Hi all after my last few threads got another question about which one of these you would go for price being equal!.
Thanks and sorry for asking again.

Heard some pretty convincing talk that the additional aero benefits of the RS81 probably aren’t significant for the average rider, and I think the Ultegras are slightly lighter for not having the carbon fibre faring.

I had the RS81s though, lovely wheels. Be sure and learn how to use the bearing adjustment, it’s so easy to use it would be a shame not to keep the bearings adjusted perfectly.
