The rims are strong enough. I know of many riders you size riding them
without any problems or re-truing. There is something wrong with the
build and the person(s) truing them isn't taking care of the original
problem(s). Who built them? What spokes and hubs? You will want to get
the problem(s) resolved soon as the spokes are likely being fatigued by
the situation(s).

Unless you're riding in pot hole city, properly built, I suspect you'd never
need to true them for years.

CXP33 s are strong rims. Unless you are using 28 spokes (especially in the
rear), they should be strong enough with a good build and decent spokes.
You might want to stick with 36 spokes, especially in the rear and
especially if the roads you ride are bumpy.

Rims good; build bad.

rims are fine. Sounds like the build needs work.

I'm 170 lbs. Several years ago, I built a set of 3x 36 h CXP 33s and
have since used them for thousands of miles - including lightly loaded
credit card touring. Trued up the rear once.

I am your weight and have these on my heavy winter bike at the moment.
They have taken all I can throw at them, 1500 miles ish this year.
Unlike the Ma3's that were on it before but thats another (well
discussed) story.

CXP-33 are indeed appropriate for you if the spoke count isn't too low and the
build is a good one. Sounds like at least the second condition isn't true.

Probably poor build initially.

rims ok. can't judge the work from here. use a wider tire. 25 mm or 28.
you can also ask the LBS to wrap very thin iron wire around the spokes on
the point where the cross each other and to solder the wire and spokes
togheter with tin solder. Thus you create a series of extra triangles in the
wheel, making it stronger.

Please don't bother with the tie and solder approach. It just doesn't
accomplish any significant addtion in strength. William needs to focus
on the real problem of getting the spokes properly built and finished.
Wider tires may be a good idea, but they won't make up for poorly
built wheels.

I'm 230 lbs (on a good day). I had same kinds of problems with truing until
I got a guy to build me a good pair (yes, I know not doing it myself is
unmanly--I only ride sidesaddle). He used the CXP33 specifically; also used
14/15 (36 of them) spokes and DT Swiss Onyx hubs - they have been great and
true for 1 year 4K miles to far. I also use 25mm tires.

I've been riding a pair of CXP33s with 28 front and 32 rear for 4 years now,
with my weight varying between 185 and 205, over a variety of city streets
(Chicago) and bike paths. They have never needed truing in all that time
and mileage. Local shop built them up for me and they've been bombproof.

I'm not sure of the spokes make and the hubs
right now. I have actually forgotten. The
front just got retrued. It wasn't that bad.
The rear had a wobble that brought it very
close to the brake pad.

Newton is more than an hour from me with the
traffic and is PIA to show up there. To be
honest they seemed good but I bought a bike from
a shop that is much closer and convenient.
I'm going to check out the spokes issue as I can't
remember the name of the spokes.

I ride in Massachusetts. The highways such as 93
South of the Big Dig are worse for wear than the
local roads. Most roads aren't too bad. My street
was a horrendous mess of potholes and uneven pavement
until two days ago.

It's a simple thing, wheels come out of true because the spokes have
insufficient tension and loosen as you ride. A well tensioned wheel should
need little if any truing. If you learn to do this simple task yourself you'll
save much time and inconvenience, not to mention wear & tear on your wheels.

The time you waste going back and forth to your local shop, who
obviously doesn't know how to properly stress relieve and tension a
wheel, will more than make up for one trip to the reputable bike shop
who can probably fix the problem permanently. Like everyone else has
already said good rim, bad build.

Let me put it this way I will go find someone
in the area to give me an opinion. I was
wondering if the requirement of a little
truing would be necessary on a monthly
basis. However, the rear was way too
much last time.

Everybody thinks very highly of a person
just because of a website and I was not
very suitably impressed to justify taking
time off from work for him. My time is
spent elsewhere and 2 hours to go visit
is not going to appear. Thanks for the help
but recommending me to go there does little.

The same goes for most bicycle shops in
this area as I had previous visited a multitude
of them. I left with impressions of ill-informed
salesmen and questionable tech support to
be fraught with long travel times.

The story that I got from the bike shop
indicated that they need periodic truing,
but I didn't really buy it. So, what
I really like to know if there is a book
on building wheels. I will go take a look
for such a thing.

Just to clarify a question of mine.

How out of true would the MAVIC get during normal
riding? The people that mention that they do not
true their wheels, surely do not have perfectly
straight wheels?
