Lightweight ≠ compromise, exceptional stiffness & durability!
15% Stiffer, More Efficient!
Using one-piece molding technology, with no welding weaknesses, combined with a honeycomb torsion structure, effectively improves riding efficiency and stability!
XPOWER-S GEN2 Power Meter Spider
The XPOWER-S GEN2 power meter crankset offers ±1% power accuracy and provides four core cycling metrics, giving cyclists reliable data to better understand and improve their performance.
This power meter features an IP67 waterproof design, ensuring stable and reliable performance even in rainy and harsh riding conditions.

8 High-precision Strain Gauges
±1% Power Accuracy Output
Power measurement accuracy up to ±1%, providing stable and reliable data to support training and competition performance.
High-precision strain gauges and high-precision acceleration sensors, with a built-in intelligent temperature compensation algorithm, make it suitable for harsh weather and bumpy roads.

Four Core Cycling Data
Improve Cycling Performance Scientifically
1) Power - Precisely monitors output power with an accuracy of ±1%, making training intensity more controllable and scientific.
2) Cadence - Records pedaling frequency in real time, helping maintain stable and efficient cadence performance.
3) Left-Right Balance - Monitors the force distribution between both legs, identifies imbalances, and improves overall pedaling efficiency
4) Pedaling Smoothness - Analyzes the continuity of the entire pedaling cycle, making cycling smoother and less strenuous.

350-hour Long Battery Life
Single-port Blind-plug Magnetic Charging
The XPOWER-S GEN2 Power Meter Spider features a built-in lithium battery and uses a single-port blind-plug magnetic charging system, fully charging in just 3 hours and providing up to 350 hours of battery life.
Dual-protocol Connection
Seamless Data Synchronization
Supports ANT+ and BLE dual protocols.
Compatible with mainstream brand bike computers and smart bracelets on the market.
Stable connection and seamless data synchronization.
A Perfectly Matched Complete Set
The VENTUS carbon crank and the GEN2 XCADEY 5-BOLT power meter spider are designed as a complete system:
Plug-and-Play
No compatibility concerns, more stable and efficient
Factory-Tuned
Factory-designed as a set for more stable performance
Dual-BCD Ready
Supports 107/110/144 BCD, more flexible configuration
All-in-One Upgrade
A one-stop upgrade for easy installation and use
24mm Titanium Alloy Spindle, Balancing Strength And Broad Compatibility
Featuring a 24mm titanium alloy spindle, it balances high strength with lightweight performance.
Meeting mainstream road bike bottom bracket standards, allowing SHIMANO users to install it directly without needing to replace the bottom bracket, and it also supports large diameter bottom bracket systems such as T47 and BB386.
Please Note:
Because the current carbon crank is designed as “bare carbon” and there will be irregular lines when it is painted, these kinds of lines belong to the surface of the material and do not affect the strength and safety of use, so you can use it with confidence.
