Shimano CS-R7000 105 11-Speed Cassette 11-30T

What it is

The Shimano CS-R7000 is a:

• 11-speed road cassette
• part of the Shimano 105 R7000 groupset
• gear range: 11–30T
• designed for HG (Hyperglide) 11-speed road freehubs

It is one of Shimano’s most popular “mid-range race/endurance” cassettes.

Key features

• ✔ 11-speed Shimano road compatibility
• ✔ HG freehub body (standard road 11-speed)
• ✔ Steel sprockets with aluminium spider (lighter top section)
• ✔ Smooth Hyperglide shifting ramps
• ✔ Wide-enough range for climbing + speed balance

Gear range (11–30T)

Typical sprocket progression:

• 11-12-13-14-15-17-19-21-24-27-30

$\text{Gear Range Ratio} = \frac{30}{11} \approx 2.73$

This gives:

• good high-speed top gear (11T)
• reasonable climbing ability (30T)
• tight enough spacing for cadence control

Ride feel

• smooth, fast shifting under load
• balanced cadence steps for road riding
• slightly harder climbing than 11–32 or 11–34 versions
• very efficient for endurance and racing

Best suited for

• Shimano 105 road bikes (R7000 groupset)
• endurance road cycling
• training and sport riding
• indoor trainers (very common choice)
• riders wanting a balanced gear range

Pros

• excellent Shimano shifting quality
• durable steel construction
• widely available and affordable
• smooth cadence transitions
• works with all Shimano 11-speed road drivetrains

Trade-offs

• not as easy climbing as 11–32 / 11–34
• heavier than Ultegra/Dura-Ace versions
• limited to Shimano HG 11-speed systems
• not suitable for MTB drivetrains

Bottom line

The Shimano CS-R7000 11-speed 11–30 cassette is a reliable, balanced road cycling cassette that delivers smooth Shimano 105 performance with a gear range suited to most flat-to-rolling road riding and moderate climbs.
