Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like :The Dirty Kanza". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

700x38 - is it enough?

Yes, you are correct! I actually thought about that, and simply forgot to add such a disclaimer to my post.

I do think you could go a little lower, though. Remember that you won't get pinchflats with a tubeless setup, so your only concern would be 'bottoming out' on the rim.

The one flat was the first year, and I was not yet tubeless. I pinch flatted bombing too fast down a descent, hit a rut.

I will attribute my good fortune to a good tire, extremely cautious (some might say cowardly) descending, and luck.

But seriously, it pays to be cautious on the descents on that race. That's where everyone flats or crashes.

That said, if I had the clearance I would have liked a slightly wider tire on this year's course--at least a 42.

That is a pretty burley high RR tire. Looking back would you change it out for something a bit more supple like say the new specialized pathfinder pro?

I never noticed it feeling slow and it's actually surprisingly fast on pavement for a file tread, I have to work a little harder to keep up with a group ride on road bikes but not as much as I would've thought.

I've never used the Pathfinder so I can't say. I've had such good luck with the Triggers that it's an "if it ain't broke" situation.

That said, there's a bazillion more gravel tire options than there were even 5 years ago and a lot of them are very good.

Next ones in going to try are Gravel Kings because I won a set at a race.

Next for me to try are Vittoria Terreno Drys. But, yeah, the Trigger Pro is a "don't fix what isn't broken" thing for me too.

I decided to move on from the Felt and ended up with a Kona Rove NRB. If I was a smaller guy, I think the 38mm tires would have been fine but the 650x47 tires on the Kona work way better for me. I havenít yet switched them over to tubeless but even running them at 32/35psi with tubes makes a huge difference in comfort and control. I figured if Iím going to do more of this type of riding, I might as well get what I want so I enjoy it.

A big advantage of 650b is big tires without toe rub.

My bike has no rub with road tires. When I mount the 38s, it's pretty significant. It's mostly just annoying, and it's caused a foot dab once or twice, overall, I live with it.

If I didn't have rim brakes, I would probably be riding 650b though.
