On my scales;
32 DT 14mm brass nipples are just under 32g.
32 Revolution spokes at 258mm are 137g.
Stan’s Olympic 26″ 343 and 344g.
Chris King ISO rear hub (ally freehub) is 335g
Chris King ISO front hub is 166g
So actual (not claimed) Stan’s Olympic on Chris King with Revolution spokes are; 1526g. (accurate to within 1.5g) Reduce to just under 1500 for ally nipples.
However these wheels don’t need an inner tube nor UST tyres. Just a 7g valve, a 5g yellow plastic rim-strip and about 50g’s of Latex.
Some of these manufacturer claimed weights look a little optimistic.
