Shimano Ultegra R8000 11sp Cassette now available in a wide array or gear ratios
Lightweight high performance cassette with alloy carrier and steel cogs
Lock ring included
Ultegra cassette works with Dura-Ace and 105 just as well
The 11-speed cassette is available in 11-25T, 11-28T, 11-30T, 11-32T, 11-34* , 12-25T and 14-28T versions.
*Please note the 11-34T is the CS-HG800 version which is compatible*
I was looking for a cassette ratio that would help maintain cadence on extended climbs and this Ultegra 11-30 was just enough of an improvement over 11-38 to help. Also, as used with me DA Di2 drive train, it required no modification to rear derailleur cage or chain length in order to work immediately.
