I have tried to resource a VK Adaptor but it doesn't appear on their website now. Has anyone any idea
where I could buy a saddle extension/adjustor.


I have an unused one (somewhere!) PM me, we can reach a price, I'm sure.
Or St john St do a long layback post its either Zoom or Thorn brand, about £25 as I remember...I can probably find it at a more sensible time of day, if you're stuck.....its been on here, too!

just in case you have not seen one before;

SR Sakae Ringyo MTE-100 seat post

Image

-occasionally pops up on ebay, not sure how many sizes were made.

Also Easton EA-50 layback seatpost (old model NLA new now AFAIK)

Image

similar ones have been called 'EA50 road', 'EA50 road 2007', '3D- 2010'.

SJS thorn branded one

Image

http://www.sjscycles.co.uk/thorn-micro-adjust-alloy-seat-post-with-large-lay-back-400mm-x-272mm-prod23725/

seems a good choice because you can buy it new and it isn't too expensive, but it is only listed in 27.2mm dia.

cheers

That EA 50 post may not have measurably more layback than a cheap (kalloy, etc) hockey stick post....the first photo in this thread is........

there are lots of different EA50 posts, and many (including the current two-bolt version) do not have much layback at all. Just need to find the right version...

edit- apologies Colin, that is the same post isn't it... :oops: I quite like the Hockey stick ones BTW; unlike the ones with serrated mating surfaces, they are infinitely adjustable, and have the great advantage that if they do slip, they are not instantly ruined.

The other alternative might be a Thomson Layback post?

I've used one of the Thompson laybacks - astonishing quality!

the thompson posts are very pretty but even the layback one doesn't actually have very much layback. The ones in Colin's picture have as much or more layback than that.

Having fitted one recently I fully agree with you. Thompsons seatpost offered me the amount of layback I needed which is more than the Velo Orange layback seatpost and the System EX which I had fitted and the degree of adjustment it offers is fantastic.

Thanks everyone. I contacted SJS cycles and they can supply a Saddle Adjuster or they suggested
a Thorn Lay Back seatpost. I'll study both then make my decision. Great imput from everyone.

i DONT REALLY KNOW MUCH ABOUT ACCESSORIES SINCE ABOUT 1970ish so I'm not sure of my ground. so please be gentle :D :D
But If you took a rather long A-stem extension [a round cylindrical type and cut off the bar end and use the fork end on the seat post then use the old-fashioned saddle clamp and adjust it back to where you want it. I do have a similar arrangement looking at me on the desk.
As i say I only got an idea, but not the technicalities regarding sizes.
Just a thought!

Brucey,

That tells me nothing more than,

1. You can Google and download pics to your computer.

2. You can then run them in a programme and draw yellow lines.

If you have had first hand and personal experience of having both seatposts at the same time for comparison, please elaborate on your findings as I had and finding the Thomson offered more layback than the Velo Orange, I sold the Velo Orange one on this forum.

As an aside to that I remember Creppelo giving a very good account of his experience with the Velo Orange layback seatpost and why because of the width of the bracket the rails on a brooks saddle can't go far enough back, again experience gleaned from having one, not sitting behind a computer going flat out on Google.

So as I previously said having both seatposts in question. One sold on this forum and one on a bike pictured over on the Touring and Expedition section perhaps you can stick up a pic or two of both seatposts that you currently have examined and measured with a saddle fitted between the rails without resorting to Google.
