Anyone who experiences the silence and smoothness of a belt drive will be won over. Efficiencies are well up there and there are now loads of bike companies now offering them (admittedly small companies - bigger companies are always slower to catch up). Chains are good for that last 0.05% performance that racers demand, but for the rest of us, I predict belts will become more and popular. Except that is for people who LIKE to have a tribal chain tattoo, on their legs/trousers/pants
