Fastback Seat Stays
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?

Is there a point to these type of seat stays?
Do they make a bike a better sprinter? Climber? More comfort?

'80 windsor touring elite

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.

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 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 @b dub has it now):
A Serotta Coeur d'Acier which passed through my hands a couple years ago:
My Redcay:

My Atala Super Pro:

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

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...
