Question: Received from Cyan Digital in a carton box with the cassette wrapped into bubble wrap. No retail box, has instructions, no warranty card. Safe to use?
Document: I use this cassette on my GT Road bike with an Ultegra chain and it works great. Durable, reliable, and a nice low gear for getting up the steepest of hills with just two rings in the front. I would normally give this 5 stars - but I am deducting one for Planet Cyclery. I will NOT order from Planet Cyclery again. I received this cassette in a bag. There was no Shimano box or labeling of any kind and the unit was in pieces. It was a joke.
I am not satisfied with my purchase because i asked a Shimano CS-6700 Ultegra Bicycle Cassette (10-Speed, 11/23T) and i received a shimano ultegra 6600 12-23 what is not the one i asked, besides the product did not come in the original box.i was expecting to gift this product but in this condition it was impossible.
I use this cassette with both Shimano and Sram component (chains and derailleurs) and they have never let me down. Aside from the Sram Red Powerdome, Sram's cassettes that are similarly priced are of much lower quality than the 6700. The 6700 is very easy to clean and the construction is the best on the market for this price point. There is no other logical cassette to choose.
But when I'm buying a new unit and paying a new price - I expect a new - in the box unit in one piece.
I would have used my local indie bike guy but after talking to him about prices, he said &#34;get it from amazon, I can't match the price&#34;  But...I had him switch my shtuff around so I could use an old wheel on my spinner (main reason I bought a new cassette).
I was a little hesitant to try and install a cassette myself. I found out it only takes a few minutes to put together on your freewheel hub and will save you a gob of money doing it yourself. It was a little scary when I saw the gears all apart in the package but the instructions Shimano gives are easy to follow and if you keep your old cassette nearby you can see how easy it goes together.
I use the Ultegra cassette on all of my road bike. The shifting is always sharp, firm, quick and quiet. Easily as good as Dura Ace for a lot less money and a small weight penalty. For what it's worth, all my bikes are equipped with Sram Red and KMC X10SL chains and I couldn't be happier. My riding mates often comment on how quiet my drive train is. Highly recommended.
Have a Cannondale Six(3) with a short RD and an original 12-25 cassette along with a Front compact chainring Q-ring.Having done some homework, I was cautiously optimistic that I would be able to switch out to a 12-30 cassette. Some adjustments are necessary and I am sure I am at the limits of the derailleur however I was able to use this set up for a hilly ride in the Catskills.
I wanted smaller gear spacing between cogs so I replace my 11/28T with this 12/25T. Definitely lighter than my old 105 cassette. The Amazon seller I got it from just had the parts in a plastic bagging--I was kind of bummed out about that but all the parts were new and nothing was missing. Works well so I guess I can't complain. I did download the instructions online since nothing was included.
I use this together with my 53/39 front and it works great on all hills I ride while still giving me an awesome gear on the flats for hammering. I really like the pricing on the Ultegra too, almost as good as Dura-Ace but much cheaper.
