Radio Sonar Front Hub delivers a no-nonsense build for street, slopestyle, and dirt riding where front brakes aren't needed. The 606-T6 alloy shell keeps weight down to just 320g while the oversize sealed stainless bearings handle the demands of brakeless setups. Compatible with both 110mm x 20mm and 100mm x 15mm thru axles with included adaptors, it's engineered for a stronger, lighter wheel build.
