There are loads of dropper posts on the market - some features you need and some you don't. Which length, which drop - will it fit my bike? This can get really confusing if you are looking at new dropper post for your bike.

OneUp has made new dropper post process a lot easier. Firstly the simple design is reliable and with a user replaceable cartridge (and economically priced) means you'll get a lot of life from the post.

Secondly it's available in all the popular sizes plus it can be shimmed down by 10mm or 20mm - and its very easy to do at home. Thirdly the price is super competitive, it's a high end post loaded with features, durable and is priced competitively.
