s calm when trails get blown out, yet snaps forward when you stomp on the pedals.”

We chase big, rowdy trail days, and the Santa Cruz Hightower XTR RSV is our go-anywhere answer. Santa Cruz’s Carbon CC chassis wrapped around VPP suspension gives the Hightower XTR RSV 150mm of rear travel that pedals crisply and stays composed when speeds rise. Paired with a FOX 36 Float Factory fork at 160mm and a Float X Factory shock, the bike floats through chatter, holds support in compressions, and stays eager to change lines the second we point somewhere new.

Shimano’s XTR Di2 12-speed drivetrain delivers instantaneous shifts across a 10–51t range, and XTR brakes with 203/180mm rotors keep power consistent on sustained downs. Reserve 30|HD carbon rims laced to Industry Nine Hydra hubs make quick work of square-edged hits, while Maxxis Minion DHF/DHR II tires in 2.5/2.4 balance bite and speed. Details seal the deal: a RockShox Reverb AXS dropper sized by frame, a Chris King DropSet 3 up front, ISCG-05 tabs, a threaded 73mm BB, and UDH compatibility—plus a real-world weight around 31.95lb that’s ready for alpine missions or after-work hot laps.

Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning—and sometimes the photos might not show the exact build you'll receive. If you want to double-check the details, our Gearheads are always here to help.
