Best OTP CX Wheels (for me)?

It's not for a particularly fancy bike which is why i'm going for complete wheels, otherwise i'd probably build my own. No plans for racing them either, but occasional muddy rides on weekends etc.

Just get some Askiums or RS10s then. Any otp wheelset will do unless you weigh 30 tonnes and are utterly hamfisted when it comes to bike handling.

Spend the £200 change on something worthwhile.

If you really want to spend the £300 strada do a velocity a23 build for just shy of your budget.
