Guys

Im in the process of producing a new cycling light and looking to soon showcase my prototypes at at a number of cycling shows

Does anyone of a central point were all upcoming shows are listed in both the UK and USA? - and better still, is there anywhere which briefs what each show will be about ie, shows to the public/trade/new brands/new products/

There are so so many options, im a little unsure as to where to start

Many thanks, much appreciated
