Tubeless valves that do not clog

Bought one last year and it is still going strong.

The cheaper one is fine for commuting.

Spend the money on tyres before anything else.

Mine broke after six months, would not buy again.

Try before you buy if you can, fit is personal.

Worth every penny for daily riding.

I have a spare you can borrow to test.

Look for last season's model, often half price.
