Ritchey's Classic Post showcases a cool high-polish silver finish that looks good on any bike, modern or retro. The proven 2-bolt design gives you balance between a vise-like grip, strength, weight and adjustability. The low-profile clamp reduces stress on lightweight rails and uses bolts that are oriented to the axis of the rails for greatest contact area with your saddle.

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.

The KS LEV DX Dropper Seatpost is a more cost effective version of the LEV that sacrifices none of the legendary performance. While it gives up the flashier actuator lever, the remainder is essentially the same, making it a perfect option for those who can deal with a few added grams when it keeps a few dollars in their pockets. The LEV is prized for, among other things, the fixed cable box at the lower collar. The upshot is that you achieve a fixed cable position, which simplifies cable routing, and reduces the chance of your cable loop getting caught up in your suspension linkage. Further aiding the cable routing, you’re able to adjust the orientation of the cable box independently of the post’s rotation. This routing method is more user friendly than the stealth routing that’s become popular, while also being compatible with a number of frames that simply don’t allow for stealth routing in the first place. One of the immediately recognizable traits of the LEV is that the saddle is fixed in place, unlike many other posts that have a small degree of play out of the box. This is because the LEV is held in place by a one-way roller bearing, which clamps the inner post tight. Atop the inner-post, you’ll find a micro-adjust, zero-offset head allows for perfect saddle setup. Among the well-considered details that set the LEV apart, one of our favorites is the handlebar mounted remote. Unassuming as it may be, this miniscule engineering marvel feels great in the hand, and is a snap to operate. It’s designed to stand in place of the inner clamp on an ODI lock-on grip, should you choose. The DX forgoes the hinged clamp and carbon lever on the LEV in favor of an aluminum version, but like its composite sibling, it isn’t adorned with the sharp edges that can turn other actuator levers into flesh-hungry blades in the event of a crash.

The name says it all: Thomson's Masterpiece Seatpost combines the best materials, exceptional strength, perfect function, light weight and the classic beauty of all Thomson products. All Masterpiece posts are extruded and then painstakingly machined from a single block of ultra-strong 7000-series aluminum, and they all weigh less than 200 grams complete. This means you get a post tough enough for any ride on or off road and at a nice and light weight that will complement your dream bike. What's more, you get Thomson's easy-to-adjust and super reliable 2-bolt seat clamp that makes it a breeze to dial in your perfect seat position from minus 5 degrees to plus 29 degrees.

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

The Cascade dropper post pays homage to the Cascade mountain range, home to some of the best riding in the PNW. This post is a workhorse: it’s super reliable, loved by our customers, and now features multiple travel options. The Cascade provides dependable up and down service for the miles to come, and maintenance on the Cascade is easy (like all our droppers). Plus, external routing at the mid-cap ensures your cables are kept nice and tidy during up and down actuation. You can find sweet upgrades to the Cascade’s OG dropper design on the posts featuring 150/170mm of travel. These models have larger diameter stanchions, making them stiffer and lighter… which is sweet because who wants a bike part that’s heavy and too compliant? These longer travel models also come with an added DU bushing to combat seat wobble, because let's face it… the only thing that should be wobbly on your bike are your legs after a long ride. Levers: - Choose from our Loam Lever, Puget 1x or 2x drivetrain compatible levers, or Roadie/Drop Bar Lever Kit for road bars - 1x Lever - Designed to be used with bikes using a single front chainring, this is a "shifter style" lever - 2x lever - Designed to play nice with front shifters, this is a "vertical" lever that accommodates for the shifter on the left side of your handlebar Product Specs: - Choose any lever kit - 30.9 & 31.6mm Diameters - Weights: 125mm - 608g, 150mm - 613g, 170mm - 674g - 2-bolt Micro Adjust Head - Fixed External Routing at the Mid Cap for clean cable routing - 3-year warranty!

Why should burly bikes have all the fun? We asked that question when we released our first 27.2 dropper post. The Pine continues the tradition of bringing great, reliable dropper posts to bikes with skinnier tubes, whether it be your classic hardtail, XC bike, gravel grinder or cyclocross rig. All-new versions of the Pine now come with the option of 90 and 110mm of travel. This accommodates more bikes and helps you win the battle against getting bucked forward by your seat on steep and techy terrain. And while extra travel is always a great perk, we think the best addition to the new models is a slick 1-piece alloy stanchion, which drops a whopping 100g of weight from the older models. To keep descending even more distraction free, the Pine features external routing at the midcap rather than the post head, allowing you to keep your cable routing nice and tidy. - Travel: 90mm or 110mm - Post Diameter: 27.2mm - Weights: 90mm - 490g, 110mm - 530g - Infinite Adjust: So you can pick from multiple positions - 1-piece alloy stanchion (no more press-on head) - External cable routing with fixed cable entry at the mid cap - Lever sold separately - 3-year warranty!

The Coast dropper is the world's first Suspension Dropper Post, combining ride-smoothing suspension and the benefits of a dropper into one seatpost. This dropper is designed to help riders on all types of bikes, from packed up trekkers, to the cross-country wanderers, even the weekday commuters. We developed the Coast because the earth isn't flat (no matter what those people on Twitter say)—it's kind of bumpy. And, while we all like coasting along on freshly paved roads, mountain paths are enticing, and potholes exist no matter how much we swear at them. The Coast Post was designed to soak up some of these vibrations. We accomplished this via 40mm of tunable air suspension housed in the internals to make your ride a bit smoother. While this post provides some relief from everyday chatter, it also comes with up to 120mm of drop. Most people associate dropper posts with mountain biking, but it turns out they're pretty jazzy on everything, from gravel bikes to trekking rigs and commuters. Let's face it, when your saddle is at the proper height for riding, dismounts can be…inelegant. A dropper post allows you to push a button and be in a flat-footed position when you want, easily returning you to the best saddle height for riding once you get going again. This can be great for starting and stopping in city traffic or getting on and off a bike packed up with stuff—or really, if your hips are just extra tight and creaky like ours. Plus when you're going downhill, a dropper easily gets the distraction of your seat out of the way, letting you lower your center of gravity. Not only does this put you in a safer riding position, it also makes descents more fun (we wish this safer-but-also-more-fun combo was true for more things in life). - Air Suspension: 40mm - Weights: 31.6/30.9 External routing - 615g, 31.6/30.9 Internal routing - 610g, 27.2 External routing - 540g, 27.2 Internal routing - 535g - Cable Routing: Internal - Cartridge: 2-chamber hydraulic and adjustable air - Lever sold separately - 3-year warranty - Perfect for commuters, gravel bikes, or hardtail bikes - NOTE: This is NOT a replacement for rear suspension, it is a suspension seat post which helps absorb the larger bumps while seated. It does not provide small bump compliance found in rear suspension mountain bikes.
