Pivot
Firebird MXTeam XX Eagle Transmission Podium MX
The Pivot Firebird MX is a dedicated enduro race bike built for aggressive riders who prioritize speed and precision over passive comfort. For its fifth generation, Pivot retained the 165mm rear and 170mm front travel but overhauled the chassis to be highly adaptable to different tracks. The frame now features a Swinger dropout for chainstay length adjustments, a dedicated suspension progressivity flip-chip, and a high/low geometry flip-chip. Pivot also added integrated downtube storage and an oversized head tube to accommodate reach- or angle-adjust headsets. While it climbs with the efficiency of a shorter-travel trail bike, the Firebird remains an uncompromising race machine on the descents. It demands an active, forward-biased riding style and rewards high-speed commitment, making it best suited for seasoned racers rather than casual trail riders looking for a forgiving platform.
Spec sheet.
Every component shipped with this build.
Geometry & fit.
5 sizes published.
The Firebird’s geometry is heavily adjustable, allowing riders to tune the fit and handling to specific tracks. The frame utilizes a slack 63.4-degree head tube angle and a steep 77-degree seat tube angle. This combination places the rider in an upright, efficient seated position for long climbs, keeping weight centered over the bottom bracket.
On descents, the bike’s character is defined by a bottom bracket that sits lower than the previous generation. This low center of gravity encourages an attacking posture and helps the bike carve tight arcs, though it does require careful pedal timing on technical climbs to avoid strikes. The Swinger dropout system offers eight millimeters of chainstay length adjustment, letting riders choose between a shorter, more agile rear center or a longer setting for high-speed stability. Reach figures span from 410 millimeters on the extra-small to 500 millimeters on the extra-large, and the oversized head tube allows for further reach or angle modifications via aftermarket headset cups.
Where the handlebar sits relative to the bottom bracket — the single most important fit pair.

The lineup.
10 builds, ranging $6,899 – $15,099.
Pivot offers the Firebird MX across a premium price spectrum, starting with the Ride tier and topping out with the Team builds. The entry-point Ride models feature Fox Performance suspension, DT Swiss M1900 alloy wheels, and either SRAM mechanical or GX Eagle Transmission drivetrains. These builds provide the same carbon frame features but use heavier, less refined components to keep the price relatively accessible.
The Pro tier represents the sweet spot for privateer racers. These models upgrade to Fox Factory suspension—including the highly tunable Grip X2 fork damper and Float X2 shock—along with DT Swiss XM1700 alloy wheels. Drivetrain options here split between Shimano XT/XTR blends and SRAM X0 Eagle Transmission, paired with either Shimano XT or SRAM Maven Silver brakes. Pivot also offers Pro and Team builds with Fox's electronic DHX Neo Live valve suspension for riders seeking automated damping adjustments.
At the top end, the Team builds spare no expense. They feature Reynolds Blacklabel carbon wheels with Industry Nine hubs, Race Face Era carbon cranks, and flagship drivetrains from Shimano or SRAM. Across all builds, Pivot specs Continental Kryptotal tires and its own Phoenix cockpits.
From the press.
4 reviews from the cycling press.
Reviewers agree that the Firebird MX is a demanding, highly capable race bike that requires constant rider input. The DW-link suspension and stiff carbon chassis create a highly efficient pedaling platform, with testers noting it climbs with surprising urgency. However, this rigidity translates to a firm ride on descents. The suspension is supportive rather than plush, meaning the bike needs to be pushed hard to perform. As one tester noted, the rear end feels "plugged up in a way that feels like it's eating energy" (YouTube), keeping the chassis settled at high speeds but transmitting feedback on smaller impacts.
When ridden aggressively, the bike is exceptionally precise. The lowered bottom bracket creates a "sunk into the bike" (YouTube) sensation that encourages riders to weight the front wheel and drive through corners. Testers praised its ability to change direction rapidly, noting that "railing corners feels awesome" (BikeRadar) when the rider is fully committed.
The primary tradeoff is a distinct lack of forgiveness. If a rider backs off the pace or gets lazy, the stiff frame and firm suspension can quickly lead to fatigue. Testers warned that the bike will "bang and bash you about" (BikeRadar) if you lose focus. Additionally, the stock Continental Kryptotal tires drew mixed reactions; they performed well in dry dirt but lacked damping and traction on wet, greasy roots, prompting recommendations for an immediate upgrade in certain climates.
