I literally just finished going tubeless about 20 minutes ago. It was pretty straightforward. Although I did already have Stans Arch Ex rims with yellow tape, and Spesh Purgatory 2bliss tyres.
It was a simple task of removing the tubes, screw in the tubeless valves, fit tyres, fill with stans fluid through the valve core and pump up. Literally worked and sealed first time on each wheel (with a bit of sloshing around of the fluid mind).
Also a decent weight saving for me – my Conti tubes weighed around 200g, approx. 50-60g of fluid and valve went in, means about 140-150g per wheel – worth it without even trying the grip/less punctures benefits
