Highball C Eagle 90 Mountain Bike

What Our Gearhead® Experts Are Saying:

"I’ve ridden a lot of hardtails, and the Highball 90 stands out for how fast it climbs and how stable it feels at speed. The carbon frame feels razor-sharp on punchy terrain, and the T-Type drivetrain shifts buttery smooth even under load. It’s my go-to for long XC races and fast trail laps when I want pure speed."

Whether we're lining up for race day or chasing KOMs on our favorite lunch loop, the Santa Cruz Highball 90 gives us the relentless speed and razor-sharp handling we need to push our limits. This is Santa Cruz’s purebred XC hardtail—light, responsive, and built around their Carbon C layup that balances weight and durability for riders who demand speed without compromise.

The Highball 90 build features SRAM’s cutting-edge T-Type transmission, delivering crisp and dependable shifting through a 10–52t cassette that eats steep climbs for breakfast. Up front, a RockShox SID SL Select+ fork with remote lockout keeps the ride efficient on fire roads and composed through chattery descents. And with modern touches like 3 bottle mounts, a 27.2mm carbon post for extra comfort, and DT Swiss 370 hubs laced to RaceFace AR rims, we get a race-worthy ride that’s just as good for epic weekend loops as it is for the podium.

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.
