Kinekt Suspension seatposts are available in three versions:
LR: aluminum construction and spring specifications for riders from 80-180lbs (36-82kg)
XR: aluminum construction and spring specifications for riders from 180-320lbs (82-145kg)
CR: the weight-saving carbon fiber version of the LR and XR seatposts.
* 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, to accommodate the in-saddle riding style and weight distribution that e-bikes produce.
