Is your dropper post on your bike starting to get a bit slow and sticky? You've come to the right place for a simple resolution! 

How to Keep Your Dropper Post in Top Shape 

Dropper posts transformed the mountain bike game, and in my opinion have been one of the best inventions for the industry! Saying this, they do undergo constant abuse: mud, grit, water, and relentless movement. Even the best dropper posts can fail if neglected. Though, a little care goes a long way toward keeping them running smoothly for the long haul. 

Why Your Dropper Post Needs Love 

A dropper post works like suspension, it’s full of moving parts, seals, and internal components that need attention to stay functional. Routine cleaning and lubrication help prevent wear and extend your post’s lifespan. Even a quick wipe-down after a ride makes a big difference. I tend to use the Muc-Off Suspension Serum to help keep things lubed.

Post-Ride Maintenance (cleaning and lubrication)

Step 1: Extend the post by the lever. Rinse off any dirt with water after every ride, but steer clear of pressure washers as the seals don't particularly like these. Wipe with a dry cloth.

Step 2: Lube the Seal. Apply a small amount of suspension lube to the cleaned seal to keep it actuating smoothly. 

 

Top maintenance Tips:

1/ Skip De-greasers

De-greasers strip the factory grease from seals, which can shorten their life. Stick with gentle cleaners such as the Muc-Off Nano Tech Bike Cleaner 1L.

2/ Periodic Maintenance (I usually do this every 1.5-2 months)

Many dropper posts have a removable seat collar, giving you access to the wiper seal. You can un-screw this anti-clockwise, though it can sometimes be a bit tight to unscrew at first. Clean and lube it with some SRAM Grease to keep everything in working order. This is what I use on my OneUp and Brand-X posts.

3/ Check the Actuator 

The actuator at the base of your post needs attention, too. Remove the dropper occasionally, the following advice can help you do this yourself (feel skilled)- 

"Loosen the seat clamp and gently slide the dropper post out of the seat tube while simultaneously guiding the cable housing at the front of the frame. Move both at the same pace to avoid tension. Be mindful of the housing catching inside the frame - don’t force it, as this could cause damage"

Clean the actuator, and re-apply lube to keep it smooth. While you’re at it, check for air pressure loss (check if your dropper has this function), usually situation at the top of the dropper under the saddle, and replace the inner cable if it’s worn. I would use the Shimano MTB Stainless Steel Gear Cable Set.

 

Common 'Concerns'

1/ Can I clamp my bike by the dropper post? 

You can, but only when the post is fully extended. Use a soft, clean cloth between the clamp and the shaft to avoid scratches. 

2/ What’s the best way to store my bike? 

Always store it with the dropper post fully extended. Storing it in the down position puts unnecessary stress on the seals, which can lead to failure over time. 

3/ Is it OK to pick up my bike by the saddle? 

Avoid lifting the bike by the saddle when the post is NOT extended. Doing so can damage the internal seals and lead to a “spongy” post that needs servicing. This happens a lot with Rockshox Reverbs. 

 

Summary

Your dropper post is a hardworking part of your bike, but it can last for years if you take care of it. Keep it clean, lubricated, and stored properly, and it’ll repay you with reliable performance on every ride. A little effort now saves you time, money, and frustration down the trail.
