Ritchey OCR rims

Has anyone used Ritchey's Aero OCR Pro rims? Any opinions you'd share?

They really do make building a rear wheel easier by minimizing the dishing (helping minimize the
difference between bracing angles on the right and left side).

Quoted message said:

I'm tempted to try one rather than rebuild a wheel with an Open Pro--the Ritchey is significantly
cheaper, lighter, and has a better (deeper) profile.

That doesn't happen often, does it (lighter, faster, cheaper, choose any THREE)?

At the same time, how is building with the "off center" rim? Is it really stronger and easier
to build?

It really is easier to build and should be stronger (due to the better bracing angle for the right
(drive side) spokes.

In my experience, Ritchey products are usually good values: good designs, good performance, very
reasonable prices. Their stuff isn't fancy or highly hyped, but it works well. The only problem area
is their pedals, which are apparently made by Wellgo and are significantly inferior to similar
Shimano pedals.

I've heard Ritchey makes wheels with zero dish, using OCR rims, and their own special hubs. Is
this true?

Wouldn't the flanges have to be closer together to do this? How does that affect wheel strength,
compared to having wider flange spacing, but asymmetric tension?

Just curious - in what did you find the pedals lacking? They seem nice to
me. Those have an oilite bearing like an electric motor and feel very smooth when new compared to
low-end ball and cone models. Unusual but I wouldn't say "inferior". Did I miss something?

I've heard alot of complaints about the click-in mechanism jamming or breaking. They also don't
float as well or hold as well as the Shimano pedals.

I've heard Ritchey makes wheels with zero dish, using OCR rims, and their own special hubs. Is
this true?

Wouldn't the flanges have to be closer together to do this? How does that affect wheel strength,
compared to having wider flange spacing, but asymmetric tension?

American Classic used to make narrow flange rear hubs (I haven't really looked at their new HF rear
hub to compare) that used the same size spoke on both sides. I have a wheel built on that hub that
is staying as straight and true as any other wheel.

It was certainly easier to build my AC rear wheel without having to worry about differing tension.

Ritchey makes hubs that yield an effectively dishless wheels, as did Sachs. The right (aka drive
side) flange stays at the same place, but the left flange moves in a little. Due to the OCR rim, the
bracing angle is better on the right side, and when you think about it, there's really no great
reason to make the bracing angle on the left side a lot shallower.

In fact, making the bracing angles similar means the spoke tension is much more uniform, so the
wheel builds easier and is more likely to stay true for life.

Built some wheel with them, nice altho lightish, rim.

<< At the same time, how is building with the "off center" rim? Is it really stronger and easier to

rim light also-wish a more normal weight rim was also offset. As for easier to build-nope, just like
any other-

Are they just effectively dishless, or actually dishless? I'm just curious.

I had some Mavic hubs which had narrower flange spacing too. Of course, these were all before
asymmetric rims came along.

I guess you're right, the real problem is the shallow bracing angle on the right side. Once you fix
that, the left side hardly matters, except...

Exactly.

The biggest problem we see in the Ritchey wheels are the built quality, not the components.

In the end, that's really what matters.

Had one on the Specialized Sirrus Pro I bought new last year for commuting. It was Ritchey built
with flat spokes. Failed spectacularly at 1800 miles. No, I didn't jump curbs with it. Ritchey did
replace the rim no questions asked.

I'm not sure (haven't bought any for a long, long time). I know the MTB wheels I used to build up
with Sachs hubs and Ritchey OCR rims were pretty close to dishless (but not quite).

I would guess that the road wheels still have some dish, just based on the fact they can only manage
a few mm's of offset at the spoke holes.

Anybody out there with a Ritchey wheel and a ruler? ;-)
