Every set of Hope Hoops (Pro II + DT Comp) on ZTR rims I’ve had have always been pretty much bang on the Hope estimated weight, very good solid wheels! It’s the only wheels we buy now, 2 sets in the house and buying a third next week (and a set of Hoops with 5.1D, but they don’t count). I’ve tried a few dodgy 24 spoke wheels, never again.
Assuming a Deore HG50 cassette is on there, that’s about 430g for a start (going by the one I took off a Pitch Pro, brand new, this weekend). Lighter tubes can knock off half a pound too, depending on where you’re riding.
Might be worth taking your wheels off and weighing them, to see where the weight is hiding a bit better. Bet it’s all in the wheels, tyres, tubes, rotors, cassette as mentioned.
I’d be cautious of getting too caught up on weight though, unless you really feel it’s holding you back. It’s always quoted as it’s the most obvious quantitative way of comparing two bikes. Every bike I’ve battled to sub 24lbs I’ve absolutely hated.
