A customer brought in a 9000 tubeless wheel for service.
Actually, it's not just the wheel itself — I have the customer's cyclocross bike in for a pre-season overhaul,
and this is the rear wheel.
↑The rim's bead hook is dented from buckling.
That's why the brake shoe contact marks are interrupted.
↑It's dented quite a bit like this.
The customer remembers how it happened.
I marked it since it was hard to see.
It came out pretty nicely.
By the way, this wheel is a tubeless rim, and the customer uses it with tubeless tires.
More than 10 days passed between when I received the bike and when I straightened the rim,
but during that entire time with the bent bead hook,
there was very little air loss (←no sealant)
which suggests that the tire's performance is actually more important than the rim's bead hook
when it comes to air retention.
Of course, the tubeless valve is important too.
I won't write down which tire manufacturer makes that excellent tire
because it would start to smell like shilling.
All fixed.
Oops, I accidentally shot the tire in that one.
Schwalbe CX Tubeless.
The tread pattern is (→here)
As I noted in that post, cyclocross races are supposed to run below 2 bar in practice,
but the fact that this tire is rated for 3-5 bar is due to corporate politics.
The way they say "self-responsibility" feels a bit dodgy too,
but you have to understand why they can't just say "1.6 bar is OK!"
Bonus
The front wheel was Schwalbe CX Mud Tubeless.
Here's the tread pattern. The right side of the image is the direction of travel.
If you're looking at WO cyclocross tires,
Challenge is the best for rolling efficiency, ride comfort, and tread pattern variety.
But if you're going tubeless, I'd personally recommend IRC's Schwalbe CX as the top pick.
