It’s all about the pinch flats isn’t it? Unladen rolling resistance is gonna be negligible and probably not noticeable by normal humans, on 26”/650b/700c the weight saving is what 40-50g per wheel max (depending on your tubes)
I certainly noticed zero difference between the tube and less setups on my 26” and if anything the bike felt less stable tubeless on the road. Anywho, I’m a lazy bugger and can’t be arsed to check/change the sealant regularly so went back to tubes.

Depends what you're riding I guess. I hate tubeless faff (although I've done enough installs now I know most of the tricks) but I'm using it for actual off-road. I've been running my tyres as low as 20psi over rocky stuff (when I rode XC in Oz I would run tubes at 60psi+). Bottomed out the front once on Sunday when I mistimed a rocky ditch. Couldn't see any damage, nothing went flat. Would've presumed that would be definite pinch flat on tubes but it's hard to say, really.
Tubes for road though - no fucking way am I dealing with sealant > 50psi.
hippy
Si, low pressure, no pinch
