greens didnt last long!!!! wtf!!! my greens have worn maybe a mm in the time i have had them off mark. i grind my rim a little too often too lukes koxx browns are amazing. i had a go on a bike with reds they were really really good.
btw even with the open bearings the tensile rocks. marks felt awesome today, so solid. nothing like an acs, almost immpossible to tell the difference from an eno. easier to clean too, just flush through with gt85.
