More gearing options in a stiffer and lighter cassette. Alloy carrier increases stiffness and shaves weight. 4 largest cogs in titanium where they receive the most weight savings and wear longer than smaller cogs. 11/28 version must be used with RD-7900 rear derailleur. Best used with the 7900 chain but also compatible with the 7801 chain and Shimano's other 10-speed chains.

High quality for lower price.

Of course, Dura Ace is the best.. And of course, Bike Tires Direct has the best value in pricing. Fantastic combination. Great product at a great price!

Worth it

Smoother and sure-er shifting than James Bond working a stick in an Astin Martin. Plus it's light, and has the ultra sexy titanium gears.

Great Price!

Nothing shifts as good as the Dura Ace cassette. I installed this on my good wheelset and anxiously await Spring for me to get the good bike back out. Till then it's my clunker bike with the Ultegra groupo that shifts nice but definitely not as good and responsive as Dura Ace!

Pricey, but Excellent

I use this with a 7900 chain with Ultegra 6703 on the front. I think this works better than Shimano's recommended 6600 chain with the 6703 up front and ultegra cassette in the rear. I love the 11-28 option, as I do a lot of steep climbing. Nothing bad to say except - wow - pretty expensive.

No brainer

You can't beat the quality of Dura-ace. A 11-28 is a cheaper alternative to compact cranks for 55 yr old knees. Shifts just fine

Best quality at the very best price

I use this cassette on my Cervlo R3 and it it procures very precise and smooth shifting. And the price is far more better than in a bike shop here in Qubec.
