Tubeless on 50MM deep carbon rims?

[jackmen]

Anybody doing tubeless on 50 MM or deeper carbon rims? A question is How do you get the tubeless presta Valve to seal as I can only find valves that are 38MM long? You can get extenders but once the extenders are attatched to the valves there are no threads exposed to screw down and tighten the round nut on.

Can you get 60-70 MM tubeless presta valves for these deeper rims?

It'll work fine. You need to buy Stan's extenders and valves which are threaded.
On 38mm they stick out allot but no other choice, on 50mm they are about perfect.
