wheel

William H. O'Ha

So,

I had thought that I had my wheels straight and no more
problems. I broke a spoke on the non drive side in the rear.
I'm riding the Mavic CXP33 with american classic hubs.

I believe that I broke the spoke while riding the bikeway
from Forest Hills to downtown Boston, MA. This route
contains some bumps, but it is not that bad.

Did I break the spoke while leaning to the left or the right
somewhere? I was wondering if the wheel is flexing up and
down too much.

I am still around 200#. I'm thinking of going for Velocity
Deep Vs with 105 hubs and heavy db spokes or the Velomax
orion. I haven't trued the CXP-33's except for once since my
never ending truing experience.

thanks bill

Well, that is the most common place to break a spoke "while just riding along"
What brand and model spoke?
Who built them for you?
What tension on the drive side?
Where on the spoke did it break?
Were they tension balanced and stress relieved?
I think you choice of rim is fine for your weight.
I would just replace the spoke, spoke align, check tension all around, true the wheel, remove any wind-up, tension balance, stress relieve, & ride on.
The wheel is not flexing up and down too much unless the spokes are under-tensioned.

If you are breaking spokes, it is likely because they were
not properly stress-relieved at the time that the wheels
were built. This leads to fatigue failure. Rebuiding with
different hubs, rims, or spokes won't make any difference
unless the wheel is built properly.

Wheel is sick, either from a poor, too low tension, not
stress relieved build or the rim is 'bent' and not round,
causing a spot with low tension. CXP-33, with dbl butted
spokles, and a GOOD build should be fine for you.

Not from turning or flexing or anything like that.

Stay away from velomax wheels.

Well,

you are the first person to say to me that Velomax would not
be good. I had about enough with this wheelset. I haven
taken it around to many different places now. I think that
the rear has a little spot after the spoke broke too. The
fellow could not even it all the way.

These are supposed to be tensioned properly per the last
person to look at them. I think that the straight gauge
spokes at the 28 count has not worked well. I don't know how
good the American classic hubs are either.

The velomax was sounding interesting with the supposedly
stronger hub to spoke connection. Everyone around here is
swearing by the their strength.

I have not put up many miles on these wheels and I
have grown very tired of truing. I think that the rear
has had it.

I am already conceding the wheel was not built properly. It
had to be fixed. I went and had it trued properly. It had
stay in true for several weeks.

I had a flat today going uphill while off the saddle. I
heard the whoosh and immediately came to a stop on the side
of the road. The rim is now horrible out of true. I am
really interested in the Velocity semi aero rims with a 32
spoke count for approx $200. Any questions about quality or
is the exchange rate the factor in the lower price range?

Let me get this straight, you had a "flat", then you heard a
"whoosh", and now your rim is "horribly out of true"?!

One suggestion, instead of spending $200 for questionable
rims (you're really want to spend TWO HUNDRED DOLLARS for
a pair of rim?!#$), why not just have a LBS true up your
wheels. Probably should not cost more than what $5-15
each, max!

Better yet, maybe buy The Bicycle Wheel (about $25) and
learn how to true up yourself. $200 for a pair of "semi aero
rims" is not a good deal....

I was thinking about building it myself actually. I prop
could do it better than most of people around my local area.

I went into a local bike store that everyone on the 'net
talks about. I was not impressed with their attitude or the
prices. I would not let them build me a wheel. They would
end up charging me thousands for a poor job. They would
decide what I wanted and how much I should spend. I am more
interested in hearing about quality of Velocity. If I use
ultegras for the hub would it really make a difference?

I'm not going to buy dura ace.

I have am classic right now.

I have the book. I have read it. I have properly tensioned
my wheels with someone else. I had them working good for
about two weeks. I am not in the mood to true the wheels
two or three times a week. They continued to go untrue
very often.

On Tuesday I had the rim about 1 inch out from the rest of
wheel at a certain spot. The wheel could not be trued that
well either after this one.

I can true the wheel myself. However, I am looking for a
wheel that will last me longer and not break several spokes
when I am 30 miles away from home.

A properly tensioned wheel will not go out of true every
two weeks.

Your rim is likely bent, and will be unstable because
adjusting the spoke tension to keep it true results in some
spokes being too loose.

The real test is to observe the rim without any spokes in
it. (I know, that is pretty much the same work as building a
wheel.) A good rim will lie flat on a flat surface. If the
rim will not lie flat, it's best to replace it, and others
have told you, that is relatively inexpensive.

If you want to do this on the cheap, or if you have some
emotional reason to keep it, it may be effective to persuade
the rim to be flat by some judicious bending.
