The Radar Maintains Signal
When conditions interfere, Radar keeps the report clear.
Receiving and transmitting keeps you comfortable as traction drops, temperatures fall, and the air itself will leave you frozen.
Off-Road Geometry in Butted Chromoly Steel
A cool steel chassis tuned for dirt-first riding.
Balanced geometry keeps the ride calm at speed and confident as weather and terrain transition unexpectedly. An English-threaded bottom bracket ensures long-term serviceability wherever the report leads.
Stability Through Freeze and Thaw
A grounded stance for surfaces under constant treatment.
A navigable road takes tons of work. Brine runs off, traction comes and goes, and the surface keeps changing beneath you. Tubeless-ready WTB rims and wide 29 X 2.25" WTB Nineline tires maintain traction through that pattern, with clearance for up to a 29 x 2.4” tire when conditions demand more. Freeze and thaw aren’t conditions—they’re a cycle.
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 Team 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 GRX 822 GS rear derailleur paired with a wide-range Shimano Deore 10–51T cassette delivers smooth, reliable drive across varied terrain and long routes. A Shimano SLX 34T crankset keeps cadence controlled and power predictable, resulting in a drivetrain designed to move the team forward without interruption.
