Now, there is no limit to the cockpit setup for your classic roadie, tourer, mtb, or any other bike with a 1″ threaded steerer. These stems feature a simple 2-bolt removable faceplate for use with any and all handlebars including modern bars with 31.8mm clamp diameters and “alt-bars” such as our Crazy Bar. The 90 degree extension makes for a bit of rise without looking out of place on a custom build.
