just took me about 3 or 4 hours to change out a hub and id have to say the hardest part isnt getting it true from side to side but not getting any humps
ive never used a jig or tensiometer but i would love to try them
always used a frame with a pencil but these road rims i got (they came with the cheap bike) werent as easy as the bmx rims i used to work on 20 yrs ago
