so im going to buy a 60-80mm wheel but the deepest wheels ive had were 48's and ive always used a presta valve adapter to make a presta into a schrader valve but as I was looking at the extenders there where no threads on the pumping end can someone please explain what I could use?

These would be easy.

If understanding correctly, just grab one of the little adapters for pumping if dealing with schrader pump. They cheap.

whoa, that's a long sentence

ive been using those but if you look at the valve extenders there is no thread to thread it on

google helped me find a presta valve extender that has threads.

wow thanks mike but i was still wondering why some arnt threaded is there an adapter that isnt threaded?

No, you'd need to use a different pump made for presta valves.

yes, get a presta pump.

re: valve extenders. put a bit of teflon tape on the threads joining it to the tube valve...leaks there will drive you crazy.
