The Radix DLX features stepped up spec from the regular Radix. Assembled at Verde in Ohio, the DLX is built on the same 4130 chromoly Radix frame, but with a better fork, bars, tires, and sprocket. The Manitou Circus Expert 100mm air fork is lighter, provides more adjustment, and is spec’d with a 20mm front thru-axle. At $450 retail, this fork alone more than covers the cost of upgrading to the DLX. Other improvements include Pro Taper Stealth bars, Kenda 3-Sixty tires, and a US made Verde Neutra sprocket that steps the gear ratio up to 27-12T.
