^^ thanks for the tip on the Woodchippers. Since I'm also leaning to set up a vintage gravel bike ('72 Moto LeChampion), I want to keep components near period. 99% of the bike is original but for an unknown / non-branded 285gm drop bar. As such, now considering to tweak bend the flare to my spec..

Tires-

Pete's commentary on the tire separation is interesting. Perhaps are they are subpar quality or made with lack of glue but I can see where low PSI causes problems. Curious if hot ambient temps has played into it. I've had cheap Hutchinsons melt flat spots while parked on the hottest tarmac.

Experimenting with tire pressures probably the most drastic changes one could make with a bike. More so than tire selection, etc. I've gambled running low PSI in the rough for 32c rubber. I like the ride and hook-up in really loose surface but have pinched flatted (rear's only) when just riding over minor rocks on a single track trails. There's always that should have 'bunny hopped' moment and it happens so fast. If you have the volume (wide / tall rubber) surely try a lower psi.

I'll have to look again at one pair of clinchers I have (thinking they're Vredestein 34c) with a very tall profile but knobby that's been working excellent in some really rough singletrack. For the vintage gravel project, definitely not keen on using a knobby. For these, usually 70-75 psi front / 85-90 rear.

This is one reason I'm looking to go tubular with a sealant for the vintage rider.

The other option is clincher with a tubeless conversion. There's not that much to it. Can do the ghetto thing, wrap the rims with electrical tape and just get the valve w/seal set. A quick high blast using an air compressor will seat the tire. Deflate and fill with sealant. Inflate again to a low pressure.

Lastly- I really like the Tufo road tubular / clincher for clincher rims. Hope someday they offer a CX version.
