Nevertheless, once these problems are overcome, the belt drive really comes into its own:-

Totally clean running, as the belt does not need lubrication at all.

Silent operation

A belt will usually last 2 or 3 times as long as a chain.

The other main factor is that derailleur gears cannot be used, so belt drives will consequently be restricted to single speed or internal gear hub bikes. These internal gear hubs are getting better all the time - in reality they are now available with up to 11 ratios.

To cite an example, the SUB 10 from Scott features a Gates Carbon drive (one of the most popular). Together with an 8-speed Alfine hub, the SUB 10 as a consequence is a high-performance city and commuter bike - you can arrive at the office or school without having to be concerned about grease and oil on your daytime clothes.
