Racing on end of life tubulars is not a fun way to end a season.
How much life did you get from the crono cs? I just bought two of those to replace mine and I am curious what you got. I will be racing at Alpenrose and Marymoor, so not the smoothest of tracks.
I had one crono go 2 years and over 100 miles at Marymoor then went on the front of a training wheel for another year. That last few have been victims of rugby practice bottle shards so not so lucky the last couple of years. But they do wear pretty well at least on the smooth concrete at Marymoor.
