Dura Ace triple group, neo retro

I've decided to go all Campy in my life, so this is moving on, enjoy it as I did. This was sort of a do it all, neo-retro randonneuring idea that came together before I decided on a different course. I'd like to try to keep this together for now, but my mind could be changed if there's interest. Pictured on the bike, but I can provide more pics as it's been parted out.

$225 shipped or best reasonable offer Most of that cost is in the RD. Happy to make a nice deal for a forum member.

Included are:

--10 speed indexed 7900 downtube shifters. These are currently mounted on a vintage shimano clamp and backplates. I think the vintage backplates are better because they're curve to fit the downtube, but I will include the original backplates if you want.

--7700gs triple rear derailleur. This is kind of a rare one. The large pulley wheel wraps more chain to accommodate the triple.

--7703 triple front derailleur.

--FSA Gossamer crankset and BSA threaded BB. Not much to say. It's a triple, it's silver. It's not very cool. Get a Dura Ace one. 50-39-30 rings.

--TRP RRL drillium levers with gum hoods. Pretty cool. Very low mileage. I still have the box and the angle inserts.

--FREE 105 cassette, 11-28. Pretty high mileage. Throwing it in as a bonus, but up to you.

Happy to consider trades for modern Campy stuff, too.

Question: so you can mount indexing shimano downtube shifters designed for braze ons to vintage shimano clamp? I'll have to try that out.

Yes, but the clamp must be for SIS shifters. This was a generic pair of six speed.

What a cool bike -- any aspirations of running 650b's with those long reach brakes? (oops- never mind, just saw the line about going all Campy)

Braze on FD? Designed for a 53/39 pairing I'm guessing??? (the spec page mentions a 14T minimum between top and intermediate)

You are correct, I think. The only difference between using a DA 7700 crank set for a triple or double was the middle ring. The middle ring for a triple had eyelets onto which the granny ring was mounted. The same crank set was used, with a wider BB spindle to accommodate the chain line and clearance from the stays.

It was a good idea. It did not catch on, which is why the middle ring now sells for $100 or more. That middle ring can be used the same way with other crank sets, making them triples with the wider spindles on a trial and error basis. I have no idea if there were failure issues with bolting a ring to a ring. TA Specialties seems to have it down.

DA 7700 crank sets start to deteriorate cosmetically as soon as you look at them. They are light and polish up well once you decide to remove the anodizing. Octalink bottom brackets are durable and easy to mount, except of course, the 7700, which is lighter but not as durable. I've always thought that Shimano could have dressed up the 6500 crankset a bit and had a better 7700.

The 7410 with the 7700's triple middle ring, on a wider square-taper BB, that would be a honey with this group.

The triple DA group was really, really nice, light and versatile and smooth. That long-cage RD is hard to find under $100 and the matching FD a bonus, as well. The shifters/FD/RD of this group are not that far off of OP's asking price, brake levers and his other stuff make it a pretty sweet deal. I'm not a huge Gossamer fan (crank set and BB are fine, just not gossamer-light), but he's right, it's triple, it's silver, weighs about the same as the 10-speed Ultegra, and looks more in line with the age of the frame.

IMO, great parts but not really a group. If you part out individually, you'll make your asking price back with no problem.

That RD is pretty hard to find on its own.

GLWS.

To add to @RobbieTunes comments: The 118mm octalink DA bb (7703) is impossible to find (harder than the RD). For the double, a lot of people went to the 7710 with 109.5mm as it is more durable ... spendy, but still available.
