Hot on the heels of the news that Standard is debuting an OS20 125r race frame, we learn that legendary frame builder, Gary Turner, is also testing an OS20 race bike with a 22″ top tube!

With GT Bicycles already having a complete OS20 bike (the Pro Series XXL OS20), Standard releasing its OS20 125r, and other “artisan” brands like Stout and Indust producing custom OS20 frame and fork sets…this wheel size is finally (after almost four years after its introduction) starting to see some momentum.
