As far as weights:
- 147g tube (28-38C)
+ 5g tubeless valve stem (48mm)
+ 90g OS endurance (90mL)
I didn't weigh the factory rim strap vs. WTB tape, I'll call it a wash. I also installed a CG-R "cobble gobbler" 350 mm carbon seat post... but, tire pressure and tubeless made a bigger difference to comfort. I would put in order: tire pressure > tubeless > carbon seat post
Exceptions might be sprung seat post like the Redshift, Kinekt or Canyon VCLS 2.0.
My experience is similar. I have a redshift shockstop seatpost. It made a substantial difference when I was running 50PSI+ in 42mm tires with tubes. I could see how it would be a game changer to someone running higher pressure 32mm tires on gravel or roads. Now that I am running tubeless at pressures in the 30s, even with slightly smaller 38mm tires, there is no real difference in general comfort using the Redshift, but it does give me the ability to stay seated over larger bumps. To anyone considering a suspension post, I would definitely redommend larger tubeless tires and lower pressure as a better investment for a first step, and the shockstop post if you still feel the need after that.
