What do you need? Well, speaking from my recent experience of going tubeless, converting standard Bontrager 29er rims and tyres using a Stan's kit with rubber rim strips with built in valves, you might need access to a decent compressor to whack enough air in to get an initial seal. I had my LBS help out. If you are using your existing tyres, you might also find you need to buy a new tyre if, like mine, there was already a 1/4" long puncture in the tread that the fluid could not seal...
