My frame did have a third hole already. However, I had to make up an adaptor plate as the standard hole positions (Bottle cage and extra hole) made the swat box interfere with the rear shock. So, the adaptor plate bolts onto the frame (Existing holes), and the bottle cage and swat box bolt onto the adaptor plate (about 25mm forward of the existing holes)
Slightly off topic but... Why do cyclists have to wear an item of cycling clothing, usually those stupid little caps when they pick up their number from registration. I would never have known that they were cyclists, what with their smooth legs and the fact that they are at a cycle race registration
