I've ridden plenty on 23mm on gravel - its fine in a straight line.

It depends on how much gravel and what percent of the ride it is - you'll get a wider tyre on the same rim as that - but what clearance is there ?

Personally I'd try it on 23 and see how it goes before spending.

  • I ride my 23c reasonably often on gravel, they are ok if you take it slowish (12-15mph) and the rocks aren't too big. The likes of ordinary cycle paths with a fine gravel surface are fine.

    tbh the biggest issue I have is not the tyres but that it gets the bike really filthy and takes a lot of cleaning.

    Wider tyres are better of course but it all depends on clearance, for the forks, brakes etc.

    It's more down to your speed and if possible getting in the right position before you hit the gravel.

    If frame clearance is generous you have the option for wider tyres but they are not compulsory. If you get a race frame, thin tyres are your only option. I suggest you hunt around for a frame with long drop calipers to accept 28 or even 32mm tyres.

    It depends on the thickness of the gravel too ...

    tbh I wouldn't want to routinely ride any distance on gravel with 23mm tyres - I'd prefer 30mm on the CX.
    Two reasons -

    1) Wider tyres flow over the uneven surface better - better for both grip and steerage
    2) the risk of pinch flats reduce with the wider tyres

    Loose gravel surfaces and bikes aren't a good combination on any tyre width.

    Yes, while road bikes are fine from time to time on gravel, I agree that if I were going on gravel on a daily basis that I might want something with wider tyres.
