There’s a whole scale of gravel bikes though – bikes taking up to 35c tyres to those taking 50c. Many around the 35c-40c mark, depending on whether there a front mech
And the geometry differs as well. It can change the handling dynamic of the bike on the road quite a bit.
Some of the bikes with much bigger clearances have lower BBs and slacker head angles. They can feel a bit sluggish and/or cumbersome for regular road riding. I’m happy to make a compromise on the road handling by adding a long/low stem to get my normal position. But if I didn’t want the ability to swap to a shorter reach for off-roading, then I’d want to bake that in to the frame to sharpen up the handling a bit. I’d also go for something like a 72? head angle rather than the 70.5? of the Tripster.
And I’d want to be running some nice 28/30mm tyres. Something like Challenge Strada Bianca with latex tubes, or Schwalbe Pro One tubeless.
