Is there an easy way to identify a sealed hub from a non sealed on ? ie: Without taking the centre cap off ? I have various Araya/Ukai spoked wheels, some say 'Sealed' on the hub, but they look the same as another pair that were sold to me as un-sealed?
I first thought that sealed ons have a black plastic centre inside the silver cap? but I also have a sealed pair without this ?
hmmmmmmmmmmmmm - sorry to ask a stupid question
.....but I need to know !
