Shimano 105 CS-HG710-12

Wide-Range Endurance Gearing. Smooth Hyperglide Precision.

The engineering highlight of the Shimano CS-HG710-12 Cassette is its Hyperglide tooth profile architecture. Specially shaped shift ramps and tooth contours guide the chain smoothly between sprockets, delivering crisp, quiet gear changes under heavy pedaling loads. With a massive 327% gear range, the 11-36T spread gives 2x road and gravel riders the ultimate bail-out gear for sustained, steep climbing without sacrificing top-end speed on high-speed descents.

Why the CS-HG710-12 is the Ultimate Endurance Upgrade:

• Expansive 11-36T Gear Range: Provides an extra-low 36T climbing gear that drastically reduces leg fatigue on steep mountain passes and loose gravel gradients.

• Hyperglide Precision Shifting: Formed tooth ramps provide fast, silent, and reliable upshifts and downshifts whether you are spinning casually or pushing hard out of the saddle.

• Standard HG Freehub Spline Compatibility: Uses Shimano’s proven HG freehub body spline pattern, making it fully backward-compatible with standard 11Speed road freehub bodies. No expensive wheel replacement required.

• Optimized Mid-Range Steps: Engineered with tight cadence jumps across the middle sprockets to help you maintain your ideal pedaling rhythm on flat and rolling terrain.

• Durable Nickel-Plated Steel Cogs: High-strength steel sprockets resist chain wear, rust, and corrosion over thousands of high-mileage training miles.

The Alegro Perspective: The HG710-12 is our top recommendation for riders who want to spin up steep hills instead of mashing their knees into oblivion. Standard road setups often stop at 34T, but that jump to a 36T cog makes a massive difference when you hit double-digit gradients after four hours in the saddle. Best of all, because it fits onto standard 11Speed HG freehub bodies, you can drop this 12Speed cassette onto your existing wheelset without needing to buy a new freehub body or wheel upgrade.
