For an 80kg rider, is it possible to build a custom wheelset that outperforms Ksyrium SL wheels in every way for less money than a set of Ksyrium SLs on sale?
Looking for something with at least equivalent stiffness and weight for sprinting and hill climbing (better is better), but much improved aero.
I have had a good experience with my Ksyrium SLs for all round riding expect where strong wind comes into play (common complaint it seems!). I don't mind climbing, but growing up on a mtb, I love decending. The Ksyriums have scared the life out of me on what should be amazing fast decents when buffeted by strong crosswinds!
Feel free to suggest retail wheel sets that could surprise me.
For the hubs, the T11s from White Industries are going to be a hard option to beat. They are extremely durable, reasonably priced, and super easy to service. Oh and like the rims, these are made in the US.
For the spokes, I choose Cxrays from Sapim on most days. Light, durable, and relatively resistant to gouging.
Total weight would be 1436 grams in a 20/28 hole count. Oh and these would only be $740 shipped to your doorstep.
How big a step would it be to dip under 1400g for the wheelset? Would the drop in weight start to mean sacrifices in performance measures? Or only if I'm trying to keep it to a compatible price point?
Is that upgrade worth it? Well, it depends. When considering that we are on a Weight Weenies forum, most would say go for it. Personally, I would just deal with the extra hundred grams, and enjoy having a fatter wallet. That's just me though.

Ksyiums or say Campagnolo Shamals are system wheels and will spin and spin forever. All the constituent parts are perfectly matched. The other problem in my view with custom is warranty. Buy your Mavic or Campy wheels from a good local retailer or good online company and you won't have any warranty problems. If there are parts problems with handbuilt the builder will most likely have to send back constituent parts back to his surpplier with resultant delays.
uhm, ever had to replace a broken Ksyrium spoke?Good luck. Thats if the nipples havent corroded into the rim making replacement impossible. Mavic hubs arent the best either...
You can easily build a wheel thats lighter, cheaper, more servicable and with replacement parts significantly cheaper and more widely available these days than a Ksyrium SL.
Oh, and Mavic Ksyrium SL's are less aero than a pair of bog standard 32spoke low profile wheels(Proved in numerous tests) Those thick Zicral spokes are about as aerodynamic as a brick.
For a retail wheelset, consider Shimano Ultegra 6700 which I have seen for sale under $400, your shipping costs may negate the savings...

I realize I recommend heavier wheels that your 1400gm goal, from what i've seen most of the weight savings in a custom wheel is in the hubs. Most low profile clincher wheels have about the same weight rims and spokes.
Maybe the extra $400 can go to a really nice set of tubulars.

This just might be the reason I've lost confidence in my current set of Ksyrium SLs. Broke a spoke on the rear wheel and had to wait around a month before I found a shop with some in stock (others ordered spokes in for me, just to be delayed and delayed, then told they couldn't actually order until they met minimum order quantities from the suppliers - lots of mucking around). The LBS with the spokes in stock fitted the replacement and trued the wheel in a day. Got home to find that my LBS had twisted another spoke in truing the wheel and "this couldn't be helped because the nipples had corroded to the spoke." Of course then the sales pitch kicked in as I was then told it was time I upgrade!
I've built bikes for a long time, but my weakness is unfortunately I know nothing about building wheels - I'd love to have a crack one day.

What is the advantage of tubulars over clinchers?
Why stick to the dated Ksyrium concept in the first place?
Whilst the Campa efforts to attempt to copy and improve it where pretty successful (Eurus/Shamal) they still ended up with a similar set of engineering flaws inherent to the concept.
I.e. rather harsh riding wheels and way too wide aluminium spokes that are only aero at a certain degree of yaw.
There's a good reason why engineers won't combine carbon rims and aluminium spokes.....
Anyhow, I think you already received good suggestions yet I'm well aware that importing stuff from abroad is not that easy nor cheap being in OZ.
No good wheel builders locally then?

For one they'd allow to build a lighter wheel overall. Anything else would fall in the domain of what suits you best kind of set of compromises I guess.

Yep, $25 / spoke. Lucky it wasn't the red one!
My affections towards my SL's ended when finding that the non-bladed section of the spoke near the rim twists terribly when truing them - even when using the proper spoke clamp.
