For the ultimate in adventure-ready performance, a custom steel bike is a great choice. The mainstream bike industry still considers essentials like lights and fenders ‘accessories,’ and ideas like the shock absorption of fork blades haven’t entered the collective consciousness yet. All these features can be incorporated into a custom steel bike. Yet many framebuilding parts were designed decades ago and don’t work well for modern all-road bikes. So we made our own. Our frame tubes are custom-drawn by Kaisei in Japan to our specifications. Our dropouts and frame fittings are designed for current components. Our parts help builders make bicycles that combine superior performance with a beautiful finish.
