I’ve had the GCX 50 Light wheels on my Look Blade RS, which is very stiff, for 4 weeks now. I didn’t want anything too light in order to keep some inertia. I should mention I previously had Look’s entry-level wheels at 1600 grams. My bike is transformed. Comfort, performance. I’m doing long distances again because the bike has become easy to ride. I’m even shifting one or two teeth lower on my usual routes. My legs strain less. It’s astonishing. The build quality is top-notch! And above all, what value for money
