Brand-X Ascend XL Dropper Seatpost (170 & 200mm)Brand-X's Ascend Dropper Seatpost was so good they decided to super-size it: the Ascend XL Dropper Seatpost offers longer travel for the long-legged rider or for those who prefer a greater scope of adjustment. Operated easily via a paddle style remote, this aluminium dropper seatpost lets the rider customise their saddle height for the trail ahead. The Ascend Dropper Seatpost set the benchmark for reliability and performance at an excellent price point, a proud tradition that the Ascend XL Dropper Seatpost will carry on.Ergonomic Dropper SeatpostThis Brand-X Ascend Dropper Seatpost features an ergonomic remote lever that has been designed to run from where your front shifter normally sits. Ideally suited for those running a 1x chainring transmission without a front derailleur. However, a paddle style shifter is available aftermarket for those who want to use the Ascend XL Dropper Seatpost with a front derailleur and shifter.Consistent PerformanceThe seatpost is cable actuated at the bottom of the post via a linkage mechanism which eliminates cable pull/movement, to ensure consistent performance time and time again.Features: Material: T651-7075 Aluminium Finish: Sand Blasted and Hard Anodised Black Bar mounted paddle style remote lever and cable operated internal routing Linkage mechanism eliminates any outer cable pull Zero offset, one-piece head/upper shaft with micro adjust clamping mechanism Only compatible with internally routed bikes Diameter: 30.9mm or 31.6mm Travel: 170mm or 200mm Length: 170mm: 499mm; 200mm: 559mm Cable Length: 1.5m 2 Year Warranty Rider Weight: Min: 50-55kg; Max: 120kg Weight: 170mm: 638g; 200mm: 685gMinimum Insertion Length Information: Size Minimum Insertion Length Minimum Insertion Length including the actuator (mm) 31.6mm x 499mm 170mm 120 154 30.9mm x 499mm 170mm 120 154 31.6mm x 559mm 200mm 150 184 30.9mm x 559mm 200mm 150 184 Service Guide Information:Click here to view the Brand-X Internal Dropper Post 150, 170, 200 Service Guide.Installation Guide Information:Click here to view the Brand-X Ascend Internal Route Post Installation Guide.Buy Brand-X Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
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. With 0mm and 20mm setback options it’s possible for nearly any rider to achieve the perfect fit and the clamp works with all saddle rail types.

The Masterpiece is over 40% stronger on ultimate strength tests than the strongest production seatposts on the market. Masterpiece posts weigh approximately 40g less than the same size Elite post. This weight reduction is accomplished while maintaining the strength and durability expected of a Thomson seatpost. Thomson accomplishes this weight reduction by machining the seatpost all over, including the oval inner diameter. It is able to hold closer tolerances by machining than by extrusion alone. Machining over an already beautiful design makes the Masterpiece Seatpost a work of art.Machined 7000 series Aluminium41mm seat rail grip lengthTilt adjustment from -5° to +29°Low profile clampsAvailable in 27.2mm, 30.9mm and 31.6mm diametersCertified to: EN 14766 2006 MTBThe tube and head of the Thomson Masterpiece seatpost is integral machined from one piece of high strength 7000 series aluminium. The head is not pressed or bonded in, allowing for superior strength and minimum weight. We have a long 1.614 inch (41mm) seat rail grip length. This helps prevent seat rail bending from impact loads. Most other seatposts have grip lengths of at least 0.5 inches shorter than our grip length.The Thomson Masterpiece seatpost design incorporates a bending fuse to prevent catastrophic failure. All competitive seatposts we tested failed catastrophically with the seat and clamp components, sometimes pieces of the tube and head flew off in all directions.The Thomson Masterpiece seatpost has a clamp, head, and upper tube strong enough to withstand 325 foot-lbs of torque. The tube will start to yield and bend at the seat tube clamp at about 230 foot-lbs of torque. Under severe impact the Thomson Masterpiece seatpost will bend slightly but allow the rider to come to a stop or continue the ride.The Masterpiece seatpost has all parts captive and can easily be attached to a seat without dis-assembly. Very low profile clamps means no seat interference as the swivel nuts are down between the seat rails. The designs and materials have passed extensive life and ultimate strength tests. Our ongoing testing program ensures that every production lot of seatposts meets Thomson standards.
