I've got a 2015 Cannondale Synapse 5 Disc 105 (Aluminum) and I'm looking at a second set of wheels. My main interest is in my health probably #1 , but as far as racing - only centuries, gran fondos, etc. (I already asked this in the long distance forum and it didn't go very well). I do enjoy and am motivated by Strava and I've racked up like 4 top 10 placements in the last couple weeks on segments that I cross - which I really like to see.

I really can't see myself making a commitment to expensive disc wheels and not knowing if my next bike if I ever get one will be able to use them. There aren't a lot of disc wheel sets out there right now it seems to me. Which maybe impacts the pricing - they are notably more expensive than their rim brake counterparts and that might be justifiable in the need for a more robust build. IDK.

I don't think my bike is ever going to super light - it could be much lighter I'm sure (riding weight with all the junk I carry is around 25lbs currently). I'm not really interested in carbon wheels. Lighter and faster would be nice, but not for as much money as my bike cost me.

I also recently purchased an indoor trainer and the second set will be handy for that. My current wheels have been popping spokes and they might be done period (some really harsh trails here).

I'm leaning toward a set of the Mavic Aksium Pro Discs. They are fairly cheap, but seem to be fairly well regarded at least for being robust. The Ksyrium Discs go for like $1,250 and that seems a bit steep to me. Any input or other suggestions? The Aksiums are on sale today for like $270 with shipping. I'm ready to just buy them and be done with this.
