• Is it even a compromise? The speed-vs-comfort thing is always invoked, but is there actual data against Heine's thing? Or is it just habit and ride-what-you-have (which is fine)?

    Heine's tests aren't perfect, but they seem pretty good? I only saw the figures available on the website, but two limitations come to mind: there might be a ceiling effect to their tyres, i.e., all compass tyres are just really good and it doesn't matter which you ride, whereas a gravelking would perform differently between sizes. Or, the effect size of interest was not determined; there may be a non-trivial difference between tyre sizes, but the tests aren't sensitive enough.

  • Sorry I was being a little factitious, I don't really know much about Jan other than his love of wide tyres (which i share).

    I personally love Sawtooths in 42 for my bike, which is 85 road 15 UK 'gravel'.

    Everytime I'm on the road though and I hit potholes and lumps and cracks etc, I'm pretty glad I'm not on anything thinner.

    See loads of roadies in the south downs near me still on 23s and it makes me shudder!

    I think this makes it for me too, although personal preferences are totally fine. E.g., a friend that's been audaxing every weekend for years now swears by his 23c. My biggest tour was on the same size, but now that I switched to 42, even 30 is a pain in the ass.

    Imagine how much it makes them shudder...
