This classic Diamondback mtb frame is in great condition and the perfect bike to convert into an off road touring bike or adventure bike. We’ve done just that with drop handlebars and a 2×10 speed drive train. The top tube measures 59cm and the seat tube 53cm. It’s therefore a medium/large frame. It has 26″ wheels meaning plenty of room for mud and mudguards, even with chunky mountain bike tyres like these. As with all our refurbs it comes with a three month warranty.
