Why don't we have 36 tooth cassettes?
Press are getting excited about XX but it seems like it has 2 big advantages... The wider range cassette, and 1:1.5 ratios at the front. (ie, 24/36, 26/39) for cleaner shifting. And close ratios with the 10 speeds of course. Now, it seems to me that 2 of those could be done right now with 9-speed, and that all that's holding us back is the 34T cassette. Is there some reason I'm too daft to see that nobody's making a 36-11 9-speed block already?
