Mass is the enemy of performance, so we pulled out all the stops to make the Alpinist Seatpost the lightest post we've ever seen that passes our standards. At 136 grams (27.2mm x 300mm), it's about as light as you'll find. Not only does light weight make for faster climbing, it also improves acceleration and ride quality. The Alpinist 2-bolt micro-adjust clamp with extended saddle cradle ensures precision fit and secure retention. Available in two sizes, 27.2mm x 300mm and 27.2mm x 360mm, each with a 12mm setback. And because they are backed by a no-fault crash replacement policy and lifetime warranty, you can rest easy knowing that we've got your back.
- 136 grams (27.2mm x 300mm),
- 2-bolt micro-adjust clamp with 46mm saddle rail cradle enables an effective offset from 0mm to 20mm.

The Terra seatpost is the best choice for riding mixed terrain, gravel, or rough roads because it smooths the ride by allowing significant vertical compliance. The secret to this ride smoothing post is in the composite layup that we utilized. By utilizing composites with varying elongation characteristics at specific locations in the post, we enabled vertical compliance for comfort while retaining requisite strength for mixed terrain riding, all at a sub-200 gram weight (27.2 x 330 x 0).
- 18mm Vertical Compliance (20mm offset / Full Extension)
- 194 grams (27.2 x 330mm x 0)
- Advanced composite construction delivers ride-smoothing vertical compliance.

The gravel around our backyard Wasatch Range inspired the idea of a dropper post for fast and technical descents. It proved to be just as useful out in the Flint Hills of Kansas as well, when pedal efficiency was demanded, but where short and steep descents proved to be just as technical. In line with the ethos that our gravel products must provide more confidence, the 40mm of drop puts riders in a more comfortable and manageable position to descend fast with more confidently.
The unique design allows for a more reliable and serviceable cartridge mechanism in a 27.2mm package. Similarly, the placement of the cartridge makes for a post that can be cut to the desired length for a potential weight loss of 50g from the initial 395g package. For bike packers, this inverted dropper allows for any saddle bag, of any size to be fit without any special brackets or attachments. Finally, with 25 degrees of saddle tilt adjustment, and shims included for 30.9mm and 31.6mm seat tubes, the G Series Dropper Seat Post is compatible with a wide variety of gravel bikes.
Additionally, the dropper post is an excellent choice for XC riders and racers looking for a lightweight short-travel dropper post solution. The dropper post is compatible with cable-actuated remote dropper levers.
Built for the lightweight modern gravel bike, the G Series Dropper Seatpost features 40mm of drop to deliver the confidence that a lower center of gravity provides on descents of any kind. The inverted design sheds mud and allows for your excess length to be trimmed off for additional weight savings. Lower to the ground gets you closer to gravel nirvana.
• 40mm of drop
• 395g, with up to 50g in cuttable weight savings
• Mechanically actuated
• Compatible with most cable-actuated dropper post remote levers
• 27.2mm Diameter
• Includes shims for 30.9mm and 31.6mm
• Fully Serviceable

Symmetry is a key component of sound design. King riders have, for years, paired our headsets with our bottom brackets and hubs, to provide a few, classy pops of color to their bikes. But that left them with no off-setting visual cue at the top of the bike to make the look more symmetrical. If this strikes you as a goofy way to think about your bike, fair enough, but it’s one of those things that bothered our eyes a little, and enough riders asked us to make a seat collar that we went ahead and designed one.
Why You Want It: Because colors make you happy. Because what we wrote above about symmetry and balance makes sense to you. Because it’s another high-quality component you can use to show your bike how much you love it. Because it just looks great.
- Aluminum collar with stainless steel bolt, washer, and barrel nut
- Available in colors to match King components
- Made in the USA
- Lifetime Warranty
- Maximum Torque is 6nm.
