Quality and Quietly Smooth

This cassette is strong, shifts quickly and quietly when properly tuned. The weight savings over Dura-Ace is not going to be felt (certainly there are better ways to save weight--like put less water in your water bottle. Amazing value for the price and rock solid.

Great cassette

Upgrading my travel bike to account for mountainous destinations and advancing age. Wanted a 30 sprocket, so bought a longer cage derailleur and this CS 6700. Works wonderfully, and I'd definitely recommend it.

Nice 10-speed cassette

If you are riding a Shimano 10-speed drivetrain then this is pretty much the best cassette you can get. It comes with a 1.86 mm spacer so that the cassette can also be mounted on wheels designed for 11-speed cassettes. Easy to mount.

Great cassette at a very good price

I ordered this cassette for a friend who had some seriously-worn cogs on his old Ultegra 6700 cassette on his race wheelset. New cassette + new chain = crisp shifting again. PBK's price was unmatched, and delivery was on-time.

Ultegra Cassette

After my local bike shop indicated I needed a rear cassette and chain I starting comparing the pricing and was very impressed with ProBikeKit. Placed my order and 10 days later it was on my doorstep at a significant savings from my local options. Both the cassette and chain were in original Shimano packaging and in excellent condition. They have now been installed and have made the shifting much smoother. Would highly recommend as long as you have the time to wait.

Ultegra 6700

Ultegra is an incredible bang for your buck and lasts forever. This cassette gives you a few extra teeth for the steep hills here in Colorado, shifts perfectly, and you never have to think about it.

CS-6700 Ultegra Cassette

Bulletproof! I'm not sure why you'd go to Dura Ace on this kind of part. Not a component you want to shave weight on. I run Ultegra or 105 on all my bikes and they wear very well and last. Good value for the money.

Lightweight-Great Gearing

I purchased this cassette for two reasons. . . 1. I needed an additional cassette for my backup wheelset 2. I LOVE having 12-30 gearing! I chose this cassette because of it's weight (12-30 is 270g) my Tiagra 12-30 was over 340g. It shifts very smoothly but my rear deraileur needed adjusted slightly. Not sure why considering they were both the same exact gearing? If you haven't tried 12-30 gearing yet, you will probably love it. I have rather strong legs but the object is to work smarter, not harder on those ridiculous climbs. I could have went with a Sram 11-32 but I would have felt like a school girl spinning a 32 teeth cog :) Great Shimano quality, decent weight, excellent price, attractive ratios. Try one out!

Ultegra 6700 Cassette

These are the ideal compromise of weight vs. durability for a cassette for the recreational rider. 30 tooth gear on this cassette is a great ace in the hole if the hills get too steep or the rider too tired. These were provided as loose parts in a plastic bag like OEM parts would be packaged. This was not stated in the description but at the low price they were offered at, I would have purchased them anyhow. Missing the box is no big deal, but I like to have the plastic center piece to stack the pieces on after I wash them and before transferring them back to the freehub. If you have a 10 speed Shimano drive train this Ultegra cassette is a great deal that won't hinder performance.
