Inspired by Pivot's race-proven geometry of the downhill bike "Phoenix", the new Firebird 29 combines one of the longest reach masses on the market with 431 millimeter short chainstays. It also has an extremely low center of gravity. These elements are intended to give the new Pivot model both a very smooth ride at high speeds and a nimble riding style in winding terrain. Thanks to its low weight and pedal-friendly geometry, the bike should also climb very well.

The carbon frame of the Firebird 29 offers 162 millimeters of suspension travel controlled via the proven DW-Link and weighs only 3.2 kilograms without shock. However, it should meet the same high standards of strength and stiffness as Pivot's World Cup downhill race bike "Phoenix". Furthermore, the frame has an adjustable geometry and a stable rear triangle that offers plenty of tire clearance. Depending on your taste, you have the option of riding both 29 and 27.5 wheel and tire combinations. The rear triangle accepts tire dimensions up to 29x2.6 or 27.5x2.8 inches.

As already mentioned, the geometry of the Firebird is similar to that of the downhill bike. Pivot relies on a long reach and short chainstays. The reach is 475 millimetres, while the top tube length for size L is also quite long at 648 millimetres. The head angle of the Firebird 29 is 65 degrees and can be raised to 65.5 degrees using a flip chip. The seat angle can also be adjusted between 74.5 and 75 degrees.

Boost was yesterday

When it comes to the rear wheel axle, Pivot is not satisfied with the standardized approach and follows the motto "wider is better". The new axle standard is called "Super Boost" and is a whole 157 millimetres wide. Together with the wheel, this gives the rear triangle 30 percent more stiffness compared to the Boost 148 version.

The rocker arms of the rear triangle are also broadly supported and fitted with durable bearings. This also feeds a versatile, adjustable Fox X2 suspension element with shocks. Depending on the version, a Fox DPX2 damper also works on the shock. The Float 36 suspension fork also comes from Fox and offers 170 millimetres of travel.

Integrated details

Pivot hides the cables and lines almost completely inside the frame. They are clamped as they enter and are routed out to their destinations in the middle of the rear triangle. Incidentally, the rear triangle is protected against external impacts at the neuralgic points with perfectly shaped impact protectors.

The "container" for the Di2 battery is also interesting. The battery for the electronic shifting system is hidden in the down tube above the bottom bracket. A bottle cage can be mounted directly above it. Due to the arrangement of the shock, there is no space for a bottle in the frame triangle.

The new Firebird 29 is available in two color variants - Sandstorm with orange highlights or Steel Blue with yellow highlights. There are three model variants in two versions each: Team, Pro and Race Build each with Sram or Shimano, from XX1 Eagle and XTR to GX1 Eagle and XT/SLX.
