2025 Santa Cruz Hightower 4 CC X0 AXS RSV

The 2025 Santa Cruz Hightower 4 CC X0 AXS RSV is built to handle everything the trail throws at you. Technical climbs, fast descents, and rough terrain are all dealt with confidently thanks to thoughtful design and high-end parts. You’ll notice the smoothness from the FOX suspension right away, while the wireless SRAM drivetrain makes shifting effortless, keeping your focus where it belongs: on the trail.

Suspension Details

Up front, the Fox 36 Float Factory fork with Grip X2 damper and 160mm travel cushions sharp impacts and keeps you steady on tricky lines. At the rear, the FOX Float X Factory shock lets you dial in exactly how the bike responds. It's smooth through the chatter and ready to bottom out only when you ask. That suspension combo gives you more control and confidence day after day.

Drivetrain Features

The drivetrain is pure tech. Wireless SRAM X0 Eagle AXS controls twelve gears spanning a huge 10-52 tooth range. Whether you’re crawling uphill or sprinting downhill, shifting feels crisp and immediate. The onboard AXS Pod Controller with rocker paddle sits naturally under your thumb for quick gear changes without interrupting your flow. Paired with a stiff 32t X0 Eagle crankset and a wide DUB bottom bracket, pedaling efficiency and power transfer stay high no matter how aggressive you get.

Wheels and Tires

Rounding out the ride are Reserve 30|HD carbon wheels that balance light weight with strength and durability. Industry Nine 1/1 hubs offer fast engagement and smooth spin, so you can accelerate out of corners and stay locked in. Maxxis tires on both ends provide traction tailored to their role: the DHF up front grips corners like a champ, while the DHR II in the back excels in braking control. Both tires carry robust casings to resist punctures and abuse from rough trails.

Brakes and Cockpit

Stopping power from SRAM Maven Silver brakes is strong and reliable, giving you confidence when the trail takes a sharp turn or sudden drop. The cockpit features a Santa Cruz 35 carbon handlebar that’s wide enough for control, paired with either OneUp or Burgtec stems, both engineered for rigidity and solid handling feedback.

Seat and Dropper Post

A OneUp dropper post with adjustable travel means quick saddle height changes for climbing and descending without missing a beat. Complementing the setup, the WTB Silverado Medium saddle balances comfort with support, making it easier to spend all day in the saddle without discomfort.

This is a bike that shows up ready to rock and roll. The 2025 Hightower 4 CC X0 AXS RSV pulls together premium parts and smart design in one package built for riders who want a dependable, all-around trail machine free from compromises.
