Admittedly, coming from the Pirelli M45 - the RC45 should be faster. But, I didn't realize how much faster a "fast" tire is. So then the testing was on...Ramblers, Terreno Dry, M, and the Conti RK have all been "tested" on my varied gravel test loop. RC's beat them all handily. I will admit the Dry's felt amazing - a compliance I absolutely loved, but it definitely scrubbed speed. So it comes down to this - if you have a bike and geometry that allows you to "get away with" a speed tire, try the RC's. If you are tentative in the gnar/chunk or have a bike that is not all that stable, be safe and ride a grippier tire.
Great on any gravel condition,ride like silk on the road
