It seems that all of the new KH rims are drilled for using shrader valves, I was curious if anyone could give any insite in to why this is.
I for one deffenatlly perfer Presta and the tubes deffenatly seem easier to come by for wide 700c wheels.
There are adapters that will let you properly fit a presta stem in a schrader sized hole. Wheels Manufacturing makes one that should work well with the double wall KH rim. Here’s a link to it over at Bike Tools Etc.
