Salsa

Spearfish C Eagle 90 Mountain Bike

What Our Gearhead® Experts Are Saying:

"I’d put this build at the top of the list for riders who want a modern endurance XC bike with minimal compromises. The Transmission drivetrain is insanely precise under load, and paired with the Split Pivot suspension it feels efficient no matter how tired you get. It’s the bike I’d choose for long training blocks, stage races, or any ride where consistency really matters."

We trust the Spearfish C Eagle 90 Transmission Bike when the ride plan stretches from sunrise to well past when legs feel fresh. Built by Salsa for endurance XC racing and all-day trail mileage, this bike keeps efficiency high and fatigue low when the hours stack up. Whether we’re lining up for a marathon race or settling into a multi-day route, the Spearfish delivers a calm, predictable ride that lets us stay focused on forward progress.

Underneath that smooth ride is Salsa’s Split Pivot suspension platform, offering adjustable rear travel and active braking performance that shines on technical climbs and long descents alike. The carbon frame balances stiffness and comfort, while thoughtful frame features like top tube mounts, multiple bottle positions, and molded protection support self-supported adventures as well as race-day efficiency.

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.
