Upgrade SCS disc wheels

plymouthsteve

Hi.. I've just become the proud owner of a new 2016 Specialized Roubaix disc.
the bike is great but the wheels are screaming out for an upgrade.
The bike has a very up go date, but very rare SCS (short chain stay) wheel type and the only off the shelf wheelset I can find is some carbon Rovals which, at £1500 is about three times my budget, and almost as much as I paid for the bike.
I've had mavic ksyrium in the past on rim brakes and loved them, but it seems that the current ksyrium disc doesn't come in an SCS compatible version.
Does anyone know of any plans for more compatability, or whether the current mavic ksyrium can get an adapter or something that might offer a solution?
Thanks

How are the wheels different to any other disc wheels? They must be a standard size or buying tyres would be an issue. Are the hubs different? I doubt it, they would be either QR or bolt through.

With a bit of Googling it appears that the SCS difference realtes to the hub design so that they optimise the chainline on bikes with short chainstays. They are also thru-axle rather than QR.

Other than that they are standard 700C wheels. Can't imagine that any other disc wheelset would cause major chainline issues - must be only a few millimeters in it at most. I'm sure also that you could use QR fixed wheels if you want to avoid the thru-axle type.

Ah, ok, not sure how much trouble that would cause. Thru-axle are not a problem, lots of hubs will do both. I'd probably find a local wheel builder and ask if they have a standard disc wheel you can try in the frame to see if it works. If it only limits things at extremes of big-big or small-small I wouldn't worry and get a set of handbuilts.
