I currently have my fixie built up on a Lotus Classique frame. It has Tange #2 butted tubing and is in ok shape. We just got in an old Holdsworth Special at work today (took it in on trade, I can get it for $15) it is built with Reynolds 531 double butted tubing throughout. It's the same size, has 73/73 angles and is 120 rear spaced (compared to 126 on my Lotus) The paint is much nicer and the overall quality of the frame seems significantly higher. I guess it was marketed as a club racer/touring frame. It has mounts for fenders on it so it doesn't have that performance road bike look, but it's a really cool frame.

So, should I swap out my Lotus frame to this one or not? I just can't decide.

Get the Holdsworth but don't swap out your Lotus for it. Slowly build it up as a second fixie as you can never have too many bikes! And it's not like you're spending vast amounts of your hard earned money on it...just $15! Or just keep it as a sparre frame just in case.

yep, for $15 it's worth having both.

or, you could sell it to me for $15.
