Are you looking for something lightweight, and want non machined sidewalls with color? The Aerohead is our lightest rim we offer, and you can now get it in a number of colors with or without machined sidewalls. It comes standard with our cut out flange track hubs, but you can always upgrade to a solid flange, hollow axle track hub. They are built up with stainless spokes, and brass nips the rest is up to you.
