SunnySports S These are the 2008 model, the one currently on the Leki website is either the 2010 or 2011 model. Our specs are correct for the 2008 model. The Model number unfortunately does not change from year to year so the 2008 and 2011 models ar both T02030. Below is a link to the model we have on the Leki website, you will see that our specs are correct. http://www.leki.com/trekking/trekkingPole.php?pID=19 Stay safe and have fun out there! Neal
