This is a cracking deal!
The Michelin Pro4 tyres are as good as anything I have ever ridden - wet grip is simply superb. Be careful when fitting them though, as they are a very tight fit on the Carbotechs - would be easy to pinch a tube.
The SRAM cassette works perfectly with any combination of SRAM/Shimano drivetrain - I'm running it with an Ultegra 53/39 up front, with a SRAM PC-1050 chain.
Shifting is quiet and precise and the 12-26 cassette gives plenty of gears for all terrain.
Schwalbe tubes do the job as expected.
Now for the wheels themselves......
so much better than expected. I've ridden over 500 miles on them so far, with no issues. Quality/finish is perfectly acceptable, and they roll along fine once up to speed.
An excellent commuting/winter training wheelset.
Considering that the tyres and cassette would cost around
