Wheels like the CLX 32s are right at home on a disc-equipped bike. The bulbous rim profile provides a wide footprint for a chunky road tyre – put a 28mm tyre on the CLX 32 and it will inflate closer to 30mm – and takes full advantage of the extra clearance typically offered by a disc-specific frame.
On top of that, you can forget any hearsay about disc brakes and weight, the CLX 32s will enliven any ride. With a shallow 32mm-deep rim, weight is key as far as these wheels are concerned and there’s little of it to hold you back.
As for aerodynamics, you’re better off looking further up the Roval range if cheating the wind is an absolute priority, with the CLX 50 and CLX 64 both on offer. Still, Roval have some paid attention to aerodynamic performance and say the CLX 32s are eight seconds faster over 40km than CLX 40s they replaced, despite being shallower (and lighter, for the record).
That’s thanks to the revamped rim profile, aero hub profile and bladed spokes. Specialized have their own wind tunnel and tested every influencing factor on aerodynamic performance during development of the wheels, and one nugget which emerged from that testing is the negligible impact of external nipples. Home mechanics rejoice!
