I'm thinking to upgrade the wheels on my Emonda SL6. Current wheels is Aeolus Elite 35.
I'm curious if anyone has the experience of riding the two or pointing me to a good review.
Typically my riding involves climbing, and I'm not a racer and don't care much about aero.
On paper, Alpinist is lighter than Aeolus, but which one is stiffer?
I don't mind mixing up the brand, and that's okay if people have opinion on my bike.

The Aeolus RSL 37 is deeper, wider and officially tubeless compatible. Easy choice for me.

They now have a even wider version (25mm internal, 31mm external). Very appealing!!TobinHatesYou wrote: ↑Sat Jun 12, 2021 6:57 amThe Aeolus RSL 37 is deeper, wider and officially tubeless compatible. Easy choice for me.
But roval has the Terra clx. Best lightweight offer they have.

Just ran the RSL37 with tubes during an Haute Route event and they were absolutely fantastic. I was running 28c front, 30c rear Conti 5k, and the wheels felt super fast uphill, fast enough on the flat bits and were stable on 70+kph descending.
I never rode the Alpinist but there isn't much more I could want from a climbing wheel.

Both the Rovals and Aeolus are top end wheels. That said, despite the increased weight, I would opt for the Bontragers. The Alpinist are optimized for climbing, while the Bontragers are more a general wheelset.
A note on the bontragers: The RSL 37 is only 2w slower than the RSL 51, which is a fair trade for the stability when going down hill. Going uphill aero doesn’t matter. Flat landers should go with the 51s. That said, unless you have frame considerations, the wider RSL 37V (different than the RSL 37) with 28s or 28F/32R tires makes more sense to me. Unike Zipp or Enve, the hooked RSL 37V has general tire security and wide internal width. I suspect the next generation Rovals will look like the RSL 37V.

I'd say current gen is pretty on par with RSL37. Weight and aero drag should be about the same. Might just be about which tires you want.

the new Shimano C36 Dura-Ace wheels are not good, the hub still use the old school, I sugget for ride more faster is using carbon spokes
check this comparison table chart
you can see the good perfomance in climb and aero is SLR 2018, Yoeleo or zipp 404 and of course Farsports and Hyper.

I have the RSL's now for a couple of month and I am very satisfied. Saying that, I have no real comparison as these are my first carbon wheels (used alloy HED Belgium+ before). However all I can say is that they roll just fantastic, engagement is breat, they climb very well and found them very good on the flats as well. Broke pretty much all of my PR's in last few months and they are just so smooth. Again, I can't compare it against anything else similar but I am certainly very happy with them.
