How do you get two bikes from the parking area to the pits in a UCI race ? Hook 'em to this rig. The parking lots are often far from the pit at a race course and usually time is of the essence so this bike was the mechanic's solution to the issue as well as a platform to use the new 650B dirt tires from Kirk Pacenti at Bikelugs.com . These wheels are larger diameter that 26" but not as large as 29er wheels and easier to build around. The frame will have the towing/transporting rack but other racks will be built for more conventional uses. The frame is a modified 'Alfie" with a longer wheelbase and room for larger tires.
