Got gears you don't use?

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

First time replacing a cassette.

First time to ever change out a cassette, wow a very easy process. After replacing the cassette check out shifting with your chain and your back on the road again. 10 minutes max to replace a cassette. Faster than replacing a flat tire! Save few bucks, do it yourself. My old Shimano cassette a little over 8,000 miles still working but thought with a great price at Bike Tires Direct why not replace the cassette. Shimano TOP quality products along with Bike Tires Direct, my go to online bike store.

Solid Value, Great Quality

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.

Good Group Set

I find Ultegra cassettes bullet proof and a good value for my training bike. They are relatively inexpensive and last a long time if you take care of them. Highly recommended.

Great value

I am still running 10 speed. Needed a new cassette for a new Hed wheel. For $XX, these are incredible deal! The finish holds up really well, too. Seems to be more durable than Dura Ace for a lot less $ and just a little more weight.

Perfect product

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.

Well made, crisp shifting

Good product by Shimano. Still think price could be a little lower since they are mass produced. I do like the quality control though. Decent packaging. Product could come with an extra bottom spacer.

Shift into gear with a new Shimano Ultegra CS-6700 cassette!

The Shimano Ultegra CS-6700 cassette is a workhorse cassette and is a great deal on BikeTiresDirect. have two bicycles with Shimano 10 speed components (105 and Ultegra ) and opted to replace the cassette and chain, swapping the 105 components for Ultegra. This was a no-brainer . . . great components at a phenomenal price! You really can't go wrong with the Shimano Ultegra CS-6700 cassette - if you've logged several thousand miles on your drivetrain and you haven't replaced it yet, now is the time to secure a great deal on a cassette/chain - replace your cassette today (your bike will love you for it!)

So you may be asking yourself, why don't I just buy the Shimano 105 or the Dura Ace? The Ultegra is the best of both worlds - it's lightweight but durable enough to withstand thousands of miles with little wear (as long as you maintain your drivetrain with cleaning and proper lubrication).
