anyone know of a trainer like this (http://www.nashbar.com/profile.cfm?category=&subcategory=&brand=&sku=15431&storetype=&estoreid=&pagename=) that works with 20-inch wheels?

Here's one (http://www.danscomp.com/851016.php) from Dan's Comp that works with 20" and 24" wheels.

Wow that was fast. Thanks!
