SHIMANO 6800 Ultegra 11-Speed Cassette

This works perfect with my 2018 Trek Domane SLR7 Di2 11spd setup. with a finer gearing selection. A fair price and free shippimg. Will buy again

Wanted to do a Di2 upgrade on my bike with a broader range cassette for climbing the hills and mountains of western NC. Shimano is quality and reliability. Works like a charm on my Dura ace Di2 bike (with the exception of this cassette and a medium cage Ultegra 6870 Di2 rear derailleur). Compatibility is great with the e tube Shimano system.

I'm going to race the IM Nice in June and I was looking for a cassette to help me in the steep hills. I rode on a 11-25 Shimano Ultegra and a Semi-compact crankset and I felt good, but I want to be extra safe that I can climb the 20% hills and the ports to the L'Ecre. I saw the cassette configuration and it has the gears to go on flats and downhill, while including the easy gears for the climbs. Tomorrow I will use the cassette in a 6 hour ride and I will post my comments.

Very good Cassette - easy to install (watch a Youtube video to make sure) - will need the extra small oval tightening tool (but not the chain tool) to install. I was only installing a new Cassette, not removing any old one, to a new purchased wheel.

First time I have installed a cassette myself.I purchased this to use on a solid disc wheel, usually I let the local bike store mess with this stuff - but in this case thought I'd give it a whirl. The cassette comes on a plastic holder in the correct cog - spacer configuration, I did not see any actual instructions and if I had been methodical I'm sure it would have been fine. As it happened I misplaced the last spacer and then tightened it up with the appropriate tool.It was not snug so obviously, I knew I had it wrong - online they have lots of instructions to get this assembly correct - but you did need a 'chain whip' to remove the assembly - fortunately I purchased one, knowing that I am not that methodical.Bottom line, got the thing installed - runs fine, very happy. Obviously, purchase the appropriate tools to tighten and loosen it - it is not rocket science, but if you are not that mechanical, you can set it up incorrectly. Obviously, there is always your local bike store...I purchased the 11/28 operating with a 53/39 chain ring set up - works fine for me.

I bought an ultra light full 853 steel frame bike recently and it came with a compact crank, 50-34 and a Shimano 11 speed Ultegra 8000 rear cassette 11-34. But i also wanted a similar quality cassette with a slight narrower gear range. This one just fit the bill.

I actually don't know if this works well with Shimano so I just gave it 5 stars. I bought it to go with my Force 22 setup because I was told that they were compatible (by a SRAM technician). SRAM doesn't offer a cassette starting with 12T which is completely lame. Anyhow, this comment is for those trying to do the same as me....this cassette WILL NOT WORK the same as a sram. Mine will not shift from the 5th cog from the top to the 4th cog. The rest of it shifts fine. I am stuck with the sram for now........

Bought this cassette as I have an upcoming two month cycling tour which will include the Pyrenees, the Alps, and the Dolomites. All research indicated that I would need this cassette for the 32 'bail-out' ring. My 6870 derailleur was designed to accommodate it. Cassette works perfectly and feels smooth. Product was received promptly at a reasonable price.
