Very true. You need to buy Record to make sure you get all the bells an whistles, but a good look at the spare parts catalogue may allow you to save quite a few quid by seeing which bell and which whistle is different to Chorus.

Some things, like my 2006 Chorus Ergos, are Record except for the ratchet G spring housing. Record is drilled to make it lighter and Chorus is plain. Other than that, the units are identical except for my brake levers that say "Chorus" on them.

Yeh and I bet every cattle grid gives you a right ole Chime

Good one!

I never noticed my puns.
Well done!

Stainless steeel seat posts, I wonder why the world wide cycle industry never thought of it before?

I mean, all those countless millions of dollars spent on research and development, the accumulated totals of race results, hours in the saddle, customer feed back and yet untill this day, nobody in the entirety of human history thought of a stainles steel seat post! What better way, I ask you, to add extra weight, extra expence and redundant strength to a bicycle? Maybe this is the break through that the world has been waiting for??? In fact lets push the boat out and go the full hog. Never mind tubular steel posts, why not "invent" a solid stainless steel seat post? Just think about the benefits, under normal conditions, you're unlikley to bend it and it's never going to rust.

And if you were diligent enough to make it from 304L a collision with an exploding nitric acid tanker would mean your fillings and intact seat post could be buried together....

But each to their own, there are plenty of far more useless devices for cycles.

Hi,
I think that most if not all the steel alloy seat posts including Titanium etc are a tube that is sleeved onto another boss for the seat clamp.
This is the only cheaper way to get a quality tube for the purpose without over expense in a one piece unit.
Thats why aluminium alloy is used as its light enough to easily produce a one piece moulding that is also cheap.
Tubing can be mass produced and cut to length, then pushed onto a boss.

Edited-
Ah even my cheap alu alloy seat pillars are sleeved too.
But the tube section is also turned, this is probably to acheive actual size of frame tube which varies from bike to bike,25, 26.8, 27, 30 etc, etc.

Moots seat pin; no shims, no press fits, all lovely.

cheers
