I have the 18" on my rear wheel, would have liked to have gotten a front as well but not offered in a 21". I have had it on about a year and have less than 5k miles on it and already feel like it needs to be changed. Great in corners and twisties I can lay this baby over in a turn but I will be going back to the Metzler ME 880 to match the front. It didn't out perform the Metzler enough for me to get another.
