Shimano 105 CS-HG700-11 11-34T

The Ultimate Climber.

Don’t let the terrain dictate your ride. The Shimano HG700 is designed for the steepest grades and the longest days in the saddle. Offering a generous 11-34T range, this 11-speed cassette provides the "rescue gears" you need to maintain a smooth cadence when the road tilts upward, all while maintaining the crisp, reliable shifting Shimano 105 is known for.

Why It’s a Shop Favorite:

• "Go-Anywhere" Gearing: With a 34T largest cog, you can achieve a 1:1 gear ratio (or lower) on most modern drivetrains. It’s the perfect upgrade for riders heading to the Blue Mountains or tackling technical gravel routes where a standard road cassette falls short.

• The "Hub-Saver" Spacer: This is the most versatile cassette in Shimano’s lineup. It is designed to fit on both 10Speed and 11Speed road freehub bodies (using the included spacer). If you have an older high-end wheelset you aren't ready to retire, this cassette is your ticket to 11Speed performance.

• Hyperglide Technology: Precision-engineered tooth profiles and "shift ramps" ensure that your chain moves quickly and quietly across the cogs, even when you're shifting under pressure on a climb.

• Durability for the Long Haul: Constructed with nickel-plated steel cogs and a lightweight aluminum spider, the HG700 is built to resist corrosion and handle high-torque riding season after season.

The Alegro Build Tip: If you're using your FiftyOne Sika for light gravel or hilly gran fondos, the HG700 is our top recommendation. It pairs perfectly with a long-cage (GS) rear derailleur to give you the confidence to tackle any elevation profile.

Tame the climbs. Upgrade to the 11-34T HG700 and never run out of gears again.
