Any1 know of any other brand of seat post that does a layback like this thompson one http://www.chainreactioncycles.com/Models.aspx?ModelID=8569   but cheaper!!!!!! an All mountain one will be ok, it doesnt have to be heavy duty, im buying this aswell as a normal more heavy duty one and i willl have two saddles, so that i can just quickly swap them over depending the type of riding i will that day.

Bong,
I think you may find the layback post will position you very poorly for pedalling. With my post fully extended, I need to slide my saddle forward so that I am not seated above my rear axle.
I think you will most likely be better off with an inline post than a layback option.

surely that would depend what bike he is fitting it too and the seat tube angle as to how the saddle is positioned above and behind slightly the bottom bracket

If I am not mistaken, he will be fitting it to his new Supreme. The frame has a pretty slack seat tube angle, that will put him in a position that is not quite over the rear axle but close enough as he extends his seat for days that he will pedal.

I don't think a layback is a good idea.. Just put a longer seatpost on, and then find the correct height you need for pedalling, then work out saddle position from there.

Noted guys, i will see how i get on with a normal inline 1st then, i was just thinkning cos my frame is a s/m and im 6ft1 that a layback will help me stretch out a bit more on days that i may be stupid enough to think about riding uphills  without having to comprimise the handling by fitting a longer stem.

Just remember you will need to have the seatpost go to just below the lower weld on the top tube. I think it is about 110mm for the l/xl frames.
Check what it is for your mini bike!!!
A Thomson post will give you enough height but won't allow you to get your seat as low as you want if you use the 410mm post.

I know somewhere there might be a layback Thompson post going for about £25
its a short length (about 270mm) and 27.2mm but you could always shim it?

Nah im not really in to shims etc, thanks anyhow tho mate.

I just had a look tonight and the orginal seatpost on my mini dh was set back by 20mm , so im gonna have a hunt for either a layback one or a decent setback one instead of a inline.
