Pro Bike Check: Aaron Chase’s Pivot Firebird park bike

At the Maxxis Summit this past weekend, Aaron Chase pulled all eyes to the rooftop of the Mulberry Gap barn as he climbed up then rolled down it, cleaning the jump not once, not twice, but three times. We caught it all on video, along with a quick bike check to see what he’s done to his Pivot Firebird. Images, both moving and still, below…

Aaron’s running Pivot’s new Phoenix handlebar with a Race Face 35mm ID stem. The bar pairs with Pad Lock grips, but Pivot used a much softer outer rubber to cushion the nerves on the outside of the palm.

The key customization on Aaron’s bike is the front brake line run through the headset cap and steerer tube. FSA makes one in their Gravity line that uses a separate hole from the bolt and altered wedge system, but this one looks like Brake Through’s BMX-style cable-thru-the-bolt design.

Suspension is handled by a Fox 36 Factory fork up front…

…and Float X2 Factory shock in the rear.

Drivetrain and brakes should be all Shimano…

…but Aaron just got his cranks in and hadn’t had time to swap them over. In the video he also mentions a rigid seatpost, but over the weekend he did have a KS dropper in there for a bit. The explanation? It’s really early in the season and not all sponsor parts have arrived, so there are a few mixes and matches until it’s dialed for event season.

An XT cassette and XTR rear derailleur handle shifting.

A very colorful SDG saddle, surprisingly, manages to match the colors on the bike.

Maxxis supplies the rubber, in this case tubeless ready DH casing High Roller II tires.

They’re fitted to DT Swiss EX wheels. Follow Aaron’s rides on Facebook here.
