Waterford seatpost

sjbraun-<< Has anyone tried using a 27.2mm seatpost in a Waterford frame that was designed for
27.4mm seatposts? Did you need a shim make this combination work?

No shim for .2mm afaik...use a 27.4, don't use a 27.2mm-

Steve: Would strongly encourage you to look for a 27.4; they come up on Ebay occasionally. I know
Thomsom makes/made one. In the mean time you may be able to make do with an aluminum soda can shim
(Hey, it worked for Greg Lemond in that most famous of TDF finishes!). Why they ever went 27.4 we'll
never know, but apparently they thought better of it eventually. Good luck.

Many LBS [like us!] stock various brands of 27.4 as well.

(And I agree with the crowd that you should get the right size and not shim
it.)

They used a thinner-walled 853 seatmast. It's plenty strong and saves a little bit of weight. Their
frames now use a
27.2 post, but even during the days of the 27.4 post on the 1200 and 2200 frames, they would build
for 27.2 upon request.

Does this mean that Waterford is now using a "heavier" seat tube to accomodate 27.2 seat post?

That's my guess. The advantage of saving a small amount weight was likely outweighed by the
advantage of using a more conventional seatpost size.

"Heavier"? "Standard"? It's all semantics isn't it? For a hundred years or so, a 28.6 outer diamter
with a 25.4 post was "standard". Among Reynolds and similar frames, 27.2 seatposts have been the
'standard" gauge for some forty plus years. Tangential to the concurrent discussion about
"improvements", Waterford's designers were able to shave a few grams with impunity by going to 27.4
seatposts. Here, we thought that was reasonable. But apparently there was a crowd of whiners such
that Waterford relented.

I recall the first time I saw a 27.4 - a BobJackson Lugano time trial bike - and thinking that was a
clever way to drop a tad of metal. But I was young and impressionable.

A local frame builder states that (in his opinion) seatposts used standard 28.6 mm seat tubes
*should* be 27.4 mm. His contention is that the seat tube wall thickness is typically .6 mm at the
top- do the math (28.6 - 1.2 = 27.4), and the seat post *should be* 27.4 mm.

Why aren't they on most bikes built with standard steel tubing? Because (according to this guy) most
builders are sloppy and overheat the seat cluster, distorting the metal. They end up only reaming
the tube to 27.2 to avoid thin spots in the distorted lug/tube.

His seat tubes always take a 27.4 mm post. In fact, you have to already have a 27.4 mm seatpost or
buy one from him, because he really hates people cranking down the pinch bolt to make a 27.2 work.

Will a vacuum pump allow me to pump up my tires with a vacuum? That ought to be lighter than
hydrogen and eliminate the fire hazard.

Are there any vacuum frame pumps made?
