Description

The Radio Cobalt Pro XL is a race complete built on a lightweight 6061-T6 alloy frame with forged dropouts and an integrated chain tensioner, matched to a chromoly steerer fork with 30mm offset and a seamless 4130 chromoly bar.

Radio Raceline parts fill it out: fully sealed CNC alloy 36h hubs, double wall BX-32 rims, 175mm 3-piece forged alloy cranks on a sealed square taper bottom bracket, and 44/16 gearing through a KMC Z6 chain. A rear V-brake with a junior lever handles the stopping.

Features

  • Lightweight 6061-T6 alloy race frame. Forged dropouts with an integrated chain tensioner keep the rear wheel where you set it, and the alloy build keeps weight off the gate.
  • Crisp 44/16 gearing. A 44T alloy sprocket and 16T ATA chromoly freewheel give the punch you want down the first straight.
  • Fully sealed Raceline hubs. CNC alloy 36h hubs on double wall BX-32 rims, with a flip flop rear so you can run the gearing you prefer.
  • Chromoly cockpit up front. A seamless 4130 chromoly bar, an Arise Cobalt 50mm toploader stem and a chromoly steerer fork stand up to race day loads.
  • Rear V-brake, junior lever. The Radio Raceline junior lever suits smaller hands and pulls a Raceline V-brake for control into the turns.

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.
