- Familiarity: I've put it through the wringer
I got these (21mm) when they were 50% off which makes them an absolutely killer deal. I do about 40 miles a day on them and they have held up for the last 600 miles. The grip and ride with these is phenomenal - just remember to run the pressures pretty low (70-90psi) and it will iron out most vibrations of a chip seal surface. Highly recommended, although they do seem to get small cuts quite easily.
