The future drive scene might be coming together. According to bikebiz.com the top belt manufacturers have agreed to standardize the size specifications. The carbon belt has started to gain exposure as a replacement for the drive train.

From the article:

The four main Poly Chain players meet to agree standard width and pitch

It could have been Blu-Ray versus HD DVD, Betamax versus VHS, or a width replay of the 19th Century Gauge War between Brunel versus Stephenson.

Instead, heads have been banged together and the fledging synchronous Chain Drive market will now operate to a width of 10mm and a depth of 11mm. Transmission multi-national Gates of the US has been working with Orange in the UK and Carbon Drive Systems of the US, an off-shoot of Spot Bikes. The US Gates factory was producing carbon-corded belts in a different width and pitch to the UK Gates factory.
