Highball C Eagle 90 Mountain Bike

What Our Gearhead® Experts Are Saying:

"If you want every pedal stroke to count, the Highball 90 is your bike. It's light, fast, and clean thanks to the T-Type wireless drivetrain. The carbon post and SID fork help keep things smooth when the trail gets rowdy for a hardtail. This build is dialed for the modern XC rider."

The Santa Cruz Highball 90 is the modern XC racer's dream: a carbon hardtail engineered for pure speed and ruthless efficiency, without sacrificing the comfort or control needed for long, grueling rides. At the heart of the build is the Carbon C frame, designed to deliver precise handling, minimal weight, and subtle vertical compliance—all in a platform that’s race-proven and trail-trusted. Its progressive geometry keeps things confident on high-speed descents while remaining responsive and agile on technical climbs.

Paired with a 100mm RockShox SID SL Select+ fork and a handlebar-mounted remote lockout, the front end remains firm on climbs and active on descents. The SRAM 90 Eagle T-Type drivetrain brings a next-gen wireless shifting experience with a wide 10–52t range and unbeatable chain retention. A SRAM DB8 brake set keeps stopping power consistent and smooth with minimal fuss.

Wheel duties are handled by RaceFace AR Offset 27 rims laced to DT Swiss 370 hubs, providing dependable performance and quick engagement. Maxxis Rekon Race tires offer minimal rolling resistance while still delivering reliable grip. With three bottle mounts, a comfort-oriented 27.2mm RaceFace carbon post, and a well-balanced cockpit, the Highball 90 is the total XC package—perfect for dedicated racers or riders looking to push personal limits on every climb and descent.

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.
