Got a GT Power Series Pro 2010...need to install a 22.2 seat

[snertos]

Hi there people.
I have just bought a GT Power Series Pro BMX and am a big chap so want to install a laid back seatpost.
Only trouble is, all the old skool laid back posts are 22.2mm and this seatpost housing is 27.2mm and I can't find a shim anywhere to make it fit!
Any help offered would be great.
Or a laid back that would just fit straight on to a 27.2 housing would do.

Try posting this in the BMX section but I don't think you'll find a proper old-school layback post to fit. There are plenty of new layback seatposts in 27.2 just look at any bike website not just BMX shops but the maximum layback is about an inch.
