Shimano CS-6700 Bicycle Cassette Sprocket

Shimano Cassette

Just as good as Dura Ace (I think). When your shifting becomes noisy and seems to hit between the sprockets, check your chain for wear and stretch and replace as necessary. I don't know how to physically check the cassette, but after a period of time... replace. An inexpensive piece of maintenance for your riding comfort. Do it yourself with a sprocket remover and a chain whip. See youtube videos for help. I like the 11-28T because the extra lower gear really helps to keep from using the small front chain ring. Love the feeling of a new drive train!Read full review

Excellent Quality

I purchased this to help make my bike faster. That it did! It’s surprising how reducing the number of teeth by one can make that much of a difference. The strength of the cassette hasn’t decreased even though it’s a smaller diameter.Read full review

Lightweight with great features

At this time and all other times, since I've been using shimano ultegra cassettes and shifters on all my bikes therefore I have nothing bad to say about this product. It has all the characteristics that I need in a sprocket, it shifts faster with my ultegra derailleur too.Read full review

Ultegra 12-30 cassette

I have used this cassette before for hill climbing. It works great with Shimano 7900 and 6700 derailleurs. The added gear makes the steep hills much easier on the knees and the lungs. Highly recommend.Read full review

Works great!!

Works great I took out the 14-12 and installed 11-13 from my 11-25 to get a custom 11-30 for my 10speed drive train. Works awesome shifts great nice to have the 27,30 on top to climb up and the 11 on bottom to fly down.Read full review

Large Shimano 12-30T Ultegra Cassette

The item was perfect but I made the mistake of buying a 30T when the cassette I needed was a 11 or 12-28T or less.

I expect this cassette works with a shimano triple but it's too many teeth for my dura-ace 10-speed set up. Read full review

Go Ultegra!

Ultegra 10 speed cassette is the best value to quality pick .Dependable and durable.
I have used this cassette numerous times and always come back to it!

not used, broke in

excellent condition for half the price of new. A great way to upgrade a 105 to a ultegra.
