What is a dropper and which one do I need?

Ever since I first used a dropper seat post I have been convinced that it can be one of the most, if not the most, effective upgrades you can make to a mountain bike. The simple addition of a dropper seat post makes you a better rider.

It’s hard to deny that the dropper seat post has been a true game-changer in modern mountain biking and trail riding. This ingenious innovation pioneered by KS has revolutionized the way we ride. It allows us to ascend with ease while keeping our seats at the perfect height, and when it’s time to let loose and tackle that thrilling descent, the dropper seat post effortlessly moves out of the way.

It’s a old video but provides a great explanation of what a dropper is a how to use it.

External or Integrated Dropper

Ultimately your bike frame and compatibility will determine which type you need. The majority of dropper post cables can be internally routed. This requires a hole in the frame (usually somewhere low down on the back of the seat tube) to route the cable up through the seat tube to the bottom of the seatpost. The other cable option is an external cable that either attaches at the dropper post’s collar or up at the head where the saddle attaches.

The benefits of an internally routed cable include clean looks, better protection from dirt and debris, and zero cable movement when dropping the post.

The upsides to an externally routed cable are compatibility with any frame and a simpler setup. The negatives deal primarily with cables that attach to the seatpost head, because the cable can interfere with the bike’s rear tyre or hit your leg if not routed carefully.

The final option does away with the cable completely – the RockShox Reverb AXS or the brand new wireless dropper from KS both use a wireless electronic system. No cables required at all and also enabling you to swap the post from bike to bike.

KS Dropper Options – E, Rage & LEV

With each of these models you can choose the seat post diameter required to fit your frame and then the amount of travel you require. The amount of travel you can achieve may be determined by the length of your seat tube as the longer the travel, the longer the overall length of the seatpost.

And Finally, Levers or Remotes…

A 1x gear system on a flat handlebar bike frees up the left hand side of your handlebar to allow space for your dropper remote to sit. A southpaw or Westy 2 are the most popular options. If you are running a 2x bike then the KG vertical remote will work best as is doesn’t interfere with gear shifters. And finally for drop bar gravel bikes the KG Drop option is perfect.
