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.
