How to fit a dropper seat post

Dropper seatposts are a much-needed upgrade to any bike. These nifty gadgets improve your skills and will see you safely stay on top of your saddle for longer. We were sent a Lyne Components 27.2mm dropper post to test and we had it fitted at Knipe Racing in Durbanville.

Master mechanic and shop owner, Louis-Bresler Knipe did the fitment, and this is what went down.

I ride a 2018 Giant Anthem Advanced Pro 1 and it is one of the very few bikes still running a 27.2mm seatpost. After falling in love with my previous bike’s dropper, I can’t see myself riding without one.

Shop owner and master-mechanic Louis-Bresler Knipe working his magic. First to be removed was the crank and BB.
With the BB removed it is easier to access the frame








  • First of all, Louis applied some tape to my saddle from which he took accurate measurements to confirm the height and reach of my standard seatpost. The bike was then clamped and the first thing to be removed was the crank and BB.
  • With the internally routed Lyne dropper, Louis started feeding the internal routing feeder through the top of the frame directing it carefully to the BB opening.

Let the cable feeding begin








  • The standard carbon Giant seatpost was removed and the new dropper cable was fed through the top of the exposed seat tube. Some much needed high-quality carbon paste was applied to stop the seatpost from slipping.
Success! No to attach the Lyne dropper
Would you look at that!







  • The dropper’s cable was attached and the excess removed. Lyne supplies two separate levers with their product which makes fitment even easier. Because I am running a dual remote lock-out for my suspension, I opted for the 2x lever. The lever is small and unobtrusive and blended in seamlessly with the rest of my cockpit. The design of the actual lever made for a sleek and uncluttered handlebar – WINNING!

Almost ready…







  • The seatpost and saddle were adjusted to my specific length and reach. Louis reattached the crank arms and BB and once again lubed the entire drivetrain.

The new dropper lever
  • The much-needed test ride saw Louis return a couple of minutes later, while being visibly chuffed with his work.


  • An hour or so later, my bike was lubed and now fitted with a brand new 105mm internal dropper seatpost. For the weight conscious:  the Anthem weighed 11.32kg (large frame, including sealant, bottlecage and pedals) before the dropper was fitted. After the installation the total weight was 11.72kg. Considering the size of the bike and the heavier tyres used, that is a decent weight to slog around the mountains.



The final product! Stoked
