Heidenau K61 100/90-10
We never sold a lot of that particular tire, and over the last month have sold at least 24 (a lot for us). I started asking what the big deal about this tire is. One of the purchasers told me that the official importer decided to stop importing this tire for the US market. We've got a bunch of them, and we'll get more when they are gone, direct from the Fatherland.
We can also get the Pirelli Angel series of tires out of Italy now for about what you are paying for the SL26, if anyone is interested.
