This was a rush job – a four-person bike built in two weeks for a marketing roadshow.
It had S&S couplings fitted to make it a little easier to transport, and a beefy stand to hold it upright with four people sitting on it.
Gavin’s Racerunner was built from thin-wall Columbus Gara tubing, for a frame weight of around 4kg, and a total built-up weight of under 10kg.
The frame was built on a custom jig to be perfectly straight, and has adjustable fore and aft positioning of the saddle, and adjustable chest plate using a seatpost.
A series of axle inserts allow different wheels to be used, and the camber can also be adjusted.
Cost was £1500 for the frame, inserts, painting and assembly.
