Details
A clever adaptor which allows an EXTRA 4cm adjustment forward or back. Fits most single bolt micro adjust seatposts, this can offer a very radical saddle position, forward or back.

Conssaddle slides back
Prosdoes achieve setback
there is too much weight / torque added to the original seatpost. the saddle cannot grip in the correct position and always slips back. i will have to have someone weld it in place.

ConsThe bolt head pulled through on one but a bigger washer cured that. So, no, not really any cons.
ProsMakes for a more comfortable riding position
My wife was getting backache because she was hunched up despite her saddle being pushed as far back as possible. We fitted this adapter, set the saddle as far back as the 40cm would allow and no more backache. I then fitted one to my bike, setting my saddle back a further 25cm. Ace. A much more comfortable riding position. We've just, like last night, had our bikes stolen from the garage and one of my immediate thoughts, other than b......s, was would I still be able to get these for the replacement bikes. An excellent product.

Consneeded a bit of adpting with a file
Prosunique product that does the job
Rather expensive for what it is but I suppose a niche product one reason for that. Rather crudely made I had to file down the feet a bit to fit my stem bits, the B17 saddle on its own had no problem. The very thick paint doesnt help. I had no problem with any of the bolts and got a very nice secure fit
Pretty Good

Consbit pricey
Prosdoes the job
I needed to move my saddle back relative to my pedals and was already using a layback seatpost, so this seemed like the only option. It worked pretty well for me, a bit fiddly to fit, and the instructions are nonexistent. Had a bit of trouble with the saddle moving about so make sure the bolts are done up tightly. A bit pricey, but a lot cheaper than buying a new bike.

Conssilly design problems,
ProsClever, basically works,
It basically does what it's supposed to do, but, and it's a big but, the threading on the supplied shouldered bolt (to screw into the Saddle clamp) isn't long enough, and prevents the bolt from fully tightening into the clamp.

Fortunately I had a suitable metal spacer in the toolbox so the problem was solved, but simply supplying a fully threaded bolt would have solved this problem.

I have a fancy frame and seatpost and this doesn't work for me because the fittings are different. Course I didn't understand that till I had unwrapped it to try it.

Bang goes 20 quid. Just the risk with online shopping I guess.
Incompatible

Unfortunately this adapter was not compatible with my saddle or seatpost, which I had no way of knowing before I bought it due to the lack of technical information on the website. A schematic diagram with all dimensions would be very helpful. After having to purchase another seatpost I finally got it to fit, but it is very bulky and sits wider than the part of the saddle that it is clamped to.

ProsJust right for the job
I had looked all over to find the VK Saddle Adapter but couldn't find it. I wrote to VK to see if they would send me one directly. Then I found that SJS had it. ordered it online and got it over the pond within a week.

The adapter works just like it should. Now I can use my B67 saddle on my Dahon Speed TR.

Consnothing yet
Prosdoes everything needed
My B17 saddle would not go back far enough for me so after a lengthy search of layback seatposts I came across this...seemingly the answer to my prayers. As advertised it fit to my seatpost without any issues(should mention that it does not fit my other 2 seatposts on my mountain bikes so you all may not be so lucky). What can I say but it does exactaly what I need, gives me 40mm of offset so now my position is near perfect and I do not even think about it while riding. I will not say this will definitely solve everyone's issues however it did work for me so I say for 22 pounds it is worth a shot. Considering that you will be very lucky to find a seat post with close to 40mm of offset for anywhere near this price I would give this serious consideration if offset is what your after. Also when I say that it does not fit my other seat posts it is because the seat post pin will not fit, it is not a design flaw with the adaptor. Might need to go to lbs for correct bolts

Consheavy, ugly
Prossolves a problem
I have bought a 2nd hand bike off a friend and although we are about the same height we obviosuly weren't the same reach / leg length. I needed to get the saddle back 2cm beyond its furthest point. The gauge if the seatpost meant i couldnt buy a ready made setback. SJS delivered next day and the fitting was straightforward, It does look clunky but when you're sitting on the saddle nobody can see it!

Consdifficult to fit, causes other problems, bulky
Prosachieves setback
I got this to set my (B17) saddle further back than I could achieve with the saddle's rails. (I have insufficient room for the extra height of a setback seatpost.) It 'sort of' does the job. The protruding 'pseudorails' at the front fit in the bottom of the original saddle clamp reasonably satisfactorily, but I had to find a replacement top clamp and screw (in the spares box of a LBS) since all my top clamps had a central section that fits between the rails. On this adaptor there is no space for those projections just flat plate. I then found that the increased leverage of the setback saddle (+ myself!) made it very difficult to get the front clamp tight enough not to slip. Also, that leverage prevented my telescopic seatpost from sliding (next stop a Thudbuster?). It also adds about 20mm to the height. So: a mixed story. It is the only adaptor I could find, but I think I will be modifying it, or getting my local engineering shop to make something a little more sophisticated, or finding another solution. Service from SJS was exemplary, as usual.

Will This Adapter Fit A Dahon Bike?

None
SJS Customer Service:
Hi,

If your bike has a single bolt micro adjust style seatpost then this should hopefully fit and work.

Thanks.

SJS Customer Service:
Hi,

We normally fit our own Thorn seatposts to the Nomad bikes, if this is still what's fitted then this saddle adaptor can be fitted and will work fine.

Thanks.
