Shimano’s 7400 series Dura-Ace was a game changer when released in the 1980s, over the years it introduced HG freehubs, STI shifters and SLAR brakes, all of which are still in use today. Seven speed UniGlide was the third iteration of cassette/freewheel available with the group, the Dura-Ace UniGlide system only works with Dura-Ace hubs and hubs will take both 7 and 8 speed cassettes.
This new in the box UG cassette is a 13 to 19 close ratio for road or TT bikes, tooth count is: 13; 14; 15; 16; 17; 18; 19.
