Seatposts

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored seatpost color is available on the Zipp Service Course Seatpost. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering, we are proud to offer redesigned Service Course seatposts. - Material: 6061 aluminum - 2-bolt adjustability - Minimum insertion length: 90mm

A reliable dropper seatpost with a 3-key chassis design that minimizes shaft play for a post that provides smooth and consistent travel adjustment. Get up to get down  The Bontrager Line 34.9 dropper seatpost offers reliable and infinite adjustability within multiple dropping ranges to suit riders of all types. A 3-keyed chassis design provides additional lateral rigidity and minimizes play while a 2-bolt rocker head is perfect for fine-tuning saddle tilt. Line 34.9 is also designed with a shorter overall length, which allows more adjustability and frame compatibility. Need an even shorter drop? Grab a 10mm or 30mm travel reducer spacer. PRODUCT DETAILS - Air-sprung hydraulic locking cartridge offers infinite adjustability within dropping range - 3-key chassis prevents rotation for a stable ride - 2-bolt rocker head with micro adjustment allows for easy saddle tilt adjustment - Shorter overall length [versus previous version] allows more adjustability and compatibility - Fine-tune your fit fast and easy with 10mm and 30mm travel reducer spacers - Lever sold separately. Compatible with Universal Lever, Under Bar Lever, and Elite Under Bar Lever - Internal cable routing keeps housing tucked away and free from moving wheel - Frame must be compatible with internally routed seatpost routing

The carbon Service Course SL seatpost is specifically tuned to be more shock absorbing than the "comfort" seatposts on the market, while still passing our strict internal MTB strength test. Flex engineered into the lightweight carbon tube keeps the rider comfortable over any terrain. Better fit means better performance, and if your saddle is out of position, you'll waste energy with every pedal stroke. The secure, two-bolt clamp makes for easy micro-adjustments of saddle position, and the head has been redesigned for maximum bolt-head accessibility. The Service Course SL seatpost makes it possible for nearly any rider to achieve the perfect fit, and the clamp works with all saddle rail types. - Distinctive Zipp cosmetics - Unidirectional Carbon fiber tuned for ride comfort - Lightweight clamping system - Lifetime warranty

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.

Kinekt suspension seat posts are the best in the biz and will make your JackRabbit ride as smooth as butter. Upgrade your JackRabbit with this seat post for a game-changing shock-absorber effect. Please note: this is a seat post and does not include a seat. We worked with the fine folks at Kinekt to create this seat post package designed specifically for JackRabbits. This seat post can support riders who weigh from 80-320lbs (36-145kg) and for taller riders from 5'2" to 6'6" (versus the 4'10" to 6'2" range of our stock seat post). The diameter of this seat post is 27.2mm (the same as our stock seat post) and the length is 350mm. This makes the seat able to go higher than our normal seat, which is useful when sitting on the Kinekt because the suspension causes the seat to lower when body weight is applied to it. This product is compatible with the following bikes: - JackRabbit OG - JackRabbit XG - JackRabbit OG2 - JackRabbit OG2 Pro - JackRabbit XG Pro - JackRabbit MG Renegade

For over a decade, FOX has led the way in dropper post innovation. The latest iteration, the Transfer Neo, takes it even further with a longer drop, lower stack height, greater tire clearance, and faster actuation, all powered by the new Neo wireless protocol. The Neo wireless system is designed to be over 100x faster than Bluetooth, delivering near-instantaneous response with virtually zero latency. Coupled with the 2025 Transfer’s incredibly robust internal sealing design, adjustability, and proven durability, Transfer Neo truly rises above. - Fastest actuating wireless dropper on the market, and ultra-low latency makes micro-adjusting your seat height to suit varying terrain super precise - 47mm stack height (only 11mm more than a standard Transfer) and optimized battery placement for better tire clearance - FOX-specific battery provides 30 to 40 hours of battery life, depending on frequency of dropper post actuation, with 1.25 hr to 1.5 hr charge time using the included dock and USB-A to USB-C cable - Fully supported by the FOX Bike app. Riders can quicky access an overview of Transfer Neo components, download firmware updates, and activate useful features like Bike Park Mode, Transport Mode, and monitor service interval tracking - Wireless lever is designed to be as familiar a feeling as possible. A rubber-coated thumb pad mimics the texture and distance from the handlebar of a regular Transfer lever, but with a shorter, 6x lever throw reduction for smoother operation - Lever features pairing buttons and LED indicator, utilizing a CR2032 battery with a 12-month life and tool-free replacement - Standard 22.2mm, Matchmaker and I-Spec EV clamping options included with post - Schrader valve on the top of the post, making for easy pressure adjustments to suit terrain or rider preference, or to compensate for pressure loss over time - Transfer Neo has the same sleek new head design as the mechanical Transfer, providing ultra-low stack and bullet-proof 2-bolt security and infinite angle adjustment

Now travel adjustable in 5mm increments and available up to 240mm of drop. The best-of-the-best technology is available in the Factory Series models, featuring buttery smooth, ultra durable Genuine Kashima Coat. - Fully redesigned hydraulics of the 2025 Transfer feature an entirely new sealing system for enhanced durability. The full-service interval is now at 300 hours, which most riders can do with the tools in their garage - Metal-backed EKONOL (PTFE/Teflon) bushings to achieve tight tolerances and the lowest possible friction to allow easier actuation - The placement of the new air chamber allows riders to recharge and adjust air pressure through a Schrader valve under the seat clamps. Tune to your preferred return speed or adjust for environmental factors such as altitude or ambient air temperature. A metal valve cap with O-ring (the same we use on FOX suspension) ensures zero air leaks through the valve - Low stack height and 2-bolt clamp design that riders loved from the previous Transfer, while improving aesthetics and keeping weight to a minimum - Wider range of options, with up to 240mm of drop, and adjustable travel (up to 25mm in 5mm increments) - Cable actuated with tool-free quick disconnect for easier installation and removal, low lever force provides consistent actuation pressure even with saddle weighted or unweighted - Remote lever sold separately
