Mountain bike GXP crankset with aluminium alloy hollow chainring and chromium molybdenum steel shaft
This crankset provides a direct fit replacement for mountain bikes using the GXP bottom bracket standard, compatible with frame shell widths from 68mm to 73mm. Its construction centres on two key materials: aluminium alloy 6061-T6 for the crank arms and integrated chainring, and chromium molybdenum steel for the central drive shaft. Available in three distinct colour finishes—black, red and purple—the component offers both functional replacement and visual customisation for riders looking to update their bike's drivetrain. The anodised surface treatment applied to the aluminium parts helps maintain their appearance against wear and environmental exposure.
Features and Construction
The crankset's design focuses on compatibility and material choice to suit mountain biking use. Its specifications are aimed at providing a reliable interface with existing 7-12 speed drivetrain systems from major manufacturers.
Material and Build
The crank arms and the hollow integrated chainring are made from aluminium alloy 6061-T6, a material known for its favourable strength-to-weight ratio in bicycle components. This aluminium structure is forged using a 3D process that creates a one-piece, integral unit, aiming to reduce potential weak points. The central shaft is constructed from chromium molybdenum steel, a material selected for its high tensile strength, resistance to deformation under load, and inherent corrosion resistance, which is important for a component exposed to trail conditions.
Size and Practical Fit
The crank arm length is 170mm, a common size for adult mountain bikes. The central shaft has a length of 118mm and an outer diameter of 24mm, designed to fit within the GXP bottom bracket system. The component supports axle widths from 68mm to 73mm, covering the standard range for most mountain bike frames. The pedal threads are standard M14, ensuring compatibility with the majority of mountain bike pedals on the market.
Uses and Placement
This crankset is intended as a replacement or upgrade part for mountain bicycles, particularly those used on trails, fire roads, or general off-road riding where reliable power transmission is needed.
Event or Professional Use
For riders participating in mountain bike events or regular trail riding, the compatibility with 7-12 speed systems from SHIMANO, SRAM, and others means it can integrate into existing gear setups. The availability of different chainring sizes—32T, 34T, 36T and 38T—allows gearing to be matched to specific course profiles or riding styles, from steep technical climbs to faster open sections.
Everyday Home Use
For the home mechanic or rider maintaining their own mountain bike, the GXP compatibility and clear size specifications (170mm arm length, 68-73mm shell width) simplify the selection process. The anodised finish on the aluminium components is intended to offer some protection against fading and minor scratches during cleaning and general use, helping the part retain its visual appeal as part of the bike's overall look.
Benefits and Buying Value
The value of this component lies in its direct compatibility, material specification, and range of sizing options, offering a practical solution for drivetrain updates or replacements.
Reuse and Low Maintenance
The materials chosen—aluminium alloy and chromium molybdenum steel—are standard in bicycle componentry for their balance of performance and longevity. The anodised surface treatment on the aluminium is a common industrial process that provides a harder, more wear-resistant outer layer than bare metal, which can help maintain the component's appearance with routine cleaning. No specialist maintenance beyond standard bicycle care is indicated by the source material.
Why Choose This Product
This crankset offers a defined set of specifications: GXP compatibility, a 170mm arm length, a choice of four chainring sizes, and three colour finishes. For a rider whose bike uses the GXP bottom bracket standard and who needs a replacement or wishes to change their gearing, these concrete options provide a clear match. The stated compatibility with 7-12 speed systems from major manufacturers reduces uncertainty about whether the part will work with existing shifters, derailleurs, and chains.
