When your bike has cantilevers or V-brakes and you just need a smallish rack up there for a bag or basket or stuff-sack, this is the best choice. Even Mark, of Mark's Rack fame, uses it on his bike with cantilever brakes.

It has a threaded rod that mounts through the hole in the fork crown hole that isn't used because your bike has cantilevers, and then each lower leg of it clamps to the fork blade, using totally foolproof, reliable, cushioned, stainless steel, lightweight Nitto-made clamps and hardware.

It's easy to mount, it mounts solidly, and any bike with a hole in the crown can be made more useful with this rack.

No doubt there are some super fat forks there that it won't fit, but if the circumference of your fork blade at a point roughly 5 3/4-inches below the hole in the crown is within spitting distance of an inch, the rubber clamps will go around it.
