>>116138135mm is plenty wide for rough pavement or groomed trails. Frankly too narrow for rough service roads, fire roads, or anything but the smoothest singletrack. Also sucks if it's rained recently and the ground is soft.
I've seen fire road days done on 35s, but I've also seen a lot of flats. 40-50mm is better.
When I see a "gravel" bike that doesn't fit the granddaddies of gravel tires - the WTB Nano 40c or Bruce Gordon RnR 43mm - I know that I'm looking at a CX bike or Endurance Road bike that the marketing team got ahold of.
>>1161402>UCI regulations don't stipulate tire clearance, afaik.They stipulate maximum tire width, and there's no reason to build in extra clearance that you don't need. True cyclocross race bikes have juuust enough room for a 33mm tire + a few extra mm of clearance.
>CX bikes practically never have the sloping compact geometry of the Domane, and they have the more uppright geometry of the Checkpoint.The slope of the top tube/length of the head tube is basically the least important thing. Look at the head tube angle, the fork rake, the BB drop, and the chainstay length. Those are the big things that determine how a bike will handle/feel.
