ProsGood Looking
Well made, easy to fit and very comfortable with adjustable movement. Needed a shim to fit my bike but SJS have a good range of these to suit most bikes.

ProsDoes the job well
My bike doesn't have rear suspension and biking on the Berks downs and the like was very uncomfortable until I got this sprung seat post. I adjusted the tension to suit my weight (12 stones) and it coped very well, very pleased with the product.

Does this have a micro adjustment to alter the angle of the saddle?
01 Aug 2020
Yes it falls into the category of a micro adjust seat post BUT the adjustment is via toothed plates so the teeth determine the adjustment increments RT 03/08/2020
What is the spring travel for this dropper post?
17 Sep 2019
Hi there,

The travel on this seat post should be in the region of 40mm.

Do you have a 31.6mm version of this or can you supply a shim that would work with this?
07 Feb 2019
Yes we would have a shim to fit -

Thanks - 08/02/19

Yes it can. You will need to use a hex key and tighten or loosen the bolt inside of the bottom of the tube

Will This Fit An Ancient (20Yr) Raleigh Mtb?
04 Aug 2015
I've measured carefully with a ruler the seat post to be 1inch/25mm, but I can't measure this precisely.I need a replacement seat post for my old Raleigh pub bike.

Is the 25.4mm diameter likely to fit this old MTB?

It is possible that the correct size seatpost is 25.4mm as this is exactly 1 Inch, but as Raleigh are well known for using unusual sizes on some of their old bikes it could indeed be exactly 25mm in which case this seatpost would not fit. I would recommend trying to find somebody with a set of callipers to measure the distance accurately.
