Shimano Ultegra CS-R8100 Cassette Beige 12s / 11-30t
The Shimano Ultegra CS-R8100 Cassette and Chain combo offer fit perfectly in the Shimano 12 speed groupsets. This Shimano Ultegra R8100 cassette is available in different ratios. This Hyperglide+ cassette includes the choice of the 'sweet spot' between the 6th, 7th and 8th cogs. These are the cogs most people most often and prefer to ride on and have therefore been reinforced and have small jumps between them. The Shimano XT M8100 12 speed chain will support you optimally while you're using your 12-speed Shimano groupset. This chain is designed according to the Shimano Hyperglide+ technology. This allows you to shift very smoothly, even with a lot of pressure on the pedals and under extreme conditions. In addition, this chain is relatively light and has a special coating and excellent durability. Shimano 12 speed allows the gears that ride most comfortably at average speeds to be retained, despite large ratio differences. The Hyperglide+ technology also delivers a 1/3rd shorter shifting time compared to previous cassette and chain combinations. Because this cassette features the HG cassette fitting, it is also compatible with all Shimano HG 11 speed bodies.

Been using this cassette with my Ultegra R8100 set-up for > 1,200 miles know and have found it to work flawlessly. I was initially concerned that the 1134T wouldn't have enough high gears for descending but other than missing the 16T cog of the 11-30T it has the exact same cogs.The hyperglide+ seems to work perfectly and shifting is quick and smooth.
Ultegra 12 speed 11-34 is a finely engineered piece of bike tech. Works very nicely
Delivered fast, good service. The product met expectations. Cassette was bought for winter pair of wheels.
replaced 1a 11-30 with this 11-34 for a 36/34 climbing gear. Quick shipping and arrived in time for a great wekend!
