Radar Sport
Radar: A system for detecting the presence, direction, distance, and speed of surrounding conditions.
The dirt is your environment. Radar is your frequency for feeling it. Agile, composed, sharp, and rugged, Radar is an apparatus for experience. If you want to unplug from the machine and remember what it means to explore the wild, this is your signal.

The Radar Calls You Home
When conditions stagnate, the Radar keeps you going.
Movement maintains hope when the dirt turns to mud, the skies close in, and the rain won't stop falling down.
Off-Road Geometry in Butted Chromoly Steel
A frame that knows the road, so you can be the judge.
Radar’s geometry is created for preservation when the road gives more than it takes. As dirt washes away, paths blur, and progress feels immovable, the foundation remains something you can believe in.
Tubeless-Ready for Lower Pressures
Not every crossing moves on your schedule.
WTB tubeless-ready rims coupled with WTB NineLine 29 × 2.25” tires, allow lower pressures for consistent contact when movement slows and surfaces saturate. Clearance for up to 29 × 2.4” tires keeps growth possible when patience, not speed, explain the ride.
Equipped for Extended Coverage
Built to support a wide range of field operations.
Five bottle cage mounts, rack and fender mounts, and triple-mount positions on the seat stay and fork allow our Radar Sports to carry the equipment needed to stay on assignment longer. From water and tools to bags and supplies, the system is designed to adapt to changing demands without compromising mobility or focus.
Signal in Motion
A dependable transmission built for sustained forward progress.
A Shimano Deore Shadow Plus rear derailleur paired with a wide-range Shimano Deore 10-51T cassette delivers smooth, reliable drive across varied terrain and long routes. An alloy 36T crankset keeps cadence controlled and power predictable, resulting in a drivetrain designed to move the sport forward without interruption.
