Who makes sure the wheels turn smoothly during a six day race? The mechanics are the men who change the gears, stick on the tyres, endlessly polish the paintwork and pick up the pieces after crashes. They arrive first to build the bikes up and leave last after having stripped the bikes down for transit. What makes a man want to roam Europe, often driving a thousand kilometres through the night to get to the next race - or to get home? PEZ spoke to circuit spanner man, Dirk Dekeyser at the recent Grenoble Six.
