Hi bfssfg,
I know it's late, but that's when I tend to be on eBay and such looking for a new lightweight track frame. I thought I'd seen pretty much all the options until tonight. What I've been looking for is a light weight frame (most likely aluminum) with geometry that I could take to the track if I want in the $0-600 price range.
I ended up finding this - a Pake French 75 - which sells new with a carbon fork for $499.99
-The frame is 3.5 lbs of 7005 Aluminum (pretty sure this is on the light side of things) and the fork is 1.4 lbs uncut.
-Seat tube and head tube angles = 75, bb drops 58mm, and wheelbase is 984 mm, and rake is 38mm (measurements are for 59cm)
-It's in my price range
Is there anything I'm missing here or is this the frame I've been looking for??
