Hi all,

Just wondering a couple of things. I'm about to make the Tubeless conversion for my 650b MTB. I've bought the liquid and the tubeless valves - the setup is 'tubeless ready'. My pump at the moment is a small mini pump - for touring with Tubeless is it worth taking something more powerful?

I would have thought if I needed to resit the bead it would be because I am changing the tire? I plan on doing the GDMBR - I figured the worst case scenario I'll run a tube - so I don't understand why I need a powerful pump? - I'm not planning on doing a tubeless conversion in my hotel room - opinions?

Do you take spare valves? Or just valve cores? I'm a bit confused about this - people say they can get gunked up or lost - I assume this means the small inner part of the tube which is removable using a valve tool? As for the tool itself - will any cheapo valve core remover from eBay work or should I buy the branded Stan/Park tool which seems expensive to me.

One last thing - does anyone have experience with Orange Seal Endurance sealant? I know these come in 4oz, 8oz bottles with an injector - can one buy an injector bottle and use refills for that or is a one-use only thing? They say for a 650b I need 1oz of fluid. Have you found this to be the case?

Thanks in advance
