Subject: Looking for Good Replacement Road Rims
Hello,

I am anticipating an eventual rebuild of a pair of Real-Design Super
Sphere road wheels. The originals only lasted 5-6K miles before they
started cracking at the spoke holes. These were replaced under
warranty and now the new set has about 4K miles on them. If these are
like the first set I don't have too much time left on them. I would
like to line up replacement rims now.

The specs on the rims are as follows:

E.R.D. = 598.6mm
Drilling = 24 rear; 20 front
Manufacturer = Alex?

I would like to reuse the spokes as they are straight pull and should
be in good shape. This is why I need a replacement rim with the same
or very close E.R.D. Can anyone give me some suggestions for good rims
and/or places to look?

Have any of you ever heard of Alex as a rim manufacturer? Obviously I
would like to avoid these. At only 150 Lbs. I shouldn't be hard on a
set of wheels.

Thanks,

Steve

I've only used 36- and 48-hole Alex rims. That's high spoke count,
but it's still more pounds of me per spoke, to put it in
perspective.

Your first pair of rims may have been incorrectly heat-treated,
leading to brittleness. Or they may have been poorly lubricated on
assembly, resulting in galling at the rim-nipple interface.

Chalo and I are both big fans of Alex rims, but I do believe that both
of us run traditional spoke counts. Low spoke count wheels need
beefier rims, as there's no free lunch, so that is likely the problem.
You should be just fine relacing onto Velocity Aeroheads. Don't pull
the spokes, just electric tap the wheel to the new rim and transfer
the spokes one by one if you're lazy. This allows them to stay in
their same position and not get stressed in a different way...but I've
built a few wheels with used spokes that are fine. Have fun!

I just took a look at the Alex web site and they do indeed list a rim,
the R400, that apparently matches the originals to the ERD and number
of holes.

So maybe the combination of no eyelets and spoke count at the bottom
of the range are the real issues in the apparent lack of durability in
these wheels. I wonder if any other rim (velocity or otherwise) will
have the same issues for the same reasons?

As will 24h, don't think CXP-33 was ever 24h. 597mm erd for CXP-33..23
was 600 I think..I'd have to look up CXP-30..not made for a decade.

Well, you could use a Velocity Aerohead OC for the rear..similar ERD
and 24h available..

If you can't find a rim(Aerohead ERD is 602mm), you could always get
spokes to use for the front. OR use an Aerohead and use 16mm nipples..

You may gave gotten a defective wheelset the first time-- and as
landotter points out, that could have more to do with the build than
with the rims themselves. Alex Rims are made with stronger aluminum
alloy than most of the better-known rim manufacturers use. I can't
recommend another maker over Alex-- although I don't know anything
about the particular rim design in question.

Alex rims have lasted better for me, like for like, than any other
rims-- and I weigh more than twice what you do.

The old set of wheels was checked for spoke tension when they were
traded out. Tension was even and only slightly higher than the
manufacturer (Real-Design) spec. So it appears that they were properly
assembled.

Are your rims that you have had good luck with full spoke count or
reduced like mine?

Rain and not maintaining your bike. Clean the grit off the rim and out
of the brake pads and the rims will last a lot longer. You don't want
this to happen:

Sounds like the R400 (exact match on published ERD at least)... that
should be a good rim. The Aeroheads would be a good alternative.

Which eyelets were cracking... and are these 2.0/1.5mm or 2.0/1.8mm
spokes?

Is than an Alex R400?

These wheels have no eyelets under the nipples. Could this be part of
the problem?

What are these numbers refering to? Nipple and spoke diameter? I don't
have the bike at home to measure. It stays at work (under camera
surveilance) during the week for lunch time rides. I'll check these
two dimensions tomorrow.

I checked the spokes at work today. They are double-butted 1.8/2.0mm.

Velocity Arrowhead match, as do Mavic CXP33, 30 , and 23. But finding
them in 20-spoke versions will be hard.

How many kms for this to happen, does it make the wheel dangorous and

It depends on how much braking, the amount of riding in wet weather, and
how gritty the roads are.

Some rims have "wear markers" that indicate when the rim should be
replaced. The "rule of thumb" is to replace any rim with a wall less
than 0.5-mm thick.

Actually, I swear by Alex rims. Tough as nails. Problem is often that
they're used on lower end wheels and the wheel build is bad. Who knows
why yours cracked? I'd imagine because low spoke count wheels have
their issues. Don't fear normal spoke count Alex rims, that's for
sure.

Anyway, I believe Velocity Aeroheads will be a perfect ERD replacement
rim. make sure to get the OC Rear, as it really makes a sweet wheel.

The 7-1/2 year old Alex rims on one of my bikes are fine, except for
some wear on the brake track (which happens to all rims when used with
rim brakes).

i am on shimano r550's i had trouble with the bearings in the front at
2k, up to 4.5k now and no other issues, ok rim but not light or super
aero dynamic, good comuter rim, not good for speeds over 35ks/h as the
spoke cut too much wind, my next set will be more aero dynamic. so i
may need to look for cracks in a few 1000 k's.
I am of the half a mind that when that happens by another bike very
much the same, and wreck one for parts are needs, seems to be the
cheapest way (and saying that i am refering to the wheels).
eg. my bike $1.5k, the new wheels that i want cost $1.2k, better bike
WITH those rims only $1.8k best to get the bike for an extra $600 and
then i get a whole bike of spares as well.
