Thanks everyone- few more things.
the aero wheels are clearance items, one set only. Just noticed the inner rim is only 17mm and the outer is 21. Would they require 23/25mm tires in order to avoid the mushroom effect?
The 34 hunts are wide rims, can easily take 28’s.
And yes on the tires. Currently on stock wheels that weight a ton, and riding 28mm armadillo winter tires. A pair of tubeless or latex tube Conti’s will be mounted to the new wheels.
Plus a lighter cassette and brake discs.
with that setup, the Hunt wheels will be 2.5#’s lighter than what I’m running now, Bontrager’s 1.9#s.
Both decent weight savings.
Tire width may be the deciding factor here.
