Seatpost diameter

revyakin said:

Hi all,

I don't have any experience whatsoever with m.b. parts, so...

I am planing to get my fiance a Thudbuster seatpost for her TREK 4300.
These seatposts come in 26.8mm, 27.2mm and 30.9mm diameters. The
original seatpost says it's 29.2 mm. What do I do? If I get a 27.2
post, is there a way to make it fit?

General question: can a Thudbuster seatpost serve as a poor man's
solution to reduce butt pain when riding a hardtail, as opposed to
spending $1500+ on a full suspendion bike? I understand that a
Thudbuster on a hardtail will not feel as a good as a real FS bike,
but...

Thank you in advance. Yeah... could please post your replies here?

most bike shops can order in special shims to compensate for the varying
diameter discrepencies. I had to do the same thing when I put a suspension
seat post on my hubby's bike.

As Penny said, you can buy shims.

It does help some, and allows you to stay seated over some rough sections
where you'd usually have to stand. Just not some of the really rough stuff
that you could sit through on an FS.

To reply to me, drop the attitude (from my e-mail address, at least)

If you had a caliber handy you could use it and you
couldn't go wrong.

Nor does it "substitute" an FS. The idea behind an FS is that the rear
wheel stays on the ground while going over bumps - the comfort ride
is a by-product of this. So a suspension seat post will probably provide
the comfort of an FS, but NOT the purpose.

Thanks! Well, at this point comfort is the most important thing. Glad
to hear that the seatpost I want does seem to help in that respect.

Allright, will look for the shims locally! Just ordered a 27.2 mm Thudbuster.
