Roval wheels seemed like the ultimate, exotic competition bicycle wheel
when I started riding again in the mid-80's.
These feature streamlined hubs with strange lacing, bladed spokes with
a T head, hidden spoke nipples in their special rims.
This front wheel is 18 spokes - 9 laced radially per side
The rear wheel is 24 spokes - 16 laced cross one on the drive side and
8 radial on the off side.
They were more popular with the racers with sew-up rims.
