Suggest high-flow / good presta valve cores?

[tbgallant]

Hey all,

I've purchased lots of presta valve cores on Ali, but I find most of them are pretty low flow/poor quality.  Anybody have any vendor suggestions/links for 'good' presta valve cores (bulk of 10 more or is fine)?

Thanks

First I drill the hole with drill bit up the largest I can then cut the final part of the valve in order to reduce clogging.

Alternatively I'm using E13 valve https://theloamwolf.com/reviews/components/review-ethirteen-quick-fill-plasma-valve/
