Who else is running “road” wheels off-road?

The spirit of Grav-lo-cross. No but seriously, cyclocross and gravel go here!

I recently switched a set of Roval CLX50 from my road bike to my gravel. Put 35mm Terra Speeds on them and have been enjoying how they feel on dirt climbs and how fast they are on tarmac descents.

Well the fun didn’t last long. On a smooth but steep gravel descent yesterday, I hit something in the dirt I didn’t see that pinch flatted both tires then I immediately hit another hard object and the impact felt directly on the rims.

The bike was not jolted in anyway because both hits really weren’t that big. But I felt the soft tires right away, got off the bike and sure enough, both rims were toast. I was able to put some air in them and limp home.

I know hitting two rocks in a row is unlucky but the impacts really weren’t that big so I’m still a bit surprised that both rims got busted. Would a set of all-road or gravel specific rims have survived? Hmm…

Probably 90% of the worlds cyclo cross riders are using road wheels off road.
I've run everything from GP4s, open pro, Dt Swiss clincher rims to some deep section Corima tubs'.

I'd just put it down to misfortune.

I smacked a rock with the front wheel with my gravel bike last week.
Pinched the sidewall of the front tyre right up near the rim bed.
Rim is fine.
Not entirely sure that would be the case were it carbon.
I want to get a better set of carbon gravel wheels, but will be careful where I ride them.
Some fairly rocky stuff around here.

tire looks shallow, not enough pressure for it maybe? would have probably destroyed road or gravel rim alike.

Well, the damage came from riding over a rock on the rims with zero pressure in the tires. That would have killed most rims.

Sounds like you were running tubes? Tubeless would most probably have prevented the damage as the don't lose air that quickly except if you put a huge cut in a sidewall

I've been running a set of Stans Comp 340's on my Gravel bike for years and not one single issue. I top up the Stan's every 3 to 6 months and all is fine. Running a SRAM RED 10 speed 11-25 cassette and Michelin Mud 2 on them.

I will keep repeating that over and over - use foam inserts!

And also hookless rims help a lot as well.

What is it about hookless rims that helps?

Not having a go, just wondering what the improvement is.
Stronger rims due to more material?

Correct, at least there is slight optimistic chance that hookless rim can survive bit more than hooked.

I used CLX32 for two seasons on gravel and they worked flawless. So you seems tou just have unluck with what you hit with your narrow tires.

What pressure are you running that tire at?

All carbon beaded rims have the bead machined into it, meaning it actually starts out looking like a hookless rim and carbon is machined away. Here is an easy way to see why hookless is stronger.
