Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

drops

the word "drops" is used seemingly to refer to both a kind of handlebar, and a kind of frame that the rear wheel's axle sits in.

What gives?

I think you are confusing drops and dropouts. Drops are the typical road style handlebars. Dropouts are where your wheels go.

If you want to have some real fun, go into the bike mechanic forum and ask what "pitch" refers to.

there is only one correct definition of pitch when referring to chains. it's not opinion or semantics, those who refer to 1/8" and 3/32" widths as pitch are just wrong.

from sheldon brown's glossary entry on pitch:

Pitch

The pitch of a chain is the distance between adjacent drive rollers. All modern bicycles use 1/2" pitch. Some older chains, especially those used on track bicycles used 1" pitch chain (see skip link and block chain.) For a while, Shimano experimented with a 10 mm pitch for track use, but it never caught on.

Sometimes people mistakenly refer to "track pitch" vs. "road pitch" when they are really referring to the wider (1/8") sprockets used on single-speed bicycles, instead of the 3/32" thick sprockets used on derailer-equipped bicycles.

Drops are, more technically, the part of a drop handlebar below the brakes. As quoted above, Sheldon Brown has an excellent glossary. It has an explanation of the clipless versus clip pedal systems as well.

That was my whole point. Pitch seems to be used for a whole host of different measurements and meanings, one of which Brunning so eloquently and forcefully defended. To wit, his definitive reply illustrates the type of back and forth that routinely develops on these topics with the expert bike mechanics and linguists found in other parts of our friendly confines.

Anyway...

Pitch is the angle between the top tube and the down tube. Oh no...wait...it's the distance between the spokes measured at the midpoint between the rim and the hub. The offset of the fork is commonly called pitch-FORK or rake, I am not sure.

i'm not so sure about bike mechanic jargon, but i believe brunning and sheldon brown have the actual 'correct' definition, regardless of what it's actually used for. i'm only saying this because it is used in other fields (such as engineering and technology). an example:
with CCDs (the sensing element of a digital camera or spectrometer), the 'pitch' refers to the distance between the centerpoints of adjacent pixels.

not necessarily. track bikes don't have dropouts. they have track ends.

Yeah yeah yeah, I've read Sheldon's site. Just trying to offer explaination without confusing the lad.
With such a basic question I gave a rather basic answer.
