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 XL 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

Disc brake ready rear end. Forged disc mount dropouts and a disc cassette rear hub let you move up to disc brakes later without changing the frame or wheel.
Hydroformed 6061-T6 alloy frame. It keeps the bike at 9.9 kg, and the integrated chain tensioners hold the rear wheel where you set it.
Fully chromoly fork. A butted 1-1/8" Cr-Mo steerer and Cr-Mo legs with 23mm offset take the biggest jumps on the track.
Sealed bearings, less maintenance. The FSA headset, BSA bottom bracket and both Xenon hubs run sealed, so there is less to service between race nights.
Radio Raceline parts kit. Xenon 170mm cranks, a 42T alloy sprocket and 16T driver for a 51.16" ratio, on sleeved Clipper Expert rims.

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.

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

Size	Rider height	Top tube
Micro (18" wheels)	Under 120cm	16.25"
Mini (20" wheels)	110 to 140cm	17 to 18"
Junior	120 to 150cm	18.25 to 18.75"
Expert	130 to 170cm	19.5 to 19.75"
Expert XL	145 to 170cm	20 to 20.75"
Pro	150 to 175cm	20.25 to 20.75"
Pro XL	165 to 180cm	21 to 21.25"
Pro XXL	170 to 185cm and up	21.5 to 21.85"
Pro XXXL	175cm and up	22"
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.
