Help deciding on a wheel - carbon disc tubeless

I have a Cannondale Supersix Evo disc with factory Mavic Aksium wheels and I'm looking to upgrade. I'm getting a set of Schwalbe Pro One 28 mm tires and I'm currently shopping for wheels. I was wondering if anyone has experience with any of the following:

Acros Road Disc Carbon's
Easton EC 90 SL Disc
Bontrager Aeolus Pro 3
Renold Assault
Mavic Ksyrium Pro UST WTS Disc

Any sense of improved performance over less expensive, non-carbon wheels would be appreciated as well, such as:

DT Swiss ER 1600 Spline 32 mm
Mavic Ksyrium Pro UST WTS Disc

Appreciate your help.

Let me put in a good word for Boyd Johnson's 44mm disc brake wheels (I went with the White Industries CLD hubs option). I've been running them tubeless with 25mm Schwalbe Pro 1 tyres and Orange Sealant.

These wheels have performed flawlessly and performance is certainly a cut above the DT Swiss R24 Spline stock wheels which came with my BMC RoadMachine 02.

I weigh 75kg and have been running the Boyd 44mm / Schwalbe Pro 1 wheels with ~70PSI front and 80PSI rear. At some stage I'm going to try them with 28mm Schwalbe Pro 1s and lower pressure simply because I like trying new things.

Two things I have thought about a bit:

1) You might find that running 25mm tyres tubeless allows you to get away with a lower pressure that is so comfortable (whilst retaining good rolling resistance) that you really don't need to go as wide as 28mm... --> I'm planning to try 28mm for the express reason of testing this theory out.

2) If you deeply care about aero performance, then there are virtually no mid to deep section carbon rims having sufficient internal and external width to blend nicely with a 28mm tyre profile. Perhaps only the Enve SES 4.5 AR? Are there others?

I have Assault SLGs, found them for about $1200. Love 'em. As far as comparing them to other wheelsets... yeah, they feel approximately 27% more lively in sprints and 32% more confidence-inspiring during the twisty bits. :innocent:

Okay, so maybe not, but the point is that you're not going to get any meaningful second-hand comparison; you'll just have to give 'em a spin yourself. I'll say this, though - would I buy them again if I wrecked? Yes, I would.

Oh, and FWIW, I ran these with some 30mm Schwalbe S-One (now G-One Speed) - awesome ride. For me, any new bike consideration will have to factor in whether or not the frame will accommodate them.

Just a word about the Mavics: I'm looking for a second set of wheels as well, and reached out to mavic on tire compatibility for their UST rims. They said that while other brands may work, they don't guarantee compatibility or a proper seat of the tire. At this point I'd steer clear of UST rims simply because your tire choices are extremely limited.

Are you looking for rims that are gravel capable? If not, look at the DT Swiss PRC 1400 sets, as well. Nice looking rims for the road.
