Why Choose iGPSPORT CAD70

Cadence is one of the most important and undervalued metrics in cycling. Finding YOUR optimal cadence—the pedal speed that maximizes power with minimum fatigue—transforms your training and racing.

The CAD70 delivers cadence data to all your devices simultaneously, eliminating the need to choose between bike computers and apps. The 300-hour battery life means you install once and forget about it for months. The IPX7 waterproofing and anti-shock construction ensure reliable operation in real-world conditions.

At only 7.8 grams with three attachment straps, the CAD70 is genuinely invisible—you won't feel it pedaling, yet it captures every pedal stroke with professional-grade accuracy.

Understanding Cadence

What is Cadence?
Cadence is measured in RPM (revolutions per minute) and represents how many times per minute your pedals complete a full rotation.

Why Cadence Matters:

• Efficiency: Most cyclists have an optimal cadence for efficiency
• Fatigue: Higher cadence often means lower muscle fatigue
• Power: Optimal cadence maximizes sustainable power output
• Training: Cadence targets improve consistency and fitness
• Racing: Cadence awareness enables tactical pacing
• Recovery: Understanding your cadence prevents overexertion

Typical Cadence Ranges:

• Beginners: 60–80 RPM
• Recreational: 80–100 RPM
• Competitive: 90–120 RPM
• Track sprinters: 120–180+ RPM

How It Works

Installation (Takes 2 minutes):

1. Position CAD70 on your crank arm
2. Secure with appropriate silicone strap (3 styles included)
3. Pair via Bluetooth 5.0 or ANT+ with your device
4. Start recording cadence data immediately

Data Transmission:
The CAD70 detects crank rotations and broadcasts cadence in real-time to all paired devices. Whether you're using Garmin Edge, Wahoo ELEMNT, Zwift, or your smartphone, the sensor transmits simultaneously.

Battery Efficiency:
The low-power wireless protocol extends the CR2025 battery to an incredible 300 hours—over 12 days of continuous operation. In practical terms, expect 4–6 months of typical riding before battery replacement.

Dual-Mode Advantage

Why Bluetooth 5.0 AND ANT+?

Not all devices support the same protocol:

• Bluetooth 5.0: Smartphones, sports watches, fitness apps
• ANT+: Dedicated cycling computers (Garmin, Wahoo, iGPSPORT)

The CAD70's dual-mode design broadcasts to both simultaneously. Connect to your Garmin Edge AND your iPhone—both receive perfect cadence data with zero conflicts or interference.

Professional Accuracy

The high-sensitivity Hall-effect sensor measures pedal rotations with precision. Unlike estimates or calculations, the CAD70 provides real-time, accurate cadence detection:

• Instant acceleration/deceleration detection
• Accurate in all conditions (indoor, outdoor, terrain)
• No GPS smoothing or averaging
• Consistent across all bike types
• Perfect for structured training apps

Weather & Environmental Performance

Built for Real Conditions:

• Rain and wet riding: IPX7 rated
• Mud and grit: Sealed sensor design
• Temperature extremes: Durable polymer construction
• Salt spray (coastal): Corrosion-resistant materials
• High-speed wind: Minimal aerodynamic impact

Three Attachment Straps Included

The CAD70 comes with 3 different silicone straps to fit:

• Standard round crank arms – Most common
• Oval/flattened crank arms – Specialized designs
• Narrow crank arms – Road bike geometries

Choose the right strap for secure, tool-free mounting in seconds.
