Subject: Odd DuraAce Jockey Wheels: what are they?

What kind of jockey wheels are these? They're on a DuraAce 7700ss
and the writing says "DuraAce sealed bearing pulley" on the lower but
they are different then most other jockey wheels I've seen.
Please cut & paste:

A tripod works wonders. Side lighting a bit helps,
having a featureless background without sharp shadows
helps. The pictures at
http://www.ucolick.org/~bjw/misc/rbt/brakebolts.html
(from a past RBT controversy) were taken on a table top
with an old 4mp Canon S45, tripod, macro, flash off,
main light was a 60 W desk lamp and the fill was
probably ambient room light, auto white balance. And
they're downsampled for the web. The color temp of the
desk lamp is not as much of a problem when photographing
metal objects as it warms up the coldness of the silver/gray
finish. Unfortunately, pictures of brakes aren't,
artistically, that interesting.

All digital does is let you do the same things you did in soup-based
photography faster--and without smelling of nasty chemicals.

All that training is transferrable, though, which is the best part. You
can't unlearn good lighting.

Yes and no. Nothing beats a properly printed black & white darkroom
image by a good printer on fiber based paper. But few care anymore and
the internet and the ease of digital photography has dumbed down
photography for the masses. Digital has gotten outstanding, and the only
technical area in online images and many printed images is that properly
exposed film still has about 2 stops more lattitude. But its subtle and
nobody cares anymore.

Compact and 12-27 doesn't really exceed the capacity, even officially.
DA states that when using a 53/39 and a 12-27, you still use the short
cage RD, so the compact will also not exceed it.

Triple version BUT when you ask for a 7700 DA RD these days, that's
what you get. Ours were relabeled DA 7703, labeled '7700'. BUT they
will work fine on a double setup.

My experience was that the 7800 short cage worked better. But I forgot to
mention I changed chains at the time from a SRAM PC991 to a Connex 9x1.
The connex seems a little smoother, maybe just the chain then?

It may be a technically good idea, and Shimano must believe in it
because they're still pushing it on low-end mechs [where riders don't
care what it looks like, or even see it], but I have one of these
things and it's huge. The ability to make the cage look not-so-long is
more than made up for by the gigantic pulleys. It's light and shifts
Dura-Acely, but it looks like a boat anchor. The current generation
triple has smaller pulleys.

Longer cage, smaller pulleys or shorter cage, larger pulleys I suppose.
Not sure which is better but on a 9speed compact double system I put a
7800 short cage on and it seems to be smoother, better shifting. Yes, I
running a 50/34 compact and a 12/27 which exceeds the derailleur
capacity but like many others have indicated, it works fine.

Yesbut, your lighting betrays your professionalism.

At a guess, you turned off the built-in flash (which would have
hilariously overexposed the derailer) and used a hot light, or as us
cheap photographers call them, "halogen work lights, $15 with stand on
sale."

Ok, I'm busted, I was a professional photographer but have dropped
it. Lighting is all judgement calls, Halogen is as you say the $15 choice
and not a good one because they have a very low Kelvin temperature
and will shift colors very warm to red. You can compensate to get
neutral tones but few amateurs would have a clue. I used the cheesy
on camera flash on the back side photo of the derailleur, front photo
no flash, all natural light. No reflectors, no nothing. Its all
judgement calls and seeing the light. I never shot digitally as a pro,
always used film. My original comment stands, its a 4M $150 Canon
digital. Amazing how convenient its all gotten. And a little Photoshop
tweaking never hurts. EBay here I come . . . . .

I cheated. I saw the photos, noted that Jobst was right about the
quality of the pics, and looked at the root level of your website
(rickschiller.com).

I'm a great fan of cheap and cheerful digicams, and especially Canon's
stuff (an A85 or A530, perchance?), but I really did think the flash
would have blown out the details from so close up, which it did not.
Maybe I have to get a better camera.

Or possibly a better photographer,

A520 Backside metal didn't have quite the same sheen, I shot it both ways
and this one looked better. Tweaking curves, contrast, levels, etc in
Photoshop and sharpening properly helps also. The highights actually are
more blown out in the backside photo, look at the metal just below the
upper 1/2 of the lower pulley on the left. But who cares or notices?

It looks like you have the triple version of the Dura Ace rear
d=E9railleur. It has larger pulley wheels to allow for more wrap without
resorting to a longer arm.

Yes, its a triple. The cage is about the size of a double, very clever. Thanks.
