Pivot Firebird
165mm Rear • 170mm Front • Hollow Core Carbon
Rise & shred. The enduro-bred Firebird is built of carbon and courage — nearly bottomless dw-link suspension that pedals with surprising efficiency and descends with uncompromising authority. This fifth-generation Firebird adds in-frame Toolshed storage, the patented Swinger Dropout for adjustable chainstay length, a progression flip chip, and XS–XL sizing. This build runs the mixed-wheel setup (29" front / 27.5" rear) with alloy wheels.
Key Highlights
Hollow Core Carbon + dw-link
165mm of rear travel with size-specific carbon layups. The longer, Phoenix DH-inspired dw-link maximizes rearward wheel path to erase square-edge hits while staying efficient under power.
Swinger Dropout & Flip Chip
8mm of chainstay-length adjustment, fully UDH and SRAM Transmission compatible in either setting. A separate suspension flip chip lets you choose a more progressive, poppy feel or a more linear, planted one.
Fox Factory Suspension
Fox Factory 38 fork with GRIP X2 damper at 170mm, paired with a Fox Factory Float X2 rear shock.
SRAM X0 Eagle Transmission
Wireless 12-speed T-Type shifting with the X0 1295 10-52t cassette and X0 DUB cranks.
Toolshed Storage
Clean, quiet in-frame downtube storage with integrated magnets and a strap loop; Toolshed bags included.
Gravity-Ready Build
SRAM Maven Silver 4-piston brakes on 200mm HS2 rotors, Newmen Beskar 30 alloy wheels on DT Swiss 350 hubs, Continental Kryptotal Enduro tires, Fox Transfer Factory dropper, Phoenix Team carbon cockpit.
