Santa Cruz Hightower 4 C 90 — Built to Send, Built to Last

The all-new Hightower 4 C 90 is the big mountain bruiser you’ve been waiting for. It’s packing the brand-new SRAM Eagle Transmission (Eagle 90) for flawless wireless shifting under pressure, and the freshly released SRAM Maven brakes that’ll make you believe in stopping again.

Out back, you’ve got Reserve carbon wheels with a lifetime warranty, ready to take a beating and keep spinning true. Up front? A OneUp carbon bar and dropper post, for dialed cockpit feel and that smooth, Canadian-made dropper action we love.

This is the most refined version of the Hightower yet. 150mm up front, 145mm out back, and geometry that’s stable enough to charge but still fun to throw around.

Climb it. Rally it. Repeat.
