David Snaith : my 2013 R3 with the new 45mm U-shaped wheels.
I have ridden about 200km on them now and they have been amazing! Thank you so much! The wheels were perfectly true right out of the box. The bike is now lighter and stiffer and accelerates much faster. The aerodynamics of the wheels, at least subjectively, feel like it has raised my top speed by a few km/h. Even in gusty crosswinds, the bike feels stable and predictable. And as a bonus, the ride is noticeably smoother and more comfortable.
I am using 23mm Vittoria Rubino Pro tyres and SwissStop Black Prince pads with about 1mm toe-in. There is plenty of clearance for the tyres and so far everything seems to be working perfectly.
