converting rear wheel HED 3 to front
So i found rear hed 3 650c road wheel on ebay and i wanted to know if it would be possible for me to convert it to a front wheel to use it for my fixed gear. ive read other forums but im not too sure. i heard it wouldnt work if it was a cassette, but would work if it had a screw on block. i dont know what a screw on block is though. heres some info from the guy selling--"The wheel does not include a skewer or cassette. This wheel is a clincher. 8/9/10 speed compatible." So would it be possible and what would i need to do it?
