Quite Happy

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.

Best quality for the money

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.

Great climbing cassette

Great price and good range of gears from this cassette. Great for climbing.

good enough

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 Workhorse

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.

Reliable cassette

Good cassette with typical bulletproof Shimano quality. Use on my Fulcrum Racing 3 racing wheels and have not had any issues.

Solid and reliable

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.

Great for the price

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.

Great cassette, very strong and lasts well

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.

Almost perfect

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.

Top bang for your buck

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.
