Description

The Radio Xenon Expert XL is for riders stepping up their race game, with lightweight alloy construction and pro level components. The hydroformed frame and chromoly fork keep things stiff and responsive, while the longer 20.5" top tube adds stability through high speed sections.

A race tuned drivetrain with a 41T sprocket, 170mm cranks and a 16T sealed cassette driver delivers power efficiently, and Tioga Power Block tyres look after grip and roll. A rear disc brake and a wider, more aggressive cockpit round out a bike dialled for control and confidence.

Features
  • Longer 20.5" top tube. The extra length adds stability through high speed sections, which is what riders stepping up their race game are after.
  • Hydroformed 6061-T6 alloy frame. Forged, disc brake mount ready dropouts and integrated chain tensioners hold the rear wheel exactly where you set it.
  • Race-tuned 41T gearing. A 41T alloy sprocket, 170mm 3pc cranks and a 16T sealed cassette driver make for strong, efficient power delivery.
  • Rear disc brake. The Arise Xenon disc brake and lever give the control and confidence to push harder every lap.
  • Wider, more aggressive cockpit. 6061-T6 alloy bars, a 50mm Arise Cobalt toploader stem and 139mm clamp-on Xenon grips, rolling on Tioga Power Block tyres.

Assembly information

Your race 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
  • Spin the rear wheel and check the rotor runs clear of the calliper
  • Check the brake and tyre pressure before the first ride

Disc brakes: keep your fingers off the rotor and pads, because oil from your skin contaminates the braking surface and takes the bite away. If the rotor rubs, loosen the two calliper bolts, squeeze the lever, then tighten them again with the lever held on. Bed the brake in with a few firm stops before you race it.

Tools: Allen key set and a 15mm spanner for the pedals. Check your axle hardware, since race bikes vary between bolt-on nuts and a thru-axle.

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.
