[Closed] Home made dropper post.

After seeing someone attempt it on a thread on reddit I thought I'd give it a bash myself. ([url= http://maxengineeringdesign.blogspot.co.uk/2014/09/simple-dropper-post.html ]As usual there is blog spam that I've written on the matter[/url])

Used a gas strut in-between two clamps that I had made up that work like a quill stem.

Threaded one of the bolts to take the thinner end of the gas strut and the other end has a dome eyelet to sit in the head of the other bolt. A 150N gas strut provides ample force, others I have seen use an 80N but I suspect once its taken out in the mud it would clog up a little bit, so went for nearly double the force.

Will end up at ~£50 once the seat post clamp has been bought (assuming £25 for a QR clamp) which is a lot cheaper than the alternatives. I admit that having to undo the QR is a pain whilst moving but at the price its minor really.

Also not too happy about the seat post and seat tube wearing against each other but if its well greased I don't see a major issue as this bike doesn't have a huge amount of mileage put through it.

What do you think?
