Shimano CS-6700 Ultegra Bicycle Cassette (10-Speed)

I picked up the Shimano CS-6700 Ultegra 10-speed cassette to use on my Wahoo KICKR Pro trainer, and it’s been a perfect fit. Installation was simple — it mounted right onto the freehub body with no compatibility issues. The shifting is incredibly smooth and precise, just like you’d expect from Shimano’s Ultegra line. Noise levels are low, even during high-power intervals, and the gear spacing feels natural for indoor training. It’s also held up well through a lot of sweaty sessions — no skipping or uneven wear so far. If you’re running a 10-speed drivetrain and want your indoor setup to feel identical to your outdoor bike, this cassette is an excellent choice. Smooth, durable, and worth the few extra bucks over the lower-tier models.

Of course the new chain slipped over the 2 very worn low sprockets (Dura-ace from 2008!) and this new cassette was the solution. works perfectly

Fits nicely on my new wheel build. No spacer necessary. But it does come with one just in case. the chain line is still correct. Even for an old steel road bike conversion.

llegó en excelentes condiciones. ya lo instalé y quedó muy bien. ya fui a pedalear y sirvió muy bien.

I got this cassette as a long overdue upgrade for my road bike (had 12 years of frequent riding on my original drivetrain, so I got new cassette, chain rings, chain). I’m super happy with this cassette. The quality is excellent - very sturdy build yet still relatively light weight. And the proof is in the riding: my bike shifts like a dream!

I bought a "used - mint" cassette and it came with no outer package, no instructions, wheels scattered loose in a plastic bag, and appears to be missing one spacer. That's not "mint". It's not even "complete". At least all the wheels are present, and the main spacers. I am hoping, hoping I can re-use the missing spacer from my old set.

Here's a scenario: You go down to your LBS and pick up a bike off the shelf. "Wow, this is a great deal!" They tell you its a 105 bike and you are super excited to get a bike with great kit for a great price. You get the bike home and go for a few rides then a few weeks later start looking through specs to find out how you can make the rig faster (without training harder) Your local bike shop probably didn't bother giving you a full run down of every component so you go bike them on the Makers website and then you have this epiphany! "This isn't a full 105 bike or Ultegra (or what have you)" The brakes are actually a cheap Tektro variant, the crankset is probably something by FSA and the cassette in likely Tiagra. Now you know why your bike was so well priced. If you're smart you take the FSA crank off right away and post it on Ebay. hopefully you get $40-$50 and that can be plopped down for a new Ultegra crank that is super stiff and provides instant response. After that you tackle the rear Cassette and the jump from that Heavy Tiagra to Ultegra is immense. This Ultegra Cassette is fantastic. If you live where there are hills (10-15 degrees and up), you'll love this cassette. you'll be the guy laughing on group rides when your buddies on their fast racing bike with 11-21 cassettes or 12-23 cassettes are killing themselves out for the saddle crawling up big hills while you sit down and enjoy a nice casual stroll up the hill.

This cassette just slid right on after I cleaned up the hub a little with a file. I have a Dura Ace derailleur with specs that say 27 teeth is the max but Shimano was being conservative. I adjusted the "B" screw and things are just fine. My road bike climbs like a mountain bike and no longer ghost shifts or hunts between gears. Buying and installing this cassette changed the personality of my bike as it not only goes easier uphill but faster downhill. I could characterize this as an epic win. If you are considering installing this cassette, I would highly recommend changing your chain also. If the your gear ratios are being changed a new chain is a requirement.

DURA-ACEと比べると耐久性は劣るかもしれませんが、一般人レベルだとかなり長い間使えると思います。 フロントがノーマルクランクなのでワイドな11-28は激坂などで使えます。 シマノのクランクのおかげもあるかもしれませんがやはり切り替えがスムーズです。 普及価格帯の105よりも少し出費することでずっと使えるレベルの品質が手に入ります。

Cassettes are usually awkward to remove but easy enough to fit with the right tools. The Ultegra 10sp 11 to 28 tooth version is reasonably robust & light weight.
