A svelte but burly headset with standard sealed cartridge bearings in the top cup, but a double row cartridge on the lower cup where the most of the stress is. Great upgrade for street bikes and "all-mountain" bikes alike. A collaboration between Soma, Tange-Seiki and Kyoto Loco (a festival celebrating the bike messenger lifestyle).
