The rack mounts in the outer hole and the inner hole is used for clamping to the seat stay.

Take this length, the circumference, and divide it by pi (3.14). Available sizes: 14mm, 16mm, 18-19mm, 21-22mm, and 24-25mm. (If your seat stays are in between sizes, use the next larger size, with a shim)

Too big

Too big and you don’t sell a smaller size.

Good quality seat stay mounts

These mounts are often the only way to mount a rack to a track frame or other frame without rack mounting provisions. They're certainly durable and have handled years of repeated abuse. I reckon that Campfire Cycling is the only place to find them locally as well.

Perfect!

After adding a "shim," fashioned from a bike innertube, the Tubus clamps transformed my non-eyelet road bike into a roadworthy tourer... of course, there were some other mods, as well. Great product and service.
