Industry Description:
Key Features and Compatibility:
- 9-Speed System: This cassette is designed exclusively for a 9-speed drivetrain. It must be paired with a 9-speed chain (e.g., Shimano CN-HG93) and a 9-speed rear derailleur and shifters (e.g., from the Dura-Ace 7700 or Ultegra 6500 series). It is not compatible with 8-speed, 10-speed, or 11-speed systems.
- Hyperglide (HG) Technology: The CS-7700 uses Shimano’s Hyperglide technology, which features specifically designed tooth profiles and ramped shifting gates. This ensures quick and quiet shifts, even under load, which was a significant advancement at the time.
- Cog Ratios: The 12-25t range provides a tight set of gears, ideal for road racing and performance cycling where smaller jumps between gears are preferred. The specific cog progression is typically 12-13-14-15-17-19-21-23-25.
- Freehub Compatibility: The cassette is designed to fit on a standard Shimano Hyperglide-compatible freehub body. This is a widely used standard, so it will fit on a vast majority of Shimano, SRAM (pre-XD/XDR), and other compatible hubs.
- Construction: As a Dura-Ace component, it is made with a combination of high-quality materials to reduce weight while maintaining durability. The largest cogs are often made of titanium for weight savings, while the smaller ones are durable steel. The cassette is also designed with an aluminum carrier to further reduce weight and improve stiffness.
- Vintage/Retro Builds: Due to its high quality and legendary status, the Dura-Ace CS-7700 cassette is a very popular choice for enthusiasts building or restoring high-end road bikes from the late 90s/early 2000s.

A little about the seller:
I’ve been in the cycling industry for more than 30 years (I know, that makes me old!). I’ve been a professional bicycle mechanic for most of those years, including working locally at Lee’s Cyclery before they became Trek Stores. Now I work from home as a Customer Success Manager for a software team. But I still love fixing up and working on bikes and riding them too!
Purchase from me with peace of mind. Not only can you trust my years of experience, but I will also fit you for the bike and provide any mechanical insight at the time of purchase.
Shipping information:
I ship USPS Ground. I try to keep it simple. It will be packed very well, but if you see any damage to the box or Part, keep the box and packing material plus, take pictures. I do insure all parts that are shipped. In addition, if shipped out of Colorado, there is no Sales Tax. You can also combine shipping with multiple items.
