Remember riding your bike before clip-less pedals? Before suspension even existed? How about before disk brakes? Would you want to go back to any of that? Well that's how everybody feels about suspension seat posts.

The ability to raise and lower your seat on the fly not only allows for the best possible performance but also offers extra safety while riding. Being able to drop your seat before a technical decent could be the difference between cleaning the section or picking your teeth out of the dirt. that's why at X-Fusion we knew we had to make an adjustable seat post dubbed The Hilo.

The Hilo hydraulically adjusts anywhere within its 100mm of travel using either a cable actuated handle bar remote or simplistic lever design under the seat. The Hilo post will change the way you ride your bike.


Adjustments height seatposts are improving the way that mountain bikers ride everywhere. All riders can benefit from moving the seat down for added stability on descents or increasing the seat height for climbing.

X-Fusion has been manufacturing hydraulic systems for over 10 years so it was natural for us to jump into this emerging product segment. Our goal is to create the most durable, most reliable adjustable height seatpost on the market.

  • Hydraulic design allows for smooth adjustability
  • Double key-way design prevents lateral twisting
  • Passes CEN testing for fatigue and impact
  • Wide range of seatpost angle adjustment
  • Easily convertible from lever-actuation to remote handlebar actuation or vice-versa (with aftermarket kit)
  • Lightweight design 1.3 lbs (0.6 kg)


Travel: 100mm
Weight: 620g
OD: 27.2 / 30.9 / 31.6 mm
Options :

  • Seat Post Angle
  • Adjustable
  • Travel
  • Adjustable
  • Remote Control

Over all length:

  • 425mm (125mm travel)

Riders with skinny 27.2mm seatposts will be pleased to see the X-Fusion's compatibility stretching beyond the usual 30.9 and 31.6mm variants.
Those same people will also be pleased to see the price - the Hilo is the cheapest dropper post in our test.

A few of our testers tried out the remote and actually ended up back with the seat lever - the lever remains reliably light but positive to use.
..this is a great, cheap way to get infinitely adjustable seat drop.

You're reviewing: X-Fusion Hilo Seatpost 125mm

X-Fusion is focused on a simple concept: build high quality, all metal suspension systems that provide a higher level of performance and durability. Take a look at our Velvet forks for example. Inside the Velvet RL you will see a fully-adjustable CNC’ed-machined damping cartridge, lightweight full-air spring system, as well as all aluminum knobs and adjusters. And it’s not just the Velvet forks that get this kind of treatment. From the Vengeance to the O2 shock line to the Hilo dropper post, there is no denying the attention to detail and the focus on quality.

The X-Fusion brand was started in 1999, but the company had been manufacturing suspension products for at least 10 years prior to that. With a 20-year history in suspension, it’s no surprise the level of attention provided to every detail. In the past 5 years, we have greatly expanded our product line, established a global support network and made huge gains in overall market share. Just ask companies like Cannondale, Specialized, Ibis, Jamis, GT and others. These brands rely on X-Fusion to provide the highest levels of performance possible.
