You're right, sorry for the mistake.
I should have weigthed the original wheels with tyres, tubes, sprocket and disks and same with the new ones.
When mounting the new ones, I felt they are lighter and the guy who mounted the tyres and disks told me so.
I'd LOVE to know the weight difference of the bare wheels between the Kineo and stock.
I'm not keen on the 5" rear rim, I want to go narrower to 4.25" or 4" if I could get it. I love the tubeless right out of the box.
I've searched for other proper tubeless rim setups for the Sled and nothing comes up. I've contacted 2 wheel builders and it looks like I can get them built with Excel tubed type rims with SS spokes in various widths, but you have to tape the rims to go tubeless. The best price I found was from Dubya in SoCal but they won't tape them. Woody's in Colorado will build the wheels and tape the rims but they are 2x the price.
I've asked about getting the type of rims Yamaha and BMW use for tubeless but they appear to be proprietary.
I'm trying to figure out how much weight I'd save going with a 2.5" wide front and 4.25" wide rear rim which are more standard ADV rim sizes. I'd like a 4" wide but Excel doesn't make a 4" in 17", next step is 3.5".
The other aspect of the narrower rims is it gives the tires a more rounded profile vs the flatter profile of the wider rims.
