I`ve been buying this tire in this size 26-2.3 for a couple years. Unfortunatlly WTB has stopped making this size. The last one I bought was undersized and was actually more like a 2.2 or a 2.1. Not to happy about it, if you have experienced the same let Gary Gleason at WTB know about it. maybe several complaints will convince him. The tire is a fast rolling tire thats great in everthing except mud.
