Wheel damage, how much is too much? Pics inside

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Wheel damage, how much is too much? Pics inside

On a group ride this morning when the person of front of me peeled off and didn’t tell me there was a crack in the road. Both wheels dropped in and scrapped my Roval cl50 wheels. Most of the scratches we surface other than the one in the pic. Finished the ride, 20 more miles, averaging 21mph with no issues. What are your thoughts on the wheel? I plan on pulling the tire and tube and running it by the shop. It looks like it caught the exterior of the wheel and didn’t damage the bead. It might just require a little epoxy to fix…hopefully.

I'd probably suggest taking the tire off to see how much that extends thru the rim material. This is one of those things that makes me question the 105% rule at least for most everyday riding.

Doesn’t appear that the damage went deep, just the exterior surface layer…but I’m going to have it checked out by a shop anyway.

This will be drowned out by the usual panic stricken carbon paranoid lunatics. It looks fine and is the least of your problems. Next time you go to a bike shop see if they have a cut end from a steerer tube for you to take. Go home and beat the crap out of it to show you how durable carbon actually is as well how progressive the failure occurs. I had the Airlines crush a carbon wheel on a flight then proceeded to ride approx 1,000 km across France without a issue.

You are aware it's there. Just do like I do with alloy rims or damage to any other part of my bike. Just look at it a little closer every other time you think about it. If you see bad stuff starting to happen, then you can figure out if it needs replacing sooner than later.

If you ride a the levels of a professional cyclist on mountain roads with steep descents and lots of switchbacks, then you might get some different advice. But for everyday average amateur riding it's not a problem to me.

If the damage doesn’t progress in the next few hundred miles, it likely will never progress.

Check with a mechanic, but it's probably fine. Maybe lightly sand it, clean it and add a very thin epoxy coat over the abrasions?

Everyone is an armchair expert so take the advice with a grain of salt. That said, it looks fairly superficial from the pics. I bet shop advice will hinge not on damage but rather whether they have replacement in stock to sell you. That’s my cynical side showing.

Keep using it but glue it down with epoxy. Make sure you get inside the joint and not just the outside. Keep an eye on it for a while. Replace those tires though! Poor things...

Doesn't Roval have some kind of "**** happens" coverage for the original buyer? Zipp certainly does, so I would expect others to have something, as well. Anywho, have the shop check it out and see if it needs to be replaced (but I suspect it's fine).

A lot of shops will just automatically say "replace it" because they don't want the potential liability that comes with saying "It'll be fine, ride it" and then having your lawyer contact them about that crash you had on a downhill segment when your wheel exploded.

+1 glue it up, otherwise it might grow.

Good thing it's not rim brake!

If you are well off enough to afford a new wheel why let this gnaw on the back of your mind when you fly down a mountain at 50 mph?

You can put a price on confidence with your equipment. What is yours?

I don't think that would help really. Only a materials specialist from the wheel manufacturer would have any clue on this kind of call. Even then it would probably be a bit of a guess.
I've worked with carbon parts in F1 motor sport for many years and learnt that it is actually very hard to predict failure in these situations. Looking at your pics, my gut feeling is that it would probably be just fine. But nobody can guarantee that!

Keep / Replace

My decision keep/replace would be most influenced by my age.
In my youth, I taco'ed a wheel sprinting, no helmet, bell rung, but walked home and thought nothing of it.
At 57, I'll do everything I possibly can to avoid a potential lengthy injury.
Even a small cut on a front tire can trigger me into a knee jerk replacement.

Luckily, even though I'm quite reasonably insured, my wife still cares enough not to question my safety related expenses.

Barry

PS: How do I describe yet another DI2 RD as a safety item... she's getting wise!
