    Step down, go long.

    Shimano’s Ultegra-level cassettes are one of the gems of cycling components. Significantly cheaper than the top-line Dura-Ace offerings, they’re also more durable, and only slightly heavier. And, they’re heavier in the center of a wheel, where their effect is negligible.

    Shimano’s improved its shifting ramps on this iteration, too, meaning the fabulous shift quality you expect from the Japanese component giant is even better than you remember.

    • Tallest cogs riveted onto aluminum carrier for durability
    • Variety of ratios for versatility

    Perfect mountain gearing

    • Familiarity: I've used it several times

    I needed extra gears to climb the mountain passes around Boulder. This cassette has the ideal gears for the steep climbs without jumps being too big to make shifting ragged.

    Excellent cassette

      Have 1500 miles on it so far and I’m loving that it’s still in very good condition! Wish they had the 12t option

      Great product

      • Familiarity: I've put it through the wringer

      I bought this for my smart trainer, and it works as expected.

      hard to beat

        Excellent price point for the quality you are getting, this cassette is a blast

        Light, durable, and cost effective

        • Familiarity: I've put it through the wringer

        I have this on my every day bike. My favorite gear has yet to burn out. Can't be happier.

        Great cassette!

        Easy to install, great quality and lighter from my old 105 set. put them on my race wheels and they work great. I went to the 11x28 to give me 1 higher gear and 1 lower gear and that's helped my riding a lot.

        Inexpensive lightweight-ness...

        Love these 10 speed cassettes! Lightweight, cheap, and crisp shifting. Plus backcountry always has great deals on them!

        Inexpensive lightweight-ness...

        Great Cassette

        • Familiarity: I've put it through the wringer

        I use the 11-25 on a DH bike and it works great. Shifts super crisp and is fairly light weight

        Great Product

          Solid Shimano Performance.

          Best for the Money

          • Familiarity: I've put it through the wringer

          I have used DA, Ultegra, Sram 1050/1070/powerdome and a few other smaller brands, and keep coming back to the ultegra. The higher end cassettes wear out too quickly, even for racing only my DA cassette was toast after less than one season and the Sram Red was not much better. Ultegra is the best balance between shifting performance, weight, and long life. For 85 bucks you really can't beat it. In fact i have an Ultegra 11-25 that i have over 30,000 miles on and its still truckin.

          rock solid performance at reasonable $

            simply works. not too heavy, very strong/durable, and the price isn't outrageous. i'm running dura-ace cranks on main bike, and ultegra cranks on my 2nd bike, both 53/39 with the 12-30 ultegra cassettes which give me some extra range, especially at the lower-end for climbing. the jumps on the bigger cogs in the cassettes are noticeable to the eye, but shifting is still very smooth with both bikes using Ultegra Di2 derailleurs. great all around product.

            Bang for your buck

              If you want to shed a few grams, then put that croissant down. No need for Dura Ace, and compared to Sram's older high end cassettes these Ultegra cassettes are much cheaper and quieter. Worth every penny, and when you can find them for around 50 it is even sweeter. Shifts are smooth and quiet.



              I use Rival shifters, brakes, and rear derailleur with an Ultegra 12-25 cassette, Ultegra front derailleur, Sram Red 53/39 crankset, and yokozuna cables. Couldn't be more satisfied with the performance of my Frankengruppo drivetrain

              Solid and reliable

              • Familiarity: I've put it through the wringer

              My favorite cassette by far, great shifting and price allows me to have enough cassettes for training and race wheels.

              Performance at the right price

              • Familiarity: I've put it through the wringer

              This cassette offers many different sizes for different terrains. I use a 12x23 on the flat roads where I live and a 11x25 when I travel to the mountains. The shifting is excellent and the price point allows you to replace the cassette as it wears out without breaking the bank.

              Excellent

              • Familiarity: I've put it through the wringer

              I think I've said this before on other items but its true: Its Shimano! its going to be awesome. I've ridden Dura Ace, 105 and Ultegra and for the money Ultegra wins hands down. I went with 11-28 for cross season.
