Quoted message said:While I no longer race I still ride each day. For many
years I rode on 36 spoke rear wheels. I am 6'4 225 and in
my race days I was only 190. Even at 190 32 spoke rear
wheels were a disaster. Going to 36 spoke wheels helped
but I still had to work on the wheels every 2 or 3 weeks.
When I made the move to a new Campy 9 speed wheel with 36
spokes and mavic open pro rim, it went out on the first
hard hit it took.
Huh. I am about your size, racing weight without much fat
was about 195 and currently am about 215, with more fat than
I want. As I get older, it doesn't come off as easily as it
did! I raced on 32 spoke wheels for 10 years and rarely if
ever had trouble with them being unreliable- as in going out
of true from just riding or from hitting bumps. Never had
much trouble with spoke breakage except in one wheel built
with Asahi spokes.
Basically, I have to think that your wheels have had some
problems with build quality. 36 hole Campy 9 speed with an
Open Pro rim ought to be strong and durable, at least until
it cracks (see the many threads on anodized rims. This ought
to start another one now). Either your spokes have a lot of
residual twist in them from tensioning or they are quite
undertensioned overall, is my hunch.

Lenard Zinn of Colorado (a very well known racer and bike
builder who is a 6'6) he recomended going with the mavic
ksyrium elite. After 1500 miles I have not touched them
and they are as true as when I got them. I like many have
read the endless posts about designer wheels. Many seem
to say that they are a waste of money but, from my first
experience with the ksyrium elite I am sold. I have never
had any trouble with any kind of front wheel, only the
rear which I am sure is due to the dish.
Dish is a contributor as it makes for a weaker wheel, and
unfortunately it is also the wheel that carries more than
half of the load (somewhere around 55-60% in most cases).
However, many heavy riders have used highly dished wheels
with good results provided the wheels are properly built:
evenly tensioned, highly tensioned, stress relieved and
built with proper spoke wrench use so that the spokes are
not twisted.

have had. I posted a similar questions a while back. The
response was a LOUD get a good wheel builder to make you a
quality 36 spoke rear wheel...and to stay away from
"wheels in a box." I had three hand built wheels. They
lasted 316 miles, 412 miles, and 453 miles. I will be glad
to give the three names of the LBS that built the wheels
if you contact me directly.
Hmm, people who live in your area should be warned about
the inept wheel building this LBS is providing. Good grief,
barring accidents or unusual braking wear on the sidewalls,
a rear wheel ought to last at least 10,000 miles and more
like 50,000 miles before anything needs to be replaced
(except maybe bearings). I hope you got your money back!
Shucks, my 32 spoke Campy 9sp with MA2s have been in
service for at least 10,000 miles and are showing no
problems at all.
