Sram Red, 11/23 Cassette. This is the one with the red backing. It has barely been used and only for the last couple months of road racing last year, so maybe 500-1000 miles tops. It still looks brand new. Perfect criterium gearing although I used it for both road and crit races. I wouldn’t use anything different if you have a special wheelset that is more valuable than your daily training wheels.
$100 shipped.
I also have some 1070 11/26’s if you’re interested in those.
