fixed / ss road bikes: what to look for
- bikes that use standard, easily-scrounged parts are best-- as opposed to odd bottom bracket or post sizes
- the higher the bottom bracket shell, the better.
- long "horizontal" dropouts.
- avoid stamped dropouts when possible. solid, forged = good.
- "three piece" aluminum cranks, preferably 170mm or less, with removable chainrings (some 70s designs have the large ring integrated)
- functional headset (though a rough one might just need grease and new bearings)
- aluminum road bars: ripe for flip-n-chop bullhorns!
- at least one salvagable brake and lever.
- don't underestimate the importance of choosing the right SIZE frame.

wheels:
- 700c clinchers = more tire options
- aluminum beats steel
- sealed bearings "r" awesome
- solid / bolt-on axles are ideal, but usually not essential
- get a mechanic to redish the rear wheel for a good chainline
- remove freewheel w/ chainwhip
- loctite fixed cog and bottom bracket lockring OR
- simply thread on a BMX freewheel....

Also: cottered cranks suck to deal with unless it is a super-beater. Then just leave them on.

Bikes: some but not enough

Avoidnot impossible, but just easier and better options)

27" if you want to go upgrade to 700C's
ANYTHING FRENCH, DUTCH, or Belgium
Vertical dropouts
knackered headsets and/or bottom brackets
One piece cranks
cotter cranks
stuck seat posts
stuck stems

other notes:

Just because it is Italian named
1. doesn't mean it was made in Italy
2. even if it were made in Italy, that it is not a POS

Spend your money wisely:

dropping $ on a paint job

vs.

buying a better frame to start with
better drive train
wheels

????

Cottered Cranks:

That hole that runs perpendicular to the spindle hole is the giveaway. It is plugged with a metal peg called a cotter. Hence the name.

one-piece (ashtabula) crank:

If it doesn't look like you can remove the crank from the BB without a saw, it's a one-piece. Easy to deal with, but generally crappy.

If you have 3 piece cranks, then the bottom bracket spindle, drive side crank arm(with the spider to attach to a chainring) and non-drive side crank arm will be separate pieces you have to attach to one another. If you have a one piece crankset, then the drive side and non-drive side cranks, and BB spindle will be the same piece of metal. If you have a crankset with an integrated chainring then it can be either of the two designs (I think there are one piece cranks with integrated chainrings, anyway), only a chainring will be permanently attached to the drive side crank arm.
