Pivot Firebird Pro X0 Eagle Transmission FOX Float X2

The Pivot Firebird Pro X0 Eagle Transmission FOX Float X2 is Pivot's enduro race weapon — a full-carbon 165/170mm bike built for the kind of terrain that ends other people's days early. With a 65-degree head tube angle, DW-Link suspension, and a Fox Factory chassis front to rear, the Firebird Pro is designed for riders who want to go as fast downhill as the mountain will allow, without giving up the ability to get themselves back to the top. This is the Pro build: X0 Eagle Transmission drivetrain, Fox Factory Float X2 rear shock, and DT Swiss XM1700 wheels with 350 hubs — a spec sheet that leaves almost nothing to upgrade.

The DW-Link suspension system — designed by Dave Weagle, whose linkage designs have won more enduro World Cup rounds than any other — is the core of what makes the Firebird's ride character distinctive. DW-Link is engineered to provide high small-bump sensitivity early in the travel while building through-stroke support as loads increase, all without the pedaling losses that plague multi-link designs that sacrifice efficiency for compliance. The result is 165mm of rear travel that actually uses the full stroke rather than running through it on the first hard hit. A flip chip lets you tune between progressive and linear damping curves depending on your riding style and terrain preference.

Pivot's Swinger Dropout system adds a dimension of adjustability that most enduro frames don't offer. Eight millimeters of chainstay adjustment lets you dial the rear center between a shorter setting — snappier, more playful, better for technical cornering and manual-based riding — and a longer setting that adds stability at speed on open, high-consequence terrain. It's not a gimmick; it changes the handling character meaningfully, and it's adjustable without tools at the trailhead.

The Fox Factory 38 fork (170mm, GRIP2 damper, 44mm offset) matches the rear shock's capability with top-tier damping control and the stiffness the Firebird's geometry demands. The Float X2 rear shock is Fox's full-featured enduro unit — fully adjustable compression and rebound in both high- and low-speed circuits. Between the fork and shock, this is a suspension package that rewards riders who know how to tune it and performs well even for those who don't. The Firebird is also FOX Live Valve Neo compatible for riders who want active suspension.

Pivot's Toolshed in-frame storage system — magnetic closure, clean integration, no rattling on rough terrain — keeps a multi-tool, tire plug, and CO2 accessible without a hip pack. Combined with SRAM's UDH (Universal Derailleur Hanger) dropout on the X0 Eagle Transmission build, the Firebird is as trail-practical as it is performance-oriented. SRAM Transmission means the X0 derailleur mounts directly to the frame without a separate hanger — no bent hanger, no dropped chain from a jammed derailleur, and a drivetrain that shifts cleanly under load.

Design Benefits

1. DW-Link suspension — Dave Weagle's linkage geometry delivers small-bump sensitivity and mid-stroke support without pedaling losses, making 165mm of travel feel active on everything from roots to rock gardens to full sends.
2. Swinger Dropout system — 8mm of chainstay adjustment lets you tune between a shorter, punchier rear end and a longer, more stable platform without tools. One bike, two distinct handling characters.
3. SRAM X0 Eagle Transmission — Direct UDH mount eliminates the derailleur hanger as a failure point. Shifts cleanly under load, resists chain drop, and is easier to service in the field than traditional derailleur setups.
4. Fox Factory 38 GRIP2 + Float X2 — Top-tier damping on both ends. GRIP2 offers independent high- and low-speed compression adjustment front; Float X2 matches it rear. Full factory-grade tuning capability in every ride condition.
5. Pivot Toolshed storage — Magnetic in-frame storage that doesn't rattle, doesn't require a hip pack, and doesn't compromise the frame's structural integrity.
6. Maxxis Assegai 29x2.5 — An aggressive, confidence-inspiring front tire with a tread pattern designed for enduro-pace cornering on loose and variable terrain.

Final Take

The Pivot Firebird Pro X0 Eagle Transmission is a complete enduro build with no meaningful gaps in the spec sheet. The DW-Link chassis, adjustable Swinger Dropout, and Fox Factory suspension give it a depth of tunability that most bikes at this price point don't offer. At $8,799 with X0 Eagle Transmission, Factory Fox front and rear, and DT Swiss XM1700 wheels, it's priced fairly for what it delivers. If your riding is enduro-paced — big descents, technical terrain, full commitment — this is the Pivot to be on.
