Spearfish C Eagle 90 Mountain Bike

What Our Gearhead® Experts Are Saying:

"I like this build for riders who want cutting-edge drivetrain performance without stepping into a full race-only setup. Transmission shifts perfectly even when you’re tired and pushing hard, and the suspension stays supportive without wasting energy. It’s a dialed endurance bike that rewards steady power and long rides."

The Spearfish C Eagle 90 Transmission Bike is designed for endurance riders who demand consistency, efficiency, and control across long distances. Salsa built this platform to thrive in the toughest single- and multi-day XC events, where energy conservation matters just as much as outright speed. The lightweight carbon frame and endurance-focused geometry create a composed ride that stays comfortable and efficient deep into long efforts.

Salsa’s Split Pivot suspension system delivers 120mm of rear travel that remains active under braking and supportive through the mid-stroke, keeping traction high on technical climbs and rough descents. The Split Pivot+ design allows rear travel adjustment from 100 to 120mm and supports forks from 100 to 130mm, while a rear flip chip fine-tunes head tube angle and bottom bracket height for terrain-specific performance. Clearance for 29 x 2.4-inch tires adds comfort and grip without compromising efficiency.

The SRAM Eagle 90 Transmission drivetrain brings next-generation shifting performance, maintaining crisp, reliable gear changes even under load. Paired with durable trail-ready wheels, powerful disc brakes, and a dropper post sized for each frame, the Spearfish is built to handle long training rides, endurance races, and backcountry XC adventures with equal confidence.
