    The only time I feel the Cotic is slower is on big downhills, due to being less aero, but that's probably more a function of the flared drops more than the tyres.

    I'm terrified riding down big hills on narrow tyres with caliper brakes. Is it actually slower or does it just feel slower? Because I reckon for 95% of people the improved traction and lessened road buzz will mean that you're faster with big tyres.

    Going down a hill wide tyres definitely have an aerodynamic impact making it slower.. But at a constant speed bigger tyres actually have a lower rolling resistance and can be faster.

    Yeah, I get that. I'm just wondering whether anyone has actually tried riding down a hill on a wide and narrow set of tyres and compared the difference. I reckon that unless you're going in a straight line on perfect tarmac, the fat tyres might have an edge.
