Overview
The Norco Revolver 120 Gen 4 is Norco’s dedicated cross-country race bike, the shortest-travel full-suspension model in the lineup. With 120mm of front travel and 115mm of rear travel, the Revolver 120 prioritizes light weight, pedaling efficiency, and speed above all else. Built on the same carbon Flex-Pivot platform as the Revolver 130, the 120 runs 29-inch wheels and is available in five sizes (1–5) with builds ranging from the SE (Shimano electronic) to the C1 (top-tier XTR) and C2.

The Revolver 120 features a 66.5° head angle — half a degree steeper than the 130 — reflecting its more race-oriented character. Seat tube angles range from 75° (Size 1) to 76° (Size 5), and reach spans 422.5mm to 522.5mm. Chainstay lengths progress from 422mm to 438mm. The 338mm bottom bracket height is 4mm lower than the Revolver 130, contributing to a lower center of gravity and increased stability. Stack ranges from 589mm to 625mm, keeping the rider in an efficient, forward position.

Geometry Analysis
The Revolver 120 is the more XC-focused sibling to the 130, and the geometry reflects this. The 66.5° head angle is still very progressive for a 120mm XC bike — many competitors run 67°+ — but it’s half a degree steeper than the 130, favoring quick steering response over descending stability. The 75°–76° seat tube angles are slightly steeper than the 130’s (74.5°–75.5°), keeping the rider more efficiently positioned over the pedals for sustained seated climbing. The 338mm BB height is remarkably low for a cross-country bike, providing excellent cornering stability and a planted feel. Reach numbers are identical to the 130 (422.5–522.5mm), meaning sizing translates directly between models.
Ride Characteristics
The Revolver 120 is a pure XC race bike with trail-capable geometry. On climbs, it’s in its element — the Flex-Pivot suspension is incredibly efficient, the light frame weight keeps momentum high, and the steep seat angles put power directly into the pedals. The 115mm of rear travel provides just enough compliance to maintain traction on rough XC courses without adding unnecessary weight or complexity. On descents, the Revolver 120 is surprisingly capable thanks to its progressive geometry — the 66.5° head angle gives it far more confidence than traditional XC bikes on technical terrain. The short chainstays and low weight make the bike nimble and responsive, ideal for threading through tight singletrack. However, this is still a 115mm-travel XC bike — sustained rough descents and big drops will find its limits faster than the 130.
Key Specs
Frame: Carbon. Wheel Size: 29″. Travel: 120mm fork / 115mm rear. Suspension: Flex-Pivot. Sizes: 1, 2, 3, 4, 5. Drivetrain: Shimano XTR Di2 / Shimano XT / SRAM X0 Eagle Transmission. Fork: RockShox SID Ultimate / RockShox SID. Shock: RockShox SIDLuxe. UDH Compatible.
What’s New vs Previous Generation
The Gen 4 Revolver 120 is a ground-up redesign sharing the new platform with the Revolver 130. Key changes include the Ride Aligned five-size range (previously four sizes), UDH compatibility, updated Flex-Pivot kinematics with improved anti-squat and leverage ratio, and modernized geometry with a slacker head angle (66.5° vs 67.5° on Gen 3). The frame is lighter than the outgoing model and features improved internal cable routing.
Who Should Consider This Bike
The Norco Revolver 120 is built for XC racers, marathon racers, and fitness-focused riders who want maximum efficiency with the safety net of full suspension. If you race XC — from local series to UCI events — and want a bike that climbs fast, handles technical features with confidence, and weighs next to nothing, the Revolver 120 delivers. For riders who want more descending capability or regularly ride aggressively technical terrain, the Revolver 130 or Optic would be better choices.
Comparable Models
The Revolver 120 competes with the Specialized Epic 8 (120/120mm), Trek Top Fuel (120/120mm), Santa Cruz Blur (120/115mm), Giant Anthem (120/120mm), and Yeti ASR (120/115mm). The Revolver 120’s 66.5° head angle is among the slackest in this XC class. The Epic 8 is the closest overall competitor with similar travel and geometry philosophy. The Blur and ASR are slightly more race-focused, while the Giant Anthem offers Maestro suspension at competitive pricing.

Frequently Asked Questions
What is the travel on the Norco Revolver 120?
The Norco Revolver 120 has 115mm of rear travel paired with a 120mm fork. This is one of the shortest-travel full-suspension configurations available, optimized for XC racing efficiency.
How much does the Norco Revolver 120 weigh?
The Revolver 120 in the C1 build weighs approximately 23-24 lbs depending on size. The lightweight Flex-Pivot suspension and carbon frame contribute to competitive XC race weight.
Is the Revolver 120 the same frame as the 130?
Yes, the Revolver 120 and 130 share the same Gen 4 carbon Flex-Pivot frame. The difference is in the fork (120mm vs 130mm) and shock tune (115mm vs 120mm rear travel), which creates slightly different geometry due to the changed front axle height.
What is the head angle on the Norco Revolver 120?
The Revolver 120 has a 66.5° head tube angle, which is progressive for a cross-country race bike. This is half a degree steeper than the Revolver 130’s 66° head angle.
Can I race XC on the Norco Revolver 120?
Absolutely. The Revolver 120 is Norco’s dedicated XC race bike, designed for UCI-level cross-country racing. The Flex-Pivot suspension provides excellent pedaling efficiency, and the lightweight carbon frame is competitive with the best XC platforms on the market.
