As far as alloy seatposts go, Genetic has kept things simple with the STV. If you’re looking for an affordable, easy-to-fit option with subtle style, this could be one of the best mountain bike seatposts currently available.
Genetic STV Seatpost - Technical details
The Genetic STV Seatpost is an alloy seatpost, suitable for road- and off-road riding. The shaft is made of 7075 CNC butted alloy, with a two-bolt micro-adjust full cradle system.
Genetic says the seat clamp system avoids applying stress riser points onto the saddle rails unlike the “scissor-action” of some other two-bolt-type design seat clamps. The clamp fits all standard 7mm saddle rails, including ovalized carbon.
The seatpost has a 0-degree setback and is available in 27.2 (tested), 30.9 and 31.6mm diameters, each of which measures in at 350mm long. The STV has black graphics and matching black anodised bolts and weighs around 245g.
Genetic STV Seatpost - Performance
The Genetic STV seatpost doesn’t claim to revolutionise your ride experience - it’s a rather basic, inline seatpost that does what it’s meant to; it holds up the saddle.
Installing the seatpost was simple. I applied a small amount of grease before slotting it into the seat tube and tightening the clamp. Once the seatpost was in place, I fitted my saddle onto the seat clamps.
Two-bolt seat clamps can be a pain to adjust, but I found this one easy. The bolts were great quality, making it easy to loosen them. Fitting the saddle onto the rails, and then tightening them back up was easy as well. The final thing left was adjusting the saddle height. To help with that Genetic has added markers to the back of the post. It doesn’t tell you the seat height but does help for future reference, as you don’t have to mark your saddle height with tape or marker.
Genetic STV Seatpost - Verdict
Overall, the Genetic STV seatpost is a great quality, budget seatpost. It is alloy, so you’re unlikely to gain much comfort from it but it does have really neat looks and comes with quality bolts. The seat clamp is definitely sturdy and won’t damage your saddle rails. The seatpost comes in a variety of diameters, which is a perk, but there is a chance that the 350mm might not be long enough for some taller riders, especially if you have a very sloped top tube.
Price-wise, this one comes in at £40 which is pretty good for an alloy inline seatpost. For comparison, the Zipp Service Course Alloy Seatpost retails for £56, and the Pro LT 6061 Alloy In-Line Seatpost is £50.
Overall, the Genetic STV seatpost is a great option if you’re looking for a good value, quality in-line seatpost.
