Schwinn Paramount?

@juvela The bottom bracket says Japan and 36x24T

thank you

this should eliminate Wiscoland as a possible locus of nativity

frame appears "quality production" & not "artisanal"

one possibility you might wish to explore, if only to eliminate it from consideration, is that the frame may have been contract manufactured for a U.S. reseller

two names you might wish to investigate in this regard are Performance and PAB - Palo Alto Bcycle

unfortunately for your researches it shows no specific detail associated with a particular name

unable to make any guesses as to possible maker or nominal brand

keep in mind also that an Italian dimension shell does not necessarily indicate an Italian origin cycle/frameset, as Italian dimension cycles and framesets have been produced as well in Belgium and in Mexico

@juvela Thanks for all of the info. I’m going to keep searching for what it is. In the meantime I’m going to get it to my liking and ride the heck out of it. Thanks again! I’ll keep you posted if I find anymore clues.

one thing forgot to mention earlier is the joinery of the taper tubes to the frame ends

there are different techniques/details as to how this is done which can be helpful clues for ruling in or out specific identification candidates

if you look at some frames online this would be one spot to check to see how it compares with the subject frame...

@juvela Thanks, I appreciate the extra tidbit!

decent bike most likely built for someone middle of the road components but its not a paramount

So finally getting around to fixing this bike up. Think the stamp on the bottom bracket is actually RWC 008. I took the for off and it’s stamped on the steer tube 008 on one side and 55 (size?) with the Columbus dove logo. Not sure if this gets us any closer to a manufacturer. Anybody know what RWC could stand for? And the 008 both on bottom bracket and steer tube? Serial # or measurement?

Some pictures on the steer tube.

Could this be a Dave Moulton bike?

see nothing to suggest it - but then am certainly no expert on his produce

it does not show enough detail work to be one of his bespoke products

as you may know, he had a limited production line of frames for a time called FUSO

the "55" marking on the steerer indicates the size of frame the fork is intended for, as measured centre-to-centre

it is not a marking one would be likely to encounter on anything bespoke - it suggests "production"

in addition to BMZ there are other Italian manufacturers who produced quality frames in quantity for private labelling by bike shops and distributors

estimate date to be ~1983-1984

Just picked up this bike from a yard sale last week. Figured it was a decent bike because of the Shimano 105 components and campagnolo dropouts. Also it’s a 22” frame which is the size I ride. Has a Columbus sticker on it but no other decals. Possibly a repaint. The serial on the bottom bracket is hard to read. My first though was Schwinn Paramount but the top of the seat stays do not look correct. Also reinforcements behind the fork at the fork crown look different than I’ve seen. I’m including some pictures. Looking for advice if it’s a paramount and year or if it’s something else what it could be. Thanks!

Doesn't look like a Paramount. I think the serial numbers were stamped on the dropout.

Determine the Manufacturing Date

The Earliest Paramount Serial Numbers The very first Paramounts seemed to have had serial numbers starting with “A” followed by two or three digits. This seems to have been a system started by Emil Wastyn. We found a very early
