The Forca dropper seatpost is a low tech mechanical adjustable seatpost. While you may want to cringe at the thought of a spring and pin operated mechanism between the legs, the Forca is a solid offering and features benefits over hydraulic or air operated systems.<\/p>\n

What is the Forca SPS-400?<\/h2>\n

Forca is based in Bruchsal, Germany and, other than adjustable seatposts for mountain bikes, they also produce electric scooters.<\/p>\n

When I first saw the Forca SPS-400, I thought it was simply a TMARS dropper post clone. A closer look, and some assurance from Cycle Factory, revealed that Forca have made some changes and improvements to their iteration of this seatpost design.<\/p>\n

The Forca SPS-400 features 110mm of adjustment with 3 height positions. There are options for both 27.2 and 31.6mm seatposts. The SPS-400 comes in at a claimed weight of 520 grams.<\/p>\n

A big tick in the Forca’s favour is the price. It retails for R1,950.<\/p>\n

Rejoice: 27.2mm seatpost sizing<\/h2>\n

A little side note, my Contraband Rogue has a 27.2mm seatpost. Unfortunately, adjustable seatposts for this size are tricky to come by. This is due in it being a less common sizing and that the smaller circumference makes it harder for manufacturers to squeeze everything inside the post. Through local channels, I am only aware of the KS Lev and Thomson Elite. Not spoilt for choice. For this reason, it\u2019s good to see another option for the 27.2mm crowd.<\/p>\n

How does this mechanical dropper post work?<\/h2>\n

The Forca employs a simple spring and pin mechanism. A steel pin is actuated by a cable connected to a lever on the handle bar. There are three positions (holes) on the post which the pin can slot into and fix the post in position. Two bushings assist with the smooth raising and lowering of the seatpost. Should you want added protection, as the holes in the post are exposed, the Forca comes with a very 90\u2019s rubber booty which fits around the seatpost and helps to prevent dirt from entering the system. Pressing the lever and applying some weight depresses the post. Lifting the post also requires some weight to safely unlock the spring that raises the post.<\/p>\n

Forca claim that this simple mechanical design makes the SPS-400 extremely rugged and, should anything go wrong, easy and very affordable to repair compared to more complex hydraulic and air dropper posts. As the spring is rated for 10 million cycles, it is likely that the part mostly likely of ever wearing out are the two bushings (especially if you allow mud to gather in the post). Cycle Factory say that replacement parts will be readily available.<\/p>\n<\/p>\n
