BIGROCK GEN3 + P1
A New Generation Lightweight Performance Drivetrain System
Modern road cyclists are no longer simply chasing lower weight.
A true high-performance drivetrain system must also deliver:
• Higher stiffness
• More direct power transfer
• Accurate riding data
• Long-term durability
• Clean integrated aesthetics
The BIGROCK GEN3 Carbon Crankset and P1 Power Meter System were developed around these exact goals.
By combining advanced carbon fiber engineering, a 24mm titanium spindle platform, and integrated power measurement technology, BIGROCK is redefining the performance limits of lightweight road bike drivetrains.
Carbon Fiber Engineering
The GEN3 crank platform uses a high-stiffness carbon fiber layup structure optimized for:
• Sprinting
• Climbing
• High-cadence riding
• Long-distance endurance riding
Compared with traditional alloy cranksets, the carbon structure significantly reduces rotational weight while maintaining exceptional rigidity under high power output.
Laboratory testing data includes:
• 820,000 fatigue cycles tested
• 180kg high-load fatigue testing
• 35% higher stiffness compared with similar products
• ISO fatigue standard verification
BIGROCK is not focused on lightweight numbers alone.
The goal is to achieve maximum drivetrain efficiency through advanced engineering and structural optimization.
24mm Titanium Spindle System
At the core of the GEN3 platform is BIGROCK’s precision-machined 24mm titanium spindle system.
Compared with conventional steel spindle systems, titanium technology delivers:
• Lower overall weight
• Higher stiffness-to-weight ratio
• Better fatigue resistance
• Faster acceleration response
The spindle system has also completed over 2 million durability cycles without structural cracking or damage.
Combined with the carbon crank arms, the system creates a more direct, refined, and responsive riding experience.
P1 Integrated Power Meter System
The P1 Power Meter System is designed for modern performance-focused road cycling.
Core specifications include:
• Power measurement range: 0–2200W
• Cadence range: 30–180RPM
• Accuracy: ±1%
• ANT+ & Bluetooth connectivity
• IP68 waterproof rating
• USB magnetic charging
• Up to 260 hours battery life
The system supports:
• Real-time power data
• Cadence tracking
• Left-right balance analysis
• Pedaling smoothness analysis
Compatible with major cycling computers including:
• Garmin
• Wahoo
• Bryton
• iGPSPORT
• COROS
• CYCPLUS
Built for Modern Road Bikes
The BIGROCK GEN3 + P1 platform is compatible with:
• Shimano road drivetrains
• SRAM road drivetrains
• EASTON Direct Mount interfaces
Ideal for:
• Lightweight climbing bikes
• Aero race bikes
• Endurance road builds
• High-performance integrated setups
For riders upgrading from standard Shimano 105-level cranksets, the BIGROCK system can significantly reduce drivetrain weight while improving overall ride responsiveness and efficiency.
More Than Lightweight
BIGROCK is not simply about reducing weight.
Through:
• Carbon fiber structural engineering
• Precision titanium machining
• Integrated power measurement technology
• Laboratory-grade fatigue testing
BIGROCK creates a complete drivetrain platform designed for serious road cyclists and performance enthusiasts.
More than just a crankset.
More than just a power meter.
A complete lightweight performance drivetrain ecosystem.
