LS cx 700x32 tubes?

[RhinoRiot]

i'm throwing my rolf eshelon road wheels on my Singlecross cx bike, but with the deep rims i'm wondering if most people using aero wheels on a CX bike use valve extenders, or are able to find long stem tubes in a 700x32 variety??

[rocks in head]

I've been able to find them with 48mm stems... I use the weinmann DP-18s which are somewhat aero, probalby about the same depth, actually. they're 28-32 I think, but I use them on 35mm tires (which are probably closer to 38) I just asked at my LBS for the longer stems and they asked '48 OK?'

Your Shop can get Long valve'd 28-32s from QBP, I've had to order them for the ritchey/spinergy wheels I ride. I work at a shop and just ordered like 4 of them to have around.
