pre-built 20" 451mm wheelsets?
 

a lot places seem to carry 406mm wheelsets, but does anyone know of a good source for 451mm wheelsets? it's for a fixed/ss project i'm working on.

This is just a guess. Probably Gaerlan, or Thor USA?

Go to: http://www.gaerlan.com/bikeparts/par...eel/wheel.html

Bike Friday has them or can custom build them. Roger

i've seen sets being sold by BMX dealers on the net. try searching "bmx mini wheels" or "bmx racing wheels" thats what they call the ISO451 types

this is one example though out of stock

thanks for the replies. i'll give gaerlan or thor a try. i was initially hoping bmx wheels would be the perfect solution, since they were readily available and cheap, unfortunately some forum searching revealed that bmx hubs were unsuitable for running fixed.
