I think this is the coolest thing ever!

I want to buy a frameset with the seat tube clamp on the seat stays. Any suggestions?

Trek 660.

Or 760:

Some 3Rensho and some of the Raleigh Pros, I think Mk II to Mk IV.

Is there a point to these type of seat stays?

Do they make a bike a better sprinter? Climber? More comfort?

I'm pretty sure it is just for looks.

my '88 trek 400t had them too, but i wouldn't promote that one unless i were selling it again.

now my '80 trek 414 didn't have them. but that was a really nice bicycle.

Dave started at Waterford, no?

He spent several years at Serotta before he went to Waterford where he spent several more years before hanging out his shingle. The man is talented.

Here is my 1983 fillet brazed Ritchey Everest

Lugwork, in general, but the seat cluster in particular, is one of the best ways for framebuilders to distinguish their work. As you can see from all the images posted to this thread, there is quite a bit of variety in fastback seatstay treatment.

Here are a number of shots of fastback seat clusters on some of my bikes. Here's my RRB's cluster:

A Trek 770 I used to own (Trek did a lot with these "pluggable" seat lugs to simplify construction - I think [MENTION=104946]b dub[/MENTION] has it now):

I've seen this treatment on some of Chris Bishop's frames

If you have the money...

The 80s Cinelli I recently posted in "Are You Looking...?" has fastback stays too.

The OP's picture is actually my very own TS Issac 1980 Olympic Team frame.

The seat lug is one of my favorite features on this unidentified frame that I have had for a few years, now. I think it is a Roberts, but no solid evidence - yet...
