Can I use my seatpost back to front?

Postby Gwaredd » Tue Apr 02, 2013 10:41 am

Hi all. I say mine, but it's my wife's bike. Picked up a lovely little Kona for her, but the cockpit is a bit too long & is hurting her neck. I've ordered a 60mm 30 deg stem to bring her closer & more upright (current stem is 110mm 6 deg) but have also noticed that the Easton EA50 seatpost kicks the seat rearwards too.

Before I buy a new in-line post, I was wondering if I could simply spin it around the other way, so the kick is facing forwards instead?

Is this a big no-no?

Possibly, but it depends on whether you can get the saddle at the right angle with the post reversed. Only one way to find out.

It may be OK, it may not, some designs you won't get the saddle level due to the layback angle of the seat tube (you can see in that pic you posted how it's catered for)....

Buy and inline post and sell the setback would be my advice - or get a frame the right size!

Frame fits her perfectly, especially legs - just need to tweak the cockpit with said components to get it just right.

Don't do it, it'll look stupid.

Eh, you get the frame size to suite the reach (which is clearly too long for hers) as that can only be tweaked by a max of about 90mm, the massive adjustment on the seatpost (circa 300mm adjustment) takes care of the legs!

The reach is only marginally too long for her with a 110mm stem & setback seat post, so is clearly within adjustable tolerance (small frame btw) You put the seatpost up 300mm to make you legs fit a frame, chances are your ass will be pointing to the sky & you'll be in a TDF racer pose :lol:

I'll agree that you buy a frame size that fits all, then tweak it via stem etc depending on the shape of your body. I'm 6'3" but ride a medium framed Trek EX9 as I found the cockpit on a large waaaay to long for my body. I use a high rise stem & bars & it's the most comfortable bike I've ever sat on.

I'd fit the new stem first and see how she goes. I think you'll struggle to get the seat to the correct angle with the post back to front.

An inline will grab 20-25mm, and you have 15-20mm adjust by sliding the saddle anyway.
