KINEKT XR Bike Suspension Seatpost, Aluminum 34.9mm-XR

The Kinekt XR Aluminum Suspension Seatpost is engineered to support riders weighing between 80–320 lbs (36–145 kg), making it the go-to choice for e-bike riders, cargo bike riders, and anyone looking for maximum support and comfort on variable terrain. With its robust aluminum construction and firmer spring setup, the XR keeps you planted and comfortable—absorbing bumps, chatter, and vibration so you can ride longer with less fatigue.

Like all Kinekt seatposts, the XR is easy to install and features a quick and easy preload adjuster knob, so you can dial in your suspension feel mid-ride. It also comes with a range of interchangeable springs, allowing you to match your setup to your body weight, cargo load, and riding preferences.

The XR is especially well-suited for e-bike riders, whose upright position and in-saddle style of riding benefit from this seatpost’s increased support and stability.

• • COMFORT IN MOTION - Feel the smooth difference of Kinekt Seatpost as it floats over any terrain or road surface, absorbing more shock, providing better control, and less fatigue. Kinekt’s adjustable active suspension springs are made to match your weight and riding style to get you back in the saddle and on the trail, road, beach or mountain without delay.
  • FIND YOUR SEAT POST: 【STEP 1】RIDER WEIGHT - LR if you weigh 80-180 lbs. (36-82 kg) or XR if you weigh 180-320 lbs. (82-145 kg).
  • 【STEP 2】 DIAMETER - Find the measurement printed on your current seat post or look up the spec for your bike and model on-line.
  • 【STEP 3】 LENGTH - You need at least 40mm between seat rails and top of seat tube for proper fit. Find the length printed on your current stem or look up on-line.
  • BIKE TYPE - If you are choosing a Kinekt suspension seatpost for an e-bike, we recommend choosing the LR for riders under 150lbs (68kg) and going with the XR for riders over 150lbs, this accommodates the in-saddle riding style and weight distribution that e-bikes produce.
