Can I reverse my seat post?

[Stantheman]

as above, can I simply remove me seat / saddle turn the seat post 90 degree refit the sitting area and go?

You probably don't mean 90 degrees as thats sideways, but 180 doesn't work either as the tilt of the clamp is wrong.

If you really want to you can but it might look a bit daft. are you sure your stem isnt to long or frame to large to start with.
An insine seatpost may do the trick also

No, no, no..............and no again!

I think this one has been discussed before. Search on Seatpost and something might turn up. I think the general conclusion was the saddle angle would end up all crook.

If you want to achieve a more forward saddle position - have a look at inline seat posts http://www.chainreactioncycles.com/thomson-elite-inline-seatpost/rp-prod6066 or the profile fast forward seat post.

It depends how your seatpost clamp works, it's perfectky possible with all my bikes.

 

[Stantheman]

Yes sorry 180 degree, I do want to try and get my seat forward a bit more and I have already changed the stem. The frame on my bike is probably a bit big for me but I am going to have to live with it for a bit longer so looking at what I can change to make it work.

My current post is a layback so looks like a inline would work cheers guys.

The frame on my bike is probably a bit big for me

Big frames often have a slacker seat-tube angle but this makes a very small difference in saddle layback. i.e. as you extend the post higher you get more layback but only a little.
You frame maybe to long in top tube, which is a different issue, "fixed" by shorter stem.

Saddle layback sets the horizontal distance to the pedals (the X in [x,y] coordinates).
You can reduce x by moving the pedals closer to the bottom bracket, ie shorter cranks.

That would also shorten y though, which the rider might not want.

The simple answer is, if the nuts and bolts of the clamp etc allow it, then yes.

Don't listen to anyone who says you should abide by their own sense of what makes a bike fit. If it works for you to have the seatpost flipped, go for it.

(It didn't for me, by the way. And incidentally I've got a carbon inline one you could try out if you live anywhere near me.)

 

[Stantheman]

@ Cyclist33, thanks for the offer I'm near cardiff so a bit to far. I might just turn it around and see what happens.

As Michael says - the angle of the seat tube will be more or less the same as a smaller frame so you already have the seat in exactly the same position as you would have in a smaller frame.

You need to look at the front to make any adjustment.

If (1) the clamp angle is not adjustable, and (2) the saddle rails are not parallel to the top of the saddle, you may have a saddle angle problem.
