Description
The Radio Raceline Xenon Expert Disc is a mid-level BMX race complete for smaller racers who want the lighter Expert-sized platform with a factory disc brake rather than planning the conversion later.
The hydroformed alloy frame and race-focused component package are built for progression at the track, with the disc setup giving consistent rear braking while keeping the bike properly proportioned for an Expert-size rider.
A serious race bike for riders who have outgrown entry-level gear but not their actual bike size.
