About Seat Posts

A good quality seat post will save weight and hold your saddle securely. Seatposts are made in various materials, alloy and carbon being the two most common, alloy posts are lightweight, durable and cost efficient, while carbon posts are the popular choice for top end machines. Seat posts vary in where they hold the saddle relative to their own centre line so make sure you have enough adjustment on your saddle rails to allow for this or you could end up with your saddle too far forwards. A seat post needs to fit your frame exactly and are measured by as little as 0.2mm. When choosing a new one, either read off the measurement from your old seat post or measure it carefully with a vernier calliper. Make sure you lubricate the frame (unless they're carbon fibre) before insertion or you'll struggle to get it out again.

KS Dropzone Adjustable Seat Post & Integrated Lever 4.8 5 5 5

A real game changer I have had a chance to use this post on all of my local trails over the last 3 months and the operation has, so far, been flawless. For trails where I traditionally stopped to lower and then raise the saddle, the ability to do so, on the move, with no loss of flow, is just fantastic. In addition, most local descents have some short flat sections so it is good to pop the seat back up, pedal through the section and then drop it again for the rest of the descent. For other trails where the technical sections were too short to normally bother with lowering the saddle, the drop post has added confidence to each section and has opened up some new lines. The lever operation is proving to be fairly effective although it does require a short section at the top and bottom of any trail when it is safe to take a hand off the handlebars. I have faced a couple of situations where that is just not possible so a remote will always have a slight advantage, if your frame can easily accommodate the cables and you don't mind the additional clutter. The single bolt seat clamp has needed a complete clean and regrease on a couple of occasions to eliminate creaking sounds. Perhaps I didn't apply enough grease when I fitted it. I seems to be working quite well now, although I would have preferred a 2 bolt clamp. Overall, I can't see myself ever wanting to go back to a rigid post ever again! 27 May 2013

excellent bit of kit - does what it should and puts up with misstreatment 11 March 2013

it works perfectly This is great! It is way cheaper than the cable actuated models and lighter too. It's smooth, reliable and so far it works perfectly. It is slightly more difficult to actuate it than the handle bar models. It looks a little like you are scratching yourself, but hey, it is much cheaper! I can't think of anything wrong with it. I'd definitely go for the longest travel one, the one I got is 125 mm, and that is just fine travel length for me. I'm 178 cm tall. 26 November 2012

Excellent Only really bought one as i've now got a carbon frame and was concerned about puting my seat up and down a million times when on trails I wish i'd bought one sooner the amout of times i've had to get off the bike to adjust the seat when decending or climbing This takes second to adjust your seat to what ever height so easy to use no cables to route, no clutter on the bars One if not the best upgrade to get 05 November 2012

I have 2 bikes with 30.9 and 31.46tubes. Can I get a spacer to make this post fit both?

I guess the i7 would work with a spacer but it is just too expensive, only 100mm travel and probably not as strong being such narrow diameter. Thanks

Answer:

You can purchase the 30.9mm version for the smaller of the bikes and then use a seat post shim to space the post up to a 31.6mm tube. We do not currently stock a seat post shim for 30.9mm posts though unfortunately.

Can the KS i900L use the remote kit?

I am thinking about buying a KS i900 seat post but i think i want to try one without the remote first. Mainly i think the little leaver under the seat will be easy to access allowing me to alter it on the move anyway. But if the remote kit is purchased will this be able to work on the i900L?
