Title: Seat posts
Post by: lewis noble on January 07, 2014, 03:04:50 PM
Hello guys - happy pedalling in 2014

When setting up / adjusting a bike, I always found that getting the saddle angle right is about the hardest to sort out.  Nose too far down and hands / wrists come under strain.  Too far up, and the discomfort can be profound.

And the notches on these supposedly micro adjustable posts never seem quite right.  When I do eventually get it right, I am tempted to weld the whole lot together to keep it that way!!

Years / decades ago, I had a bike where the seatpost had two securing bolts, and the angle was adjusted by loosening one, tightening the other, then securing both.  What are they called??  And are they still available??  My saddle is a Thorn Velo, suits me fine.

My Thomson Elite seatpost operates that way and has the angles marked on it. Not cheap but good quality.

Lewis,

If you find the notches come in just the "wrong* position, reversing the clamp (front-to-rear) can sometimes provide just the right combination to work.

The Nitto S83 is a fine 2-bolt post as well, and also not inexpensive: http://www.sjscycles.co.uk/nitto-s-83-seat-post-272-mm-prod27448/

Best,

Dan.

Dan, there are of course a lot of considerably lower cost two-bolt seat posts on that SJS page. Ritchey, Easton and others which should also work quite well.

Thanks guys, more to choose from than I thought - now I know what to look for.

I have always liked Easton products in the past, and will probably go for one of those.

Ordered an Easton via SJSC - the choice narrows down a bit when you look at the size you need, availability etc.  Now fitted . . . . and what a difference!!   Posture and angle sorted out within 20 minutes, after weeks of fiddling, so I am well pleased.

Thanks for pointing me in the right direction, everyone.

Hi Lewis,

Just curious - which Easton did you eventually settle on?

Hi All,

I settled for the Easton EA50 MTB.  Not too expensive, and available in 350 mm x 27.2.  300mm is barely long enough for me to get the height right, and I end up on or beyond the limit line.

Seems very nicely made.  No problems fitting, though I put the saddle on in my workshop / garage, the wrong way round.  The nose in the air surprised me, and attracted ribald comments from neighbours, then I worked it out. 

So I am happy. 

Lewis

Hi Pete

That sleeve you've got over the seatpost/collar/seat tube looks interesting, is it waterproof? If so, where would one get such a thing?
Incidentally, I bought a Thomson seatpost a couple of weeks ago, and I like it so much I bought a second one for another bike.  ;D

Looks like a section of inner tube.

To keep water out of the seat tube and possibly show any seat post slippage??

Hi Chris M,
TO keep water and dirt out, plus to help stop anyone remove my seatpost.
It will not slip  :)

What makes a good seatpost? I've got the standard Thorn one and have no idea why I'd change it.

Hi Well,

1st, Strong

2nd, Light

3rd, Easy to adjust

4th, Design

5th, Well Build

So I mean a Thorn seatpost is very strong, Not Light and hard to level But is of low cost!
A Thomson is Very Very Strong, Light (there is lighter But not as Strong), of very good Design, Very Well Made (Made in the USA), Easy to level.
But it comes with a high price  :o
