This frame was built sometime in the 1970s by Francisco Cuevas, a Spanish framebuilder living in Manhattan at the time.  For those who are curious about him and his work here are a couple of links:

This bike came to me in parts from a friend who was living in NYC.  The frame had no decals or markings but has "cuevas" embossed in the top of the seat stays.  Has Campy headset and Campy Record hubs with Campy rims.  Now with it's fresh powercoating, new decals from the grandson of Francisco, updated wheels and tires, and lots of Campy parts it is ready for a new owner.  Standover height is 33.5".  My buddy, Mike, and I expected one of us would keep it, but neither of us can really appreciate this bike as much as maybe someone who once owned one, or wish they had.  If you are interested get in touch and I will email all of the dimensions and details, or soon I will get it posted amongst the bikes to sell page...Rusty

This bike I found on eBay looking as you see it in the first photo.   Came with Shimano 600 5-speed, reflectors, down tube shifters, peeling decals and cloudy clear coat.  I removed all the components and polished the whole frame (photo #3).  Then Jay in Chicago bought the frameset from me and over most of the winter of 2006-7 built up the bike directly above. A very sweet singlespeed.

The Kestrel 200SC frame on the left came with a Dura-Ace 9-speed group which was removed.  The carbon was painted white, by Kestrel, but I don't think they knew how to make paint stick to carbon back then. It was pretty scruffy.  The stem was cut off flush with the top of the steerer tube because it was stuck.  Also the seat post was stuck in the seat tube so that's why it sold for $150.

So some nut named Robert in Florida bought the frame then decided to torture me by sending me the above photo (right).  Looks a bit better to me!  Beautiful paint job on the frame, nice Spinergy wheels and looks like a brand new SRAM Force group on it. Nice!

A classic Waterford 64cm steel frame mated to a Look carbon fiber fork. Cane Creek headset, Henry James dropouts, American Classic seatpost, Reynolds 753 steel lugged tubing and white decals on British racing green paint. Frame, headset and seatpost weight 5.2 lbs. Fork weighs 380 grams.

Jason built it up with Mavic wheels, SRAM Rival components and a Fizik saddle. Nice!
