Well it has to have a splined hub because its a KH trials (unless it’s a norco but then it isn’t a KH) It is an '04 because of the alex rim and black frame. The '03s were orange and the '05s are blue and have a KH rim.
I just got a new Summit trials for $245. ( I know they aren’t made anymore, but it’s still new) With shipping of only $18, and no tax, that’s less than torker or and way less than a qu-ax trials, which is about $350 with shipping factored in. But all in all, the qu-ax or Torker dx is priced fairly low for a splined uni, so you can’t really go wrong.
