Exchanged messages recently with HWSNBN and he mentioned that you had been gifted the Crime Against Humanity long cage 7400 RD.

The rarest of the rare!

Rare and lucky to the guy who has it.
HWSNBN, I Like that, I like that- said in my Cobra Kai Kreese voice.

Speaking of a long cage DA-7400, I examined the possibility while I was cleaning the one up on the Prestige. The donor cage to be used is from a RD-6207 600. The bolt holding the cage on the DA is countersunk. Not on the 600. You either have to drill a countersink space on the 600 cage and use the DA bolt, or file/grind off some metal from the top of the 600 bolt. Otherwise, the bolt will drag on the derailleur body.

The what, now?
(Says the guy who just built up a bike with 7410 DA with a 12-25, but really misses the 12-30 on a couple of his other bikes)

The subject RD is a hybrid/mongrel made with 7400 body and 6207 long cage. HWSNBN acquired it from someone and passed it along to Pat. Note that the body is the same as a standard 7400 so it won't take a larger gear, but the long cage means Pat can use his beloved triple with up to a 28/30 cog. For larger gears with a DA RD, best to locate a 7703 or 7803 which is a true long cage DA unit that willk work with a 30/32 combination.

BTW, unless your RD hanger is super short (e.g. Cannondale) 7410/740X/7700 will easily shift up to a 28 or 30 in both large and inner chainrings. That setup is on several of my own bikes.
You'll probably have to adjust the dropout screws to pull it back farther in the dropouts and tighten the B screw, but it works

Needing more range out of that top level racing RD? Well, you can put on one of the company's MTB from the same era, or swap a cage onto your RD. Go to Velobase and look at the long cage RDs around your RD. In the case of the RD-7400, the 600 GS RD-6207 will work. Same RD with different finish and no indexing. As mentioned above, some other issues. Work around those and swap cages. Now you have a DA GS RD.

seypat

rccardr gives some good advice, as always. If a person is going to index with more range, best to use another RD. In this case, the DA GS/ triple will be for climbing rides in friction mode with 7/8 speed clusters.

This would be super useful for my 7410 setup. Just installed an 11-28 with a 52/42 crank, works great. Then I got a nicer crankset with 52/39 so thought "why not try that'? *Almost works* Just the slightest chain rub on the 39/12&11 combos, which you really shouldn't be in anyway. A GS rd would fix that though.

Carbon Centurion for sale (not mine), and it's even tex's size but he already has one . The guy want's $995. and I think he has that into it . Anyhow it's in the Ventura Ca. CL if you want to take a look .

genejockey 

You're running an 11-28 with 7410 crank, RD, and STIs? I am intrigued. Yesterday, I was riding the bike I mentioned above and a couple times I was thinking, "Boy, it would be nice to have a 28 right about now!" Not sure what I'd do with a 53x11, though.

shoota 

Almost, I’m using DT shifters. But yeah, all 7410. 11-28 works with a tricolor setup too.
I think you can find 12-28 cassettes out there too. And yeah, I don’t have a need for a 53t either, dropping that down increases your chances of your RD having enough wrap for your gearing.

Take those bar things off and it's not a bad looker.

A friend’s Prestige. It needed frame repair, hence repaint. He says the fork was so good he left it chrome.

seypat

This frame originated from HWSNBN. He's almost as legendary as Keyser Soze, but in a good way.

texaspandj

That's nice!
It appears HWSNBNish.

bamboobike4

I’m guessing in advice only.

markwesti 

Another PSA , not mine . I would go for it but not my size , need 56cm . 88' IM Expert 58cm , frame / fork and some goodies . OK price $135. If interested please see CL , Ca. LA Westside-Southbay

Here we go peeps. Stuff kept getting in the way, but I got er done. As close to original as I can get without the tubulars and the brake levers. I will take some pics with the tubulars and my other wheelsets to see what looks best. Then put on a different freewheel /brake pads/holders and give it a spin.

Classtime 

That I should a beauty. What are the bars? Original spec! And the levers? The look great! Leave the freewheel on and I bet you get a couple PRs on your everyday segments without trying.

rccardr 

You need 7400 levers?

seypat

Thanks for the offer. I'll keep these for now. They have adjustable springs. As I was looking up the 7400 levers, I think I saw a thread you were on that talked about them having a weakness. Or maybe that they were crazy expensive and the next lever in line had a problem.

seypat

The freewheel is a 12-20 with 15 and 16 sprockets in the middle. A little more range than the average corncob.

texaspandj

I Likey...a Lot!
Is that a 56?
The red accents
Yeah, the 7400 brake levers aren't great, but I'd be on the hunt for some.
Congratulations, is ok if I'm a bit envious?

seypat

It's a 54, so you can be envious.

Sunny today, so I can take outdoor pics even though it's cold. The color on the ST, forks, etc is a tweener. It's different than on the 85? IM. I think the bronze groups that came on the 84 Turbo and some other brands would look sweet on this bike.

Speaking of the cold that a lot of the country is experiencing, it will be 3 weeks today that I haven't had heat at my office. Bad fan motor and supply issues. HVAC company hasn't located a new one yet. At least my unit is in the middle of 8, so not exposed on 2 sides. The lowest the temperature has gone in the office is 53. Yesterday it got up to 65 like the outdoor temp.
