I've finished building the front wheel: Deore hub, CR18 rim, 32 spokes, PG, 2x, weight 800g without QR. I was surprised that it's 340g lighter than the rear wheel even with a heavier hub, rim construction and spoke construction.
No cassette, much smaller rim and tyres etc. Cassette alone is 300-400g of a rear wheel

It just dawned on me that most of the difference between the weight of the rear wheel and the front wheel is the freehub. Also a 622 mm rim is about 50% longer than a 406 mm rim, so I really should not have been surprised. I have yet to install a cassette.

I'm currently trying to clear an area inside the house so I can put the bike together. It's a bit difficult when much of the junk inside the house is not mine :roll:

You need to buy a gazebo and build it in the garden
If I had a baby elephant, I would put it on a recumbent trike so that it would become invisible.
