Garmin Edge 205 - GPS bicycle speedo.
No wires, no fuss, very accurate, mount it where you want to, unclips in seconds.
Used mine for two years now, it's The Business, no f*cking about.

Most trials tyre makers seem to list a tubeless 2.75x21 front but as far as I know, no trials bike manufacturers seem to make use of them.
Why?
