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 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.

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!
