dirty thirty

Well folks, the time comes when you are looking at 60 years in the rear view mirror and realize you need a little more spin for those steep skyline hills. My solution, the shimano ultegra 10 speed cassette with a thirty tooth cog. yep for now this old guy can still spin up those steep hills and enjoy it! Where you say can I get one? Well greybeard, at Bike Tires Direct of course! I have bought my tools of the road from these guys for many years and never once had a problem, shipping is fast and the price spot on. Disclaimer I do not work for these guys, really. I Just appreciate them. Have a great ride and I will see you out there!

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.

The Ultimate road cassette

I have been using the Ultegra cassettes for years. You can spend much more on a cassette but you won't get a better one. These work as well as anything and just last and last and last. Dura-Ace might save a gram or two and work the same, but it won't give you the long service life the Ultegra does. If you want a cassette that you can install and more or less forget about all while enjoying beautiful shifts day in and day out - this is it.

Smooth shifting, good value

I needed to replace my 10-speed Dura-ace cassette because of worn cogs and was originally looking for a Dura-ace 10-speed cassette. Not only were they difficult to find, but the few I found were extremely expensive! I "settled" for this Ultegra cassette and I am very glad I did. Not only is it waaay less expensive, but the shifting is just as clean and crisp as my Dura-ace cassette. Even though I know there is a weight difference, I really can't feel it in any way. I have it paired with a SRAM hollow-pin chain and the combination works extremely well. I would definitely recommend this cassette.

Shimano Ultegra CS-6700 10-Speed Cassette race ready

Shimano Ultegra 10-speed cassette CS-6700 236g (12/25) $75 compared to Dura Ace CS-7900 163g (11/25) $180. Ultegra is only 73g (2.5oz) added weight over Dura Ace, but $110 less. That's about the weight of a Clif bar in your cycling jersey pocket ??. Ultegra is the intelligent cost-weight ratio choice. Wait for the next BikeTireDirect sales event and save an additional 20% !

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.

Good durable product

Replaced a well worn Shimano cassette and chain at the same time. Both new components work well together.

These parts were used to rebuild an old (1982) steel frame bike. Nice improvement!

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).
