This innovative upgrade on Shimano’s classic 660 and SL versions features reduced weight, ni-plated Hyperglide sprockets with improved teeth shaping and revised ramps for smoother, quicker and more accurate shifting.

I'm very happy with the cassette. It is what I was expecting and the delivery time was surprising
Great change from the 12-27 I was using before. I am a stronger climber but I ride a mix of hills and flats, this cassette works perfectly for both.
I like this cassette, but like the chain that goes with it, it does not seem to last too long before it wears out.
Fast delivery, the ratio was what i order. fit right in my C50 wheel without ajustement. Shiffing is very nice. Thanks again proBikeKit.
Installed on a 10 speed duraace 7800 groupset runs perfectly smooth the 30 is a must in mountain you deserve it
For the price, unbeatable! tough and very good shifting...
Ordered Shimano Ultegra CS-6700 Bicycle Cassette - 10 Speed and it arrived quickly. Exactly the product I wanted. Thanks
Wow! Huge value when I bought it on sale. One of the few models out there with the 18 cog. Always happy with Ultegra quality.
Just a few grams heavier than its DuraAce big brother, but at 1/3 of the price. For those who pay their bike parts with their own money and still want durable and reliable components. I honestly don't know which wears out the slower, the Ti cogs of DA or the steel ones of Ultegra, but again, at 1/3 of the price, it's a no-brainer.
Product was received on time and was exactly as advertised - very satisfied.
Great price and good range of gears from this cassette. Great for climbing.
I bought this Shimano Ultegra CS-6700 Bicycle Cassette to go on my new rear disc race wheel. I didn't expressly check compatibility with my chain or rear derailleur, but the stock training wheel had Ultegra 6600 (I think) and swapping wheels hasn't caused any issues.
Good in many ways. Reasonably priced, durable when matched with the right components, with reliable up and down shifting; Good training cassette and moderate to good race cassette depending on race conditions. Can't honestly say I have encountred any major problems with this cassette.
Good cassette with typical bulletproof Shimano quality. Use on my Fulcrum Racing 3 racing wheels and have not had any issues.
I have been using this cassette for over a year now and have not had any issues. It performs under all conditions and cannot find any reason to change.
I always run Ultegra cassette's in my training wheels reserving Dura Ace for race wheels only. Ultegra cassettes represent great value as the weight and performance penalties are clearly worth it for the price.
I initially bought one of these cassettes to replace the standard 105/5700 cassette which came with my bike (on a recommendation of a friend, despite only doing 2000km's).
Coupled with a dura-ace 7801 chain (initial chain was a KMC), the running gear ran so much more smoothly. I did about 5000 km's on my first 6700 cassette, and after replacing it with another 6700 cassette, I was impressed with how well the first had lasted, and that it was still very smooth to shift and smooth in general riding.
Great price for a quality product.
Great cassette. Close to the lightest, the Shimano hyperglide system still trumps all shifting. Make sure you purchase with a matching 7900 or 6700 chain for 100% performance. For the price this is so close to getting 5 stars from me.
I'm running one of these in a 11-23 on my TT bike and it really is the best performance for dollar cassette I have come across. Sure you can go lighter but for a much higher price. The shifting is consistent, smooth and pretty quiet. I have also found this to be a bit more durable than the 7800 and 7900 Dura Ace cassettes. I would only go for the Dura Ace above this cassette if you are looking to save every last gram.
