Thanks. Actually, they are the ones building my wheels for me, but J ran out of rims. So, I had to order the rims from a third party. The Every Bike Tire store called me back, by the way, to confirm the order. Took a bit, but they seem nice on the phone.

By the way, the Aeroheads are available, but the inner diameter is only 14mm, so I asked to change them. It seems as if they will only run Comets or Stelvios, and they are only 20gm lighter than the Aeroheats.
