May have been asked before but finally catching up with the world and want I know do I need 35mm or 44mm valves??

Or are there cheaper alternatives that are just as effective/better?

Cheers

Either will work fine.

The valves that WTB and Superstar sell are better than Stans IMO- they have a bigger base so are easier to get to seal (*), and the alu ones are lighter, and purtier, and I think cheaper. So I use those.

(* OK, this is mostly about installation errors, Stans work fine as long as you get the tape right. But lots of people don’t)

Specialized valves from Evans (or elsewhere) work just as well and are cheaper
