ShimanoUltegra CS-6700 10-Speed Cassette(Return to Product Page)

Replaced a well worn Shimano cassette and chain at the same time. Both new components work well together.

These parts were used to rebuild an old (1982) steel frame bike. Nice improvement!

As always, Shimano components perform to expectation. I have used Ultegra group for many years and they wear well and provide excellent smooth shifting. Keep the chain clean and the cassette will last for about 4,000 miles on a road bike. With BTD you also get a good price.

Just swapped the standard 12-25 to an 11-28 on my road bike. Love the range. Shifts smoothly and crisply, plus looks great. Can't ask for more in a cassette.

This was an upgrade to make the hills a little easier. Not surprisingly, it was an easy fit to replace the existing Shimano 10-speed cassette. The 30 tooth cog was one size larger than spec'ed by Shimano for my derailleur, but it shifts well and didn't require a modification of the chain. Easy and inexpensive upgrade.

If I had paid more attention to my worn out chain, I wouldn't have had to change the cassette yet. It works, shifts good, no problems

11-28 paired with 34-50 chainrings.

Super smooth shifting with DA chain.

Getting older and needed the extra gearing for the hills!

I've used these for years! Nothing better out there!!

Paired this cassette with 105 components on my 2013 Trek Crossrip. Worked great.

Like all race ready Shimano components, they work well flawlessly. This cassette is no exception. I purchased it to replace the same one I've had for the last six years. I put the old one on my second wheel.

It's an Ultegra 10 speed cassette. Low frill, more reasonably priced, decent enough weight. It's the top of the value bracket. I put this on a smart trainer and it's perfect.

The 12-30 gear range allows this retiree to be successful on 15% grades. I'm a sprinter not a climber, but when you live in Western Pennsylvania there aren't many flat roads. Search for the Dirty Dozen bike ride and see some of our more exquisite hills.

Cassette works great

A superb upgrade over the heavier 105 that came on my TREK. Approx. 100 grams lighter and super smooth.

I dont have to tell you that shimano makes some of the best bike parts on the planet. This particular cassette is a mid level product that performs like a top of the line product. Highly recommend ultegra parts.

Making a decision on the internet on what store to order bike parts can be difficult. Friend of mine told me about this company. Will order all my parts from them. Customer service is great, shipping was on time. Good prices and selections of cassettes.

This was a gift to my son to use on his new TACX trainer. Has worked perfectly. Very smooth shifting. Everything just as it should.

Would buy again for myself or my son.

I find using all Shimano drivetrain parts results in a well-engineered system and smooth shifting. This cassette works very well with the rest of my bike.

Replacement of my original cassette with a larger 30 tooth cog. Excellent fit and quality.

Easy to install with the right tools. Glad I made the change to this cassette.
