Description

Building upon their ever increasing successes, the Radio Xenon range is solidifying itself as a trusted mid level complete race bike. The Radio Xenon Expert Bike comes with an array of race winning components, including disc brake ready dropouts.

The frame is manufactured from hydro-formed 6061-T6 alloy, with forks fully built from chromoly, from the steerer tube, to the fork legs. This means that it's a light bike, yet with tough forks, so that it can take on the biggest jumps that your rider can throw at it.

Sealed bottom bracket and hubs keep maintenance down to a minimum, with quality Radio Raceline components fitted across the bike. The ever-dependable Tioga Powerblocks are employed to keep this rocket rolling and sticking to the race line in the corners.

This BMX race bike is perfectly suited to the rider starting off their racing journey at a club level, whether they are starting off at a club's training sessions, or tackling club racing.

And when they are ready to move their racing up a notch or two, then the Radio Xenon is ready to move with them with a disc brake ready rear disc hub and dropout set up. This means that you can upgrade the brakes or wheels as they take things a little more seriously.

Features

Light alloy frame, chromoly fork. Hydroformed 6061-T6 keeps the bike at 8.19kg while the fully chromoly fork legs and steerer handle the bigger jumps.
Disc brake ready dropouts. Forged dropouts and a disc cassette rear hub mean you can add discs or better wheels as your racer gets serious.
Sealed bearings front to back. Sealed Xenon hubs and a sealed BSA square taper bottom bracket keep the maintenance down between race meets.
Tioga Powerblock tyres, 20 x 1-3/8". The proven race tread holds the line through the corners and keeps this one rolling on the straights.
42x16 gearing on 165mm cranks. A 54.88" ratio through forged and CNC alloy Xenon cranks suits an expert sized rider working on gate starts.

Assembly information

Your bike ships mostly assembled in the box. Finishing it takes most people 10 to 20 minutes with basic tools, and the video above walks through every step.

Fit the handlebars and line them up with the front wheel
Fit the front wheel, pedals and seat post
Check the brakes and tyre pressure before the first ride

Tools: Allen key set and a 15mm, 17mm or 19mm spanner for the pedals and axle nuts (bikes can vary between these three sizes). A socket is needed if installing pegs.

Rather have it done? Ask us about extra assembly before you order, or any local bike shop can finish the build for a small fee.

Race frames are sized by class, and the class you ride is set by rider height rather than age.

Micro (18" wheels)	Under 120cm	16.25"
Mini (20" wheels)	110 to 140cm	17 to 18"

Pro XXXXL	180cm and up	22.5"
Cruiser (24" wheels)	175cm and up	21.5" and up

Heights overlap between classes on purpose. Where you land in two, a growing rider is usually better on the larger, and a rider who wants the bike to turn faster on the smaller. Some brands label the Pro size Pro L, with the same fit.

How to measure

Stand your rider against a wall in the shoes they ride in, heels flat, and mark the top of their head. Measure from the floor to the mark.

Between two sizes and still growing? Take the larger size.
Racing gates and wanting the bike to turn faster? Take the smaller size.
Top tube is the number that actually changes the fit, so compare it against the bike they ride now.

Not sure? Send us their height and we will tell you what we would put them on.
