I'm cleaning my room today. It's where I sleep; it's where I build wheels; and it's where I store wheels, rims, hubs, and spokes. I've got other work to do, but it's not as much fun as wheel building. So to procrastinate, I decided to measure the internal/external dimensions of the rims on hand.
Yoeleo U shaped 25 mm carbon clincher
25 mm external/18 mm internal
Yishun 23 mm carbon tubular
23 mm external
Gigantex/Equinox carbon tubular
20.5 mm external
Velocity A23 clincher
22.8 mm external/17.5 mm internal
(This is equivalent to the HED Belgian and H Plus Son Archetype. The Pacenti SL23 measures 18.5 mm internally.)
DT Swiss 450 (double eyelet)
19.5 mm external/14 mm internal
Flashpoint FP60 clincher
18.4 mm external/13.4 mm internal
Can you say pinch-flat? Can you say 125 psi limit?
Velocity Arrowhead
20.25 mm external/14.2 mm internal
