We have a few dropper posts in the garage so we did a little comparison on them. Dropper posts have been around for about 20 years with the original Hite Rite product sold many decades ago.
The concept is make a seatpost that fully extends during climbs for proper leg extension and allow it to drop down during descending while the rider keeps riding on the bike. This allows the rider to lower the center of gravity and use the body to move around the bike to center it to maintain balance and traction. And since the rider does not need to get off the bike (twice each time), the rider is able to maintain flow and momentum which is critical in difficult sections of the trail. Though simple, execution is very difficult as the seatpost bears most of the load of the rider and takes a lot of stress specially in technical riding.
This year, the space has heated up as companies with intensive R&D have joined the category. Check our round up of dropper posts and let us know what you think.
The posts in the line-up are:
