Tesa tape of your chosen width.
Lifeline valves or whatever is cheap ATM.
Bottle of Stan's, Orange seal, Muc Off or whatever is good and decently priced.
Tubeless kits come very short on tape and sealant, if you mess up the tape and need to redo or you need to top up sealant you'll be out of luck.
suggestion for a tubeless kit (e.g. 650b tyres) ?
wanna try hard this new world
thanks in advance
