Designed for serious cyclists seeking a high-performance drivetrain upgrade, it offers smooth shifting, reduced weight, and long-lasting reliability—all essential for competitive and enthusiast riders aiming to elevate their cycling experience. ## Description We'll tell you straight up that while we appreciate the appeal of Dura-Ace cassettes, we understand why you would choose Ultegra for your bike. Smart racers routinely save money by going with Ultegra cassettes; the money saved can go for other weight shaving measures. Shimano Ultegra CS-6700 Cassettes are lighter than their 6600 brothers, doing a nice job of closing the gap on Dura-Ace. The tallest cogs are riveted onto an aluminum carrier for weight savings, and they're more gentle on aluminum cassette bodies. Review: Shimano Ultegra quality - Cassette was as expected for Ultegra level quality. I was trying to decide between XT 10-32 cassette and this Ultegra 10-30 cassette. I am replacing an older Dura Ace 10-27 cassette. Looking for additional lower gear range. Dura Ace is super light. The XT was the heavier than the Ultegra. Decided to stay with Ultegra since I have Ultegra road group. Did not disappoint. Flawless shifting and smooth transition gear to gear. You will need cassette chain whip and cassette locking tool to remove and install the new cassette. Otherwise is very easy to install. Review: A Huge Imprvement over Tiagra - Here's a scenario: You go down to your LBS and pick up a bike off the shelf. "Wow, this is a great deal!" They tell you its a 105 bike and you are super excited to get a bike with great kit for a great price. You get the bike home and go for a few rides then a few weeks later start looking through specs to find out how you can make the rig faster (without training harder) Your local bike shop probably didn't bother giving you a full run down of every component so you go bike them on the Makers website and then you have this epiphany! "This isn't a full 105 bike or Ultegra (or what have you)" The brakes are actually a cheap Tektro variant, the crankset is probably something by FSA and the cassette in likely Tiagra. Now you know why your bike was so well priced. If you're smart you take the FSA crank off right away and post it on Ebay. hopefully you get $40-$50 and that can be plopped down for a new Ultegra crank that is super stiff and provides instant response. After that you tackle the rear Cassette and the jump from that Heavy Tiagra to Ultegra is immense. This Ultegra Cassette is fantastic. If you live where there are hills (10-15 degrees and up), you'll love this cassette. you'll be the guy laughing on group rides when your buddies on their fast racing bike with 11-21 cassettes or 12-23 cassettes are killing themselves out for the saddle crawling up big hills while you sit down and enjoy a nice casual stroll up the hill. ## Features - Aluminum carrier for 3 largest cogs - Nickel plating increases durability - Drilled out cogs help reduce weight - Includes lockring - Shimano Reference Number: CS-6700 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007Q4NUIC | | Best Sellers Rank | #29,014 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #6 in Bike Cassettes & Freewheels | | Brand Name | SHIMANO | | Case Material Type | Aluminum | | Color | Silver | | Customer Reviews | 4.8 4.8 out of 5 stars (1,378) | | Global Trade Identification Number | 00689228299726 | | Included Components | Cassettes | | Item Dimensions L x W x H | 12"L x 9.5"W x 0.5"H | | Item Weight | 0.01 Ounces | | Manufacturer | Shimano | | Manufacturer Part Number | ICS670010230 | | Material Type | Multi | | Model Number | ICS670010230 | | Mount Type | Clamp-On Mount | | Number of Teeth | 120 | | UPC | 689228299726 | | Unit Count | 1.0 Count | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** SHIMANO - **Color:** Silver - **Item Weight:** 0.01 Ounces - **Material:** Multi - **Mounting Type:** Clamp-On Mount ## Images ![CS-6700 Ultegra Bicycle Cassette (10-Speed) - Image 1](https://m.media-amazon.com/images/I/61YK0QNAB6L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Shimano Ultegra quality *by D***G on May 22, 2024* Cassette was as expected for Ultegra level quality.

Installation was simple — it mounted right onto the freehub body with no compatibility issues. The shifting is incredibly smooth and precise, just like you’d expect from Shimano’s Ultegra line. Noise levels are low, even during high-power intervals, and the gear spacing feels natural for indoor training. It’s also held up well through a lot of sweaty sessions — no skipping or uneven wear so far. If you’re running a 10-speed drivetrain and want your indoor setup to feel identical to your outdoor bike, this cassette is an excellent choice. Smooth, durable, and worth the few extra bucks over the lower-tier models. ## Frequently Bought Together - Shimano CS-6700 Ultegra Bicycle Cassette (10-Speed) - Shimano Ultegra 6701 10-Speed Chain - SHIMANO Guide pulley + tension RD -6700 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/1429648-cs-6700-ultegra-bicycle-cassette-10-speed](https://www.desertcart.co.za/products/1429648-cs-6700-ultegra-bicycle-cassette-10-speed) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-26*
