Narrow gravel or cyclocross tyres (30-33mm) on road bike

[peevee]

I'm looking to do a bit of light gravel riding on my Specialized Roubaix (2020 model) but the frame will only allow tyres up to 32-33mm which I believe seems to be the cyclocross standard. From what I've seen online, the Vittoria T10 Hardpack CX Endurance (32mm) seems to be an option for the rear and a Vittoria T30 Fine Loose CX Endurance (31mm) for the front. Anyone tried similar tyres on a road bike for light gravel riding or have any ideas of other options and where to buy them? TIA

Not sure where you’re based but I’ve seen them at Trailwolf, just not that size. Them or any other LBS would probably have to order in for you.

I’ve been running Challenge Getaway for a bit now and have been mightily impressed. 
Maybe there’s something there that could work https://www.dinao.store/brand/challenge/

Tufo and Mitas/Rubena could also be another option.

Specialized also do some proper CX/gravel tyres.

Continental, not sure about their local options but there may still be stock of their 33mm tyres.
