Strengths: Reliable
Easy to fit if you have the right tools
Compatibly with other productsWeaknesses: Could be smoother with dura-ace chain
Expensive in AustraliaBottom Line: I went from a 11-23 CS-6600 Ultegra to 12-27 CS-7800 Dura-ace. The 12-27 is fantastic for very steep climbs. Weight is of reduced over the ultegra but the small gears on the dura-ace don't ride as well as the ultegra. I fitted a KMC X10-SL Gold chain and it made the shifting much smoother and quieter.
Bike Setup: Felt F3, Selle Italia SLR saddle, Ritchey WCS 4-axis alloy stem, KMC X10-SL Gold Chain, FSA ceramic bearing jockey wheels, All dura-ace except brake calipers

Strengths: 10-speed, smoother shifting, with less wear.
No chain-sucks for ~15K kilometers, which normally should already has happended by far.
i doesn´t semm to eat-op chains like mad, too.
Needde only two chains for the entire period.Weaknesses: Price, if you can´t afford it, if you can, it´s no weakness, but a good investment,imho.
Some 20-50 grams heavier than the 9-speed.Bottom Line: After switching from Dura Ace 9-speed to 10-speed components, I didn´t want to cut corners, so I spent my money all on genuine Dura Ace parts, for the name did hold true for the 9-speed and it does so for the 10-speed version of this cassette.
I´m surprised it lasts seeminlgy longer, than any 9-speed cassette before and I´ve done ´til now about 15K kilometers on it, many race kilometers, too, and it still shifts smoothly.
The chain had to be replaced two times, since and I´m deeply impressed, because I´m a little heavier than before and did succeed in sprints, more, and the cn-7700 didn´t last as long as the new chain, either.
Shimano holds word, if they say the durability has improved with that cassette, and I´m really keen on getting another one for the great longlasting performance without any issues.
But is this worth the price?-Seems so, to me, (un)fortunately for shimano.
No chain sucks, shifts more percisely, lasts longer.Top product!
