Overview
Come for the Party. Stay for the ride.
The Hoot Steel was designed with one goal in mind: Fun. Yes, with a capital F. This is a 140mm travel hardtail that brings the party to every line on the trail. The frame is the classic 4130 chromoly steel with custom tubing based on size to ensure the same smooth, comfortable, fun ride quality regardless of size. The Hoot Steel has fun engrained into the geometry, with a slack head tube angle, steep seat tube angle, low bottom bracket drop, and short chain stays. The result is a hardtail that balances the rider for confident riding on the steepest descents, while mixing in nimble handling for the trails that keep you on your toes. When everyone at the trailhead calls it a day, the Hoot Steel is ready for another lap.
Features
Custom 4130 chromoly steel frame with UDH-compatible dropouts for a tough, modern hardtail platform.
140mm RockShox Pike fork for a more capable trail feel than a basic XC hardtail.
Balanced, playful geometry made for confident descents, quick handling, and repeat laps.
Wide 29” trail setup with DT Swiss M 1900 wheels and Schwalbe Wicked Will 29 x 2.4” tires.
Dropper-ready build with a TranzX 31.6mm dropper and custom travel options.
