iv know king uk to return a hub with missing parts ans rebuilt wrong, total muppets............ king best hub going ever for the money, i had a 2nd had 5 year old one for 3 years never had a problem, never skippled, and iv had a new one, only becasue of the stupid 6 gear rule in comps cus i wanted to ride some comps did i change, only problem iv had is the flangles tend to die after 3-4 years, due to alu fatiuge same as any alu hub shell, iv got a faily new one at the mo, only changed so i could get 32 wide trials rim and it slipped a couple of times on me, but after it was cleaned and beeded its fine, but as for best hub for trials im not so sure, i think a front freewheel is more suited i also have kings on my i drive, bothe 5 years plus old and still as sweet as the day they were made... at the end of the day they are not a trials hub, classic is light enough for a road bike, and strong enough for a down hill bike, well iso, same internaly, cant get better than that
