Mountain bike GXP crank set with hollow integrated aluminium alloy tooth plate and central shaft, 170mm leg length compatible with 7-12 speed systems, available in black, red or purple colours with 32T, 34T or 36T chain ring options
GXP-compatible mountain bike crank set with aluminium alloy tooth plate and chromium molybdenum steel shaft

This mountain bike crank set provides a lightweight yet durable solution for riders seeking compatibility with multiple drivetrain systems. Constructed from 6061-T6 aluminium alloy using integral forging techniques, the hollow integrated tooth plate maintains structural integrity while reducing weight. Paired with a chromium molybdenum steel central shaft, the combination delivers strength where needed most while resisting corrosion and high temperatures. Available in multiple colour options and chain ring sizes, this crank set offers flexibility for different riding preferences and bicycle specifications.
Features and Construction

The crank set combines material strengths through specialised manufacturing processes to create a balanced component suitable for demanding mountain biking applications. Each element serves a specific purpose, from the lightweight aluminium alloy tooth plate to the robust steel central shaft, working together to transfer pedal power efficiently.
Material and Build
Constructed from 6061-T6 aluminium alloy, the hollow integrated tooth plate benefits from this material's favourable strength-to-weight ratio. The 3D forging process creates integral moulding without weak points or joins that could compromise durability. The chromium molybdenum steel central shaft adds strength where torque forces concentrate, while its corrosion resistance helps maintain performance in various weather conditions. Anodic oxidation surface treatment provides colour retention, with laser treatment preventing fading over time.
Size and Practical Fit
With a 170mm leg length and 118mm shaft length, this crank set suits riders across different height ranges and riding styles. The 24mm outer diameter shaft works with bottom brackets supporting 68-73mm widths, covering common mountain bike specifications. M14 pedal threads accommodate standard mountain bike pedals, while the chain ring options ranging from 32T to 38T teeth allow gearing customisation based on terrain and riding preferences.
Uses and Placement

Designed specifically for mountain bike applications, this crank set addresses the demands of off-road riding where components face varied terrain, weather conditions and impact forces. Its compatibility with multiple drivetrain systems makes it suitable for different bicycle configurations and upgrade scenarios.
Event or Professional Use
For competitive mountain biking or demanding trail riding, the crank set's material combination offers reliability under pressure. The chromium molybdenum steel shaft withstands high torque situations common during technical climbs and rapid acceleration, while the aluminium alloy tooth plate reduces rotational mass for quicker response. Compatibility with 7-12 speed systems allows integration with both mid-range and higher-end drivetrain components used in competitive settings.
Everyday Home Use
For recreational mountain bikers and commuters using off-road capable bicycles, this crank set provides durable performance with straightforward compatibility. The GXP installation type works with common bottom bracket standards, simplifying replacement or upgrade processes. The anodised oxidation surface treatment helps maintain appearance with regular cleaning, while the corrosion-resistant materials reduce maintenance requirements for bicycles stored in varied conditions.
Benefits and Buying Value

This crank set combines specific material properties and manufacturing techniques to deliver functional advantages for mountain bike riders. Each design element addresses practical considerations rather than relying on generic claims about quality or performance.
Reuse and Low Maintenance
The corrosion-resistant chromium molybdenum steel shaft and anodised aluminium surfaces reduce maintenance requirements compared to untreated components. The laser surface treatment specifically addresses colour retention, preventing fading that can occur with standard finishes. This combination allows the crank set to maintain its appearance and function over extended periods with basic cleaning and lubrication maintenance.
Why Choose This Product
This crank set offers specific compatibility advantages through its GXP installation type and broad drivetrain support. The measurable specifications—170mm leg length, 118mm shaft length, 68-73mm bottom bracket compatibility—provide clear fit guidance rather than vague claims. The material combination addresses both weight reduction through aluminium alloy and strength through chromium molybdenum steel, creating a balanced component suitable for mountain biking's varied demands.
