How to Use a Dropper Post Effectively
A Dropper Post dramatically heightens the fun and efficiency of your ride. But it takes time to learn to use it effectively.
Unlike uniform units like minims, drops communicate a degree of approximation and individuality that the minimometer could not. This epistemic virtue can be seen in early articles experimenting with variations in drop volume.
Choosing a Dropper Post
A dropper post may be one of the most useful accessories a mountain biker can install on their bicycle, but not all of them are created equal. Choosing the right Dropper Post for your specific needs can make riding trails safer, more fun and faster.
The first step in finding the ideal Dropper Post is to figure out what size frame you have, as well as your preferred saddle height when pedaling uphill. You also need to know if your bike is compatible with internal or external cable routing, and whether you want a post that allows you to change the amount of travel it offers.
Next, determine how much of your dropper post’s shaft will fit inside of your frame’s seat tube when it is at its lowest position. This is called the Post Insertion Length, or PIL. Most brands require that the post be a certain distance below your frame’s seatpost collar and saddle rail clamp stack height (known as the usable height) in order to provide the most safety.
Once you have this information, you can start shopping around for a post that meets your needs. Make sure you’re not buying a post that is too long, as this can cause your frame to develop bends or cracks. You also don’t want to buy a post that is too short, as this can lead to improper saddle positioning on the bike and can be unsafe for your ride.
Installing a Dropper Post
There’s a reason dropper posts are so popular off-road – they make for more comfortable riding. But Dropper they’re also becoming more common on paved roads and cyclocross bikes, making them a great option for riders who want to take their skills to the next level.
Getting a dropper post set up properly can vary a bit depending on the model of the bike and how it’s installed, but there are some general steps to follow. First, determine the rider’s preferred seat height and install the post to that height. Next, install the lever where the rider can reach it comfortably and link it to the cable (housing) with zip ties. If the frame has internal cable routing, it’s best to have a professional do this part of the installation to avoid any damage to the cable or the frame.
Once everything is linked, seat the cable bushing in the actuation cradle on the bottom of the dropper post. Finally, tighten the seatpost clamp bolt to the frame’s recommended specs but no more than 6.5 Nm.
Before you ride, inspect the cable and housing for any kinks or signs of corrosion. Then, use the remote to lower the seat to test out the dropper’s travel and ensure that it works properly. Once you’re satisfied with the dropper’s functionality, re-tighten the seatpost clamp bolt.
Adjusting a Dropper Post
The most important thing to check with any dropper post is that it’s working properly. If yours is returning to full mast very slowly or not at all, it may have low air pressure. Typically, this is the easiest thing to fix – simply open up the seatpost clamp and inflate the post. Consult the manufacturer’s manual for specific recommendations (usually around 300psi) before re-tightening the bolt.
It’s also worth checking that the actuator isn’t stuffed too far into the frame. This is a common issue that can cause sluggish travel extension or weird noises.
Once you’ve checked that the post is working correctly, it’s time to set up the remote lever. The latest designs operate much like a gear shift lever, and there are several aftermarket options from manufacturers such as WolfTooth, OneUp, PRO and RockShox (to work with their respective posts).
As well as enabling a more comfortable ride by adjusting your saddle height to obtain an optimal pedalling position for climbs, dropping the post during descents can improve control and safety by allowing you to get your saddle out of the way to clear obstacles or take tight corners more easily. Practice using the post during your rides and, over time, you’ll find that it opens up a whole new world of possibilities. Good luck!
Troubleshooting a Dropper Post
Occasionally, your dropper post might develop problems that prevent it from performing properly. Depending on what the problem is, you might be able to Dropper fix it yourself, or you may need to seek help from a professional bike mechanic.
If the lever won’t stay closed, you probably need to replace the dropper post keys (part number 572184). These are easy to find and are inexpensive, but you’ll want to be careful when removing and installing them. The lever must be completely removed from the post, and you should clean any residue on the bottom of the actuator with isopropyl alcohol before reassembly. You’ll also want to replace the plastic filter retaining ring, and lube the post with Slickoleum.
Another common problem is air leakage from the internal seals. If this happens, the post will sink or feel spongy. This can be fixed by taking the post to a mechanic, who will bleed the post and restore proper operation.
Finally, the cable might be snagged or kinked somewhere, preventing it from moving through its housing when the lever is activated. This is a simple fix, and can be done by following the cable back from the lever to the post. A bit of suspension grease will also go a long way, and can be applied to the seals, guide pins, and upper and lower tube.
