Improved reliability, but still a top pull design at an average price

X-Fusion’s new dropper seatpost is a definite improvement on its previous design, but it’s not as ‘SuperLight’ as suggested. The company’s pricing is keen rather than killer when compared to its forks too. 


A switch to an alloy rather than steel shaft – plus a new clamp design – helps drop 100g from the weight of the previous Hilo 125 post. Yet at 554g with remote cable and lever it’s no lighter than the benchmark RockShox Reverb, though it’s lighter than the KS LEV and Fox DOSS posts. 

Unlike with the KS LEV, CrankBros Kronolog and internally routed Reverb Stealth, the cable coming from the very top of the post means you still have to deal with the potential paint rub/tyre catch issues caused by the loop of cable expanding as the post drops. 

Still, X-Fusion have redesigned the mechanism itself with a much better filth-protected cable and hidden clamp rather than the old ‘looped over the top‘ design. That means both units we have on test have already survived longer without seizing than previous Hilo posts, and neither is showing any significantly slower/stickier cable action. 

The new fore and aft bolt clamp with reversible lower cradle is also a lot more secure if you bounce off the saddle on a big G-out or crash than the old side bolt design was. The available 30.9mm and 31.6mm sizes will fit most bikes. 

The much-copied Maverick-style joystick slides neatly under the shifter windows of Shimano gear – on either side of the bar – for a very neat cockpit setup. Pushing the lever in any direction drops the saddle smoothly down to any point you want in the 125mm stroke.

Extension speed can be controlled easily by varying the air spring pressure, but it was only after talking to X-Fusion in the US and confirming that the shaft soft-stops 12mm short of the collar that we stopped trying to crush it all the way down. 

The double key-way design keeps any rotational twist tolerable and it still performs no worse than new even after several months of daily riding. Seals, pressure, cable and so on are all still fine even after ‘that’ UK spring, with none of the air leak or freezing-solid issues we’ve experienced on DOSS seatposts in sub-zero conditions. 

While the pricing isn’t as dramatically aggressive as X-Fusion’s fork range, it’s still significantly cheaper than Fox and RockShox options. However, it’s outgunned on value by KS posts with comparable technology.
