Confused on what length of valve extension I need!
 

Just got my set of Flit carbon wheels and they are 50mm deep aero.

I see that extensions come in many different lengths. Suggestions?

The depth of the rim from the outside edge to the base of the valve is about 10 mm. You will want a bit more than that sticking out from the inside of your rim, so get ones with 55-65 mm valves.

thanks!
