Rusted Casset x 2

I recently bought two of these Cassets from ProBikeKit and after only a month or so of use both are completely rusted. I have had the same Ultegra and Dura Ace Cassets on both my road and TT bikes for years with no issues. I decided to rebuild the drive train on both and have had both cassets rust out on the same timeline with the same quality care, (no water, and I haven't even had a chance to wash the bikes yet since they have not been ridden but a couple hundred miles) It is really strange I would say. it is almost as if these are fake Shimano Cassets the way they rusted through so fast. I will be putting my originals back on.

Perfect Shift

Upgraded wheelset needed another cassette. Perfect upgrade that does wonders for a great ride.


The best price on a proven part.

CS-6700 Cassette

This is a very good cassette with excellent build quality. I would recommend this cassette for anyone who wants low gears.

Excellent value and performamce

Can't find a better price for the Ultegra 6700 cassette. Shipping a bit slow to the U.S., but we'll worth the wait. Great product, good shifting. Wonderful company.

Ultegra cassette

Great buy as usual and great service

Great product - performance and a value!

Have used 11-28 and 12-30 Tiagra, 105 and Ultegra cassettes on two bikes over the past few years. I definitely like the Ultegra cassette the best. Shifting performance definitely improved with the Ultegra cassette and the difference in weight in the driveline is noticeable. For the small price difference, Ultegra is definitely the way to go for a replacement cassette unless you're trying maintain a super tight budget.

OEM replacement

Still using the original after 13,000 miles and 2 1/2 years. Know it should be replaced based upon that, but no sign of any necessity to do it yet.

Shimano Ultegra CS-7600 bike cassette 10 speed

This is a lower gearing then my last cassette and it makes a big differance. The cassette shifts smooth and quite, I have about 200 miles on it and found no problems.

Ultra cassette can't be beat!

It's a Shimano ultegra cassette so yeah its good! I got the 12-25 to replace my 11-25 and I really like it. Having the 16T is great and shifts smoother through the bottom. I really don't miss the 11T I just spin up the 12T and get in a tuck when going downhill and I am going about the same speed.
