Old Spinergy 4 blade carbon wheels
Scott Mann
carbon wheels. I thought it was a real nice gift at the time, but after
reading some random websites I'm starting to think twice about using them.
How concerned should I be about carbon spoke failure? I do value my health
and I'm big into self-preservation.
Not knowing what to do with them, I'm thinking about building a liquor
cabinet and bolting them on so I can wheel it from room to room.

Good call. They had some pretty public failures, and the failure mode is
catastrophic, unlike the more conventional spoked wheel design. Personally,
I wouldn't use them. Give them back to your "friend"! ;-)
Cheers,

They are likely fine!
I used them on the road and track; I have a pair on an old MTB;and I thought
highly enough of them to use them on my cross bike as well. I've never had
a problem, and I go over 190lbs. Look them over well, make sure there are
no delaminations. Then go ride. They are fairly bombproof, and the
failure rate is VERY overstated.

I have a friend that's a local Cat1 who's still racing on them and loves
them.
I weigh enough that I don't completely trust them, so I stay away.

You propably already read this one: http://home.interlynx.net/~pjdu/
I wouldn't use them for a frontwheel, when something happens to these wheels
(and apparently it does) the resulting injuries are much more serious than
with defects in spoked wheels.

Besides wiping with a rag to clean off dirt I replaced the bearings once.
The only failures I've had were one rear wheel cassette froze up after
30,000 miles and the rest were when other riders put their pedals in a
spoke. But after all the crashes with one to three spokes broke off the
wheel was still ridable, although not steady in corners. They were good
enough to hobble back to the finish line.
So use them.

It pretty much depends on which version ... the ones with the
stiffeners on the back sides of the spoke were better than the
original versions...that being said they are also old and the
stories are often true. I would be comfortable using them as
baisic training wheels, but would not want to sprint on them.
The lateral loads that would be inherent in a rolling liquor
cabinet would make these wheels inappropriate for that
application.

Even using them for training has its limitations. I tried riding them
on rollers once and the ride was simply too bouncy. I'm not exactly
sure why but it was probably related to the flimsy aspect of the
wheels.

Why would you want to put your liquor at risk like that?

I've ridden my Spinergy wheels on the rollers a time or two, also. It's a
strange ride ... but awesomely fast. Those blades really cut the air and my
average speed was significantly above what I usually have with my spoked
wheels. But yes ... as each spoke reaches the roller, there's a distinct
bump.

Scary !
A relatively innocuous crash in the pro peloton involving a bike with
Spinery wheels a few years back in the Tour of Germany was responsible
for almost severing the knee cap of one of the Worlds Top Pros -
Michele Bartoli. The details of the accident were apparenty hushed up
(with rumors of a damage limitation campaign by Spinery and reportedly
a very large compensation payout to Bartoli). The accident almost
ended Bartoli's career - thankfully he's now back to his best form
(he's this year's Tour of Lombardi winner).

Well, here is a source.

This has been kicked around here before endlessly. Let's just say, any
wheel can fail, but Spinergy wheels have the potential to fail
catastrophically and that can lead to a nasty crash. Spoked wheels can
certainly fail as well, but generally with less catastrophic results. I've
seen few, if any, spoked wheel failures that caused a crash and I've built
hundreds of wheels. If you inspect you Spinergy wheels regularly and limit
your risk of failure by making sure you have the right model, everything may
be fine. IMHO, I wouldn't use them. Others may decide the risk is ok, as
you believe it is. To each his own. Neither is right or wrong, just your
own personal assessment of the risk and what you believe is acceptable.
Cheers,
Scott..

...this is well known incident to anybody who follows professional
cycling. Well since this is a real horror story and Halloween is just
around the corner, on this occasion I will provide you with some more
information but if you want more you can do your own followup. Here's
the article...
------------------
You may have heard of Michele Bartoli the 1998 winner of the Cycling
World Cup well he had a little accident this year which ruined not
only his 1999 season read on..
Bartoli's Accident...A Real Horror Story For Halloween
We've all been waiting for Michele Bartoli to recover from his freak
accident of early June and return to cycling, no one is more ready to
ride than the former World's number one of Mapei. However, the most
recent word is that Bartoli will have to tap into reserves of patience
that he didn't know he possessed, after having the screws and hardware
removed from the knee on October 13th he experienced a strange
clicking from the injured joint the first time he went riding. Not
much was ever said about the accident that occurred during the Tour of
Germany, a crash that is threatening his career, but Cyclegossip has
heard some of the inside story and it's enough to make one queasy.
The papers reported that Bartoli had fallen heavily at slow speeds and
broken his knee cap, what in fact happened was that in crashing,
Michele's leg went into the wheel (the brand of which we must leave up
to your informed imaginations) of a team mate and it literally sliced
through his knee cap severing bone and tendons. When he went to stand
up his femur, no longer properly anchored to the knee, slid out
through the wound. Bartoli at that point almost fainted. This was
recounted to us by a team mate who was at his side during the episode.
It's been kept quiet by the team evidently to appease the maker of the
wheels. After the latest complications Bartoli went to the clinic of a
specialist in Como, Italy where Dr. Luigi Simonetto found that despite
the excellent work of the German surgeons there is a noticeable
thickening of the tendons severed in the accident which are preventing
the joint from functioning properly. His opinion is that Bartoli will
have to observe several more weeks of rest before resuming cycling.
The Italian champion, discouraged by the set back, said in the
Gazzetta dello Sport, "I'm not making any more plans or programs, I
don't want to set myself up for these disappointments, until my knee
is 100% healed I'm playing it safe. The desire to ride is enormous,
it's consuming me but I'm also getting tired of these frustrations. If
I can't come back for the first part of the season like I planned it
means that I'll be competitive for the second part, for the Tour and
the World's. I'm convinced that all this will pay off in the end, I'm
determined to make it back to my former level". He's trying to be
philosophical about his comeback, realizing that it makes no sense to
rush things when he has four or five good seasons left in which to
regain his former position as one of the best in the peloton.

Inspect them, how? Do you have X-ray vision?

I wouldn't touch them with a ten foot pole.

<snip Bartoli knee cutting incident story>
The _real_ interesting thing is that the edge on an equivalent era, bladed
spoke Mavic Cosmic was sharper than the Rev-X edge.
In fact, the UCI began its successful wheel ban efforts by investigating
this aspect of the Brand S product - it is also interesting to note that
there was no inclusion of this sharp-edge concern in the final
"safety-based" test protocol.
