A cassette Shimano 10-speed, designed for the road

The CS-6700 is a solution particularly well-suited to the repair or maintenance of a bicycle fitted with a drivetrain Shimano 10-speed. Its steel sprockets and aluminium bracket help to combine strength, rigidity and weight management. Depending on the gear ratio, the weight varies by approximately 209 to 258 g.

Hyperglide technology from Shimano uses a tooth profile and gear-change aids positioned on the sprockets to help the chain move from one gear to the next. The aim is to achieve smoother and more efficient gear changes, particularly when changing pace.

The different tiers available

The choice of cassette depends mainly on the type of route and the gear ratio required:

• 11–23 teeth : closely spaced steps, particularly suitable for fast, relatively flat routes.

• 11–25 teeth : a versatile all-rounder for road riding.

• 11–28 teeth : makes climbing easier whilst retaining a small 11-tooth sprocket.

• 12–25 teeth : closely spaced, progressively increasing gear ratios, ideal for routes where you frequently need to find the right gear.

the Shimano The Ultegra CS-6700 remains a particularly attractive cassette for maintaining or restoring a road bike drivetrain Shimano 10-speed. Its main appeal lies in the quality of its gear spacing and the precision of its operation, thanks to the Hyperglide system.

For versatile use, a 11–25 or 11–28 is generally a sensible choice depending on the terrain encountered. Cyclists who mainly ride on flat roads may prefer a tighter gear ratio, such as 11-23, whilst a 12–30 makes it easier to navigate steep sections.

Expert advice: Before placing your order, please ensure you check the gear range of your current cassette and the compatibility of your rear derailleur. Shimano has provided several sprocket combinations for the CS-6700, and the derailleur’s capacity may vary depending on the drivetrain configuration.

Compatibility

It is particularly suitable for configurations using components from the Shimano Compatible with 10 speeds, provided that the derailleur’s capacity and the chosen gear ratio are observed.

How can I tell if my cassette is worn out ?

A chain coming off the teeth when accelerating, less precise gear changes or a chain that struggles to stay properly engaged can be signs of wear. Ideally, the cassette should be checked at the same time as the chain, as a heavily worn chain can accelerate wear on the sprockets.

The cassette Shimano Is the Ultegra CS-6700 suitable for an older road bike ?

Yes, it is particularly useful for maintaining or restoring a bicycle fitted with a drivetrain Shimano Compatible with 10-speed systems. However, you should check the freewheel standard; the 6700 series is characterised in particular by its design, gear spacing and finish. When restoring or maintaining an Ultegra 6700 drivetrain, it also allows you to retain the same number of speeds and gear ratio configuration.

Why choose an Ultegra cassette rather than one from a lower-end range ?

The appeal of the Ultegra CS-6700 lies, in particular, in its design, gear spacing and build quality. When restoring or maintaining an Ultegra 6700 drivetrain, it also ensures that the configuration remains consistent with the original groupset.
