ShimanoUltegra CS-6700 10-Speed Cassette(Return to Product Page)

Your bike probably has highlow rear cogs you don't use. Get a tighter cassette - awesome upgrade!

If you can't spring for the ridiculously priced DA or SRAM Red cassettes, Ultegra offers great quality, reasonable weight and a wide variety of gear-size options for a very affordable price point. I own at least six of these cassettes, in various tooth sizes, and they just do what they need to. Before living in Maui, I raced CX every year in Oregon and used these cassettes in brutal conditions where they'd get completely abused, packed with mud and debris and forced to keep on going. After post-race clean up, they were good as new. Important to always grease the splines on the cassette body when installing to extend the lifespan of both cassette and cassette body.

Threw this on my trainer wheel, does the good perfectly.

Offered at a great sale price, so I snapped it up!

Replaced a SRAM PG1070 w this. Comparable quality, shiftability. Maybe a tick heavier, but a better value.

easy shifting, gear ration great for mountains and hills. easy to find right gear for a heavy rider.

I am using the 11x23 for crit racing. I found that the Ultegra cassette works very well with my drive train.

Smooth shifting and smooth shopping.

Gives me more in between options than my old cassette

So many teeth.

I've used both Dura Ace and Ultegra - DA may be 10% better but Ultegra works fine.

As long as your derailleur is correctly adjusted this will shift well. Sharp and clean shifts. I used it with Dura-ace derailleur

What else can you ask for? Good price, good wear, shifts flawlessly.

Shimano knew that the Ultegra 6800 cassette would reside as the heart of the new 11-speed system, which is why it devoted considerable time on a feature known as 'rider-tuning.' What this means is that you receive an updated range of useable gearing options with the advent of the 11-speed design.

Smooth shifting

II have not used the new cassette because of weather restrictions, ICE and SNOW

Arrived as advertised,can't wait to try in on my bike in the spring.

The cassette is fine. I think I should have gone with more gears. :)

Works great ,no problem shifting last for many miles .

Solid cassette. Smooth and reliable.
