Grenoble06: Six Day Tech
No other bike in pro racing gets as much time lavished upon it as a Six Day machine. A good mechanic needs a couple of hours per bike per day to do the job properly. On the face they're simple devices, with no brakes or gears to worry about. But these rigs are subject to the highest stresses with constant high speed, sudden changes of direction and those unforgiving G-forces from the steep bankings every couple of seconds.
