13, I think, maybe 14. Plus 7 on the other number. Not enough for a win though.

A buddy of mine won a set last year. He used them once, and he didn't seem impressed. The second time he went to use them, he wasn't paying attention when putting them on and let them slam together. Apparently that is a No-No, and they broke.
They are your brakes. Do you really want to go cheap and risk them not working when you need them most?
At this point, if I were to buy a new bike, I'd probably go with one with discs. I am convinced that in a few years, it will be nearly impossible to find a frameset for rim brakes - just look how hard it has gotten in cross in just two years. It's not necessarily the direction I want to go, but it really seems to me that is the way the industry is going.

Anybody know of somebody who beta tested the new stages firmware? Anybody hear anything about it having problems or being unstable?

I just bought Race Dots, haven't tried them out yet. I have a fear of going down and a pin going into my skin, cutting into my intestines, and having to wear a pee bag like that dude on The Wire.

3M 77 combined with GooGone GEL (not their Heavy Duty stuff). It helps to just really wrinkle the number, then spread it out and it is barely noticeable.
Get someone to rub it on.
Sat number (good/typical ink)
Sunday Number. I stopped wrinkling as the number ink was coming off - inc. on the jersey. Starter ref was concerned about reading it and chief ref had no issue.
3M 77 spray - let dry till tacky (5 min)
Spray Gel on underside and wash

New / old topic. My son has pulled wheel out 4X this year. 2X it was a big deal - VOS RR and yesterday. It always happened in big power. 1st time - thought it was a loose skewer. 2nd time VOS RR - thought it was a loose skewer. 3rd time was VOS crit and I clamped that thing on tight and it came loose in the sprint. We were using the KCNC Ti skewers. Last year he had no issues. He had not really sprinted since VOS other than in training when these wheels are not on.
So Venge has steel plates on dropouts. His prior bike was just carbon dropouts.
Really smooth hub face - hard anodized alloy.
And - lots of chain lube and not so tight skewer.
A beefy Campy serrated skewer may also help.

Lock washers?

I guess I did not properly report we gave up those skewers for steel shaft. But that was after the 3rd time. The first two I blamed him for putting them on too loosely - which he does do. We went with steel yesterday but caps were not heavily serrated. Yesterday he did mount his own wheels and they were not that tight, but never had any issues before this year. The new variable is the frame - which he loves, but I'm looking at dropout angle, steel plates etc. Sure, a standard wheel, with standard hubs would likely be a fix - but how fun is that?

Steel, but still the lightweight skewers with undersized clamping surface? Or normal skewers. I can send you a set of DA skewers if you want, those are the clampiest of the clampy, but they might cost you all of 100g.

I had my rear wheel pop out recently in a group ride sprint (on a Venge). Scared me quite a bit and I lost the sprint. Since then I have been cranking down the rear skewer (pretty basic steel skewer) a bit more and it has been fine when sprinting.

honestly....how big is your kid and how much power is he putting out? skewers work for tons of people out there--even the WW one.
INTERNAL cam designs (shimano and campy) are the most secure, but having a wheel fall off is (a) super rare and (b) terrible...esp for everyone else around. it is like rolling a tubular.
you've had to add weight to your kid's bike. just put on the proper skewers.
(i have never had a problem with zipp, shimano, or even the weeniest of weight-weenie skewers....even for MTB, but obviously this kid's mileage varies. i don't want to read a thread about him busting up his face.)
Edited to correct brain fart -- meant INTERNAL cams. (Thanks @globecanvas.)

I am trying to figure it out. So for now - serrated washers.
As for adding weight - only UCI races. And that's a bit depressing as they don't check.

Correct. I understand I could have just gone big brand components. But there is a transition going from fun weight weenie stuff used with an 80# rider to real racing. These are fabulous wheels - except when married to this frame. I'd switch the frame and keep the wheels if we weren't on a team. It is the combo that seems to be the issue. I thought it was my son not tightening his own skewers, then I thought it was the skewers. Its also the frame and the hubs. Its all the above.

What were your hubs and skewers? Also were the hub axil faces serrated and of what material?
These hard steel dropout faces that Specialized is putting on the Venge are part of the issue.

Hubs are White Industries. Skewers are whatever basic ones RaceRim uses. I'll check on the hubs in the morning to see if they're serrated.

I have sprinted my rear wheel out four times on my Foil. All four times were with the same wheel/skewer. Zipp 303 and Zipp Skewer. It ended one race entirely, cost me a second one by dropping me from the field with 40 headwind miles to go, and the other two times were during warmups. There is a permanent scrape on the chainstay from the wheel. No amount of hand-tightening solved the issue.
This Mavic skewer fixed the problem. Completely.
