I just ordered a set of Jongbloeds last week.
I did an awful lot of checking, and they have everything I want. They are 17 inches, 9 inches front, 11 inches rear. 15.5 lbs.
I got the 301 centers, but they have Halibrand centers too. A real Cobra look.
The only downside is they are a little pricy. But you get what you pay for.
As with any light, racing type wheel, be extra careful on the street. Curbs and potholes become more intimidating.
