Ummm.. you can pick up a sub-1,000 gram carbon tubular wheelset for less than $600. New.
Not only would you shave a pound of rotating mass, but you'd have the tubular advantages of no pinch flats, no rim strip failures, and the ability to ride your tires at pressures anywhere between 50-170 psi.
Plus tubular rims are far more resistant to impacts, and if necessary, you can ride a flat tubular in relative safely.
Why is everyone so fussed about getting little glue on their hands?
