Tubeless On The Cheap ?

Has anyone tried this, specifically the using of your valves off your old tubes ? (at 4 minutes into the video)
I'm thinking of converting my road wheels with 80 mm valve stems.

Question for an old newby, what stops the sealant in tubeless from blocking up your valve ?

road tubeless requires specific tires and rim shapes

Ran valves cut out from old tubes on mtb for years with no problems. The sealant never blocked the valves, stays liquid until contact with the outside air I guess.
Yeah I would think a bit more carefully about running ghetto tubeless on road wheels.

I was up for new tyres, but thought I might get away with the existing rims. Maybe not :huh:
I've got a pair of Shimano RS 81 C50 and a pair of RS 010's

What tape do you use ?
My MTN Bike has tubeless ready rims, but wifey's MTN Bike doesn't. She has 27.5 Alex Rims.

I used 3M duct tape for my first set, but it was fiddly because I had to cut down the width, once done it worked ok but was lifting off a bit after a couple of years.
For my next set of wheels I got a variety of tapes (different widths etc) from http://tapespec.co.nz/ told them what I was using it for, it was all white and shiney lol, and it's still running sweet 4 years later.
Always ran non-tubeless tyres and some were 'thirstier' than others to get the initial seal.
