I recently purchased these and even though they came with 40mm Yksion Allroad tires installed I wanted to test out Mavic's UST tubeless. I removed one tire completely and reinstalled it. Seated within seconds using a simple floor pump. As soon as pressure got near 20 psi the tire popped into the beads. Easy as that. I deflated, added sealant, reinflated and it held air perfectly. Hubs are smooth, build quality seems strong, and although not the lightest wheels out there I dropped a full pound and a half off my gravel bike by replacing wheels, cassette and rotors.
My previous saddle was a stock one that came with my bike. It was good but over time it broke down. It also didn't have enough relief down the center of the saddle, hence this is why I chose the fabric line saddle. While the extreme line of relief might not be for everyone, but it worked out for me, no numbness despite purposely trying really hard. Based on previous assessments of my sit bones it was recommended that I used a 142 mm saddle, but those saddles turned out to be just too wide for my inner legs and consequently, they wore out my riding shorts. I recommend the saddle, but obviously, if you have the chance, try before you buy
