Belt drive fixed

I hadn't thought about weight saving (what sort of weight weenie am I). How much weight is saved?
Do the chainrings/cogs weigh more which offsets save on belt over chain? Suppose the most you could save would be around 200g wouldn't it if a belt was 100g?

The cogs and chainrings are made from a thermosetting resin (from inspection) and do save some weight. Although as alu cogs and chainrings are pretty light its not a massive weight saving.

Looks like 200g was pretty spot-on (Kerley = uber weight weenie)
