Should R-Sys's be illegal?

So I was just sitting around reading the UCI rules, and I came across this one (1.3.018):

On impact, no element of the wheel may become detached and be expelled outwards.
The rupture must not present any shattered or broken off elements, or any sharp or serrated
surfaces that could harm the user, other riders and/or third parties.
The rupture characteristics must not cause the hub to become separated from the rim in such a
way that the wheel becomes detached from the forks.

I did not know this. The spoke flying through the air in this famous photo http://www.flickr.com/photos/dcmphot...7603977693668/
would seem to indicate that R-sys are not compliant with this rule, no?

Mavic is a major sponsor. It'd never happen.

They should re-name the R-Sys the Mavic Detonator.

Bring back the Rev-X! The 8 bladed wheel of death! I loved those wheels. I wish I never sold them.

I have some of those that I was given. I'm scared to ride them, but man, they are fast when I do.

I always wondered what a squirrel dashing into one of those from the curb would look like after such an encounter. Those wheels were like Roadkill Processors. They scared me.

bit OT, but so is this forum. Are Rev-X's illegal in mass start races? If they are, does anyone actually care if I show up at a cat 4 race with them?

No. UCI only I think. I see them being used still.

I have had 2 fornicating birds fly right thru my front wheel and get tossed out dead and into a buddy who behind me in the paceline. I never went down. It was pretty nasty according to those behind me. This was during an MS150 ride some years ago. At the end of the day I was christened with a new Indian name "Johnny Kills 2 Birds."

I remember on a ride once a rabbit dashed thru my front wheel and managed to not get killed. Wierd.

I haven't seen a single Rev-X in any USAC races lately, so I figured the rule went for them too.

Yes. Don't remember the race though. It was right after they came out. Just pictures though, not in person.

If this is the same R-Sys we are talking about, then the SD rides them. Or atleast some of the riders do.

ive never heard of any trouble around the local circuit out here, we had a fuji sl and an orbea orca sold with em and both guys love the stiffness. One races, one doesnt. I think with enough force any wheel could get pretty F;d up

Yes, but the point is that the force from a crash does not send pieces of CF flying through the peloton when a normal wheel tacos. Even if a spoke does break they stay attached to the wheel. Keep in mind these are UCI rules, which USA Cycling only enforces some of unless you are in a championship event.

Wow, teams do ride them. Weird. The next time someone uses pro team product selection as an argument, I've got some return fire for them.

The wheel would have had to have been tested by the UCI and I am sure it passed. I have seen video of the testing and it has to do with a front end collision...I am not sure if they do anything with an object going into the spokes (like a pedal or whatever).

Make that two potentially life-threatening activities practiced by Saunier Duval...

I guess they needed the CERA to overcome the aerodynamic properties of the wheels.

I've ridden on them a few times now...nothing special. They are super stiff I'll give them that. They're respectable climbers, but you can feel the drag on the flats if you're use to something more aero. A good amount of effort is needed to spin them up as well. I would use them as a training wheels; but I'll take my Mike Garcia sourced Nio 19s when performance matters. Very dissapointing for what they're asking.

I am told Mavic isolated the detonation cause about six months ago and that the newer wheels have been redesigned. Allegedly a part that fastens the spoke to the hub was replaced. I don't think the newer ones are failing.

Can anyone else confirm or dispute this version?
