i was going to get a set, but the shop couldnt get them for some reason. i went ahead and got an 016 Pro put on the front since my rear 016 is still good. i liked the original 016's, but the front wore REALLY fast and really weird as well (middle still good, but the sides wore out VERY fast and the tire had a triangular shape and the sides were down to the wear bars).
i heard this was a common problem with the original 016. i didnt even ride too hard on it, although most of my riding was in the mountains. i was looking forward to the s20s, but i can wait until i wear out the rear and decide to get new tires.
