Refined and simplified title: SHIMANO CS-6700 Ultegra 10-Speed Bicycle Cassette

When it comes to choosing between Dura-Ace and Ultegra cassettes, we acknowledge the appeal of Dura-Ace but also recognize the practicality of opting for Ultegra on your bike. Many savvy cyclists opt for Ultegra cassettes to save money, which can then be allocated towards other weight-saving upgrades. The Shimano Ultegra CS-6700 Cassettes, weighing 7.4oz (209g), are notably lighter than their 6600 counterparts, narrowing the performance gap with Dura-Ace.

One significant advantage is the design where the largest cogs are affixed to an aluminum carrier, effectively reducing overall weight. This configuration not only saves grams but also ensures a gentler interaction with aluminum cassette bodies, prolonging their lifespan.

Here are the available cog sizes: 11 x 23 t, 11 x 28 t, 12 x 23 t, and 12 x 28 t. These cogs are made from durable steel, ensuring longevity and reliable performance under demanding conditions.

The cassettes feature Shimano's Hyperglide freehub type, which facilitates smooth and precise gear shifts, crucial for competitive cycling and demanding terrain.

In summary, while Dura-Ace remains appealing for its top-tier performance, opting for Ultegra cassettes proves to be a smart choice for cyclists aiming to balance performance and budget. With their lightweight construction, thoughtful design, and compatibility with aluminum cassette bodies, Shimano Ultegra CS-6700 Cassettes offer a compelling option for enhancing your bike's performance without breaking the bank.
