I’m sure this has been moaned about before but even so, I think it’s worth repeating.
Genuinely question – why are tubeless valves so expensive?
It’s an inner tube (cost, ~£3 – £5), minus the tube.
So why are the cheapest Stan’s valves I can find online £12.50 a pair, and why are there (much) cheaper equivalents. Cheapest no-brand ones on eBay are £9 a pair. I can buy 3 tubes for that. So why is no-one under-cutting?
(Yes, I know I could cut some old tubes up, but this will be my first tubeless experience so I want to lessen the risk of cock-ups, and all the knackered presta tubes I have are knackered because of the valve.)
