Magnum CX - Cyclocross

“After many years of representing Tonic and a few years of racing cross on my first Magnum, I made the decision to form the Tonic Japan CX team and ordered team bikes from Tony. The frames were awesome. The 44mm HT with 1.5″ tapered fork combo were some of the first to appear in Japan. The custom team graphic on neon yellow was sensational. The bikes were light, stiff and handled incredibly. Since then, I have only changed the decals and the bike still looks and rides exceptionally well.”
