Detailed Information:

Axle Type: Cotterless Square Nut Style
The Cotterless Bottom Bracket (B.B) Axle features a square taper interface. This is a common design in bicycles where the crank arms attach to the axle using a square taper fit. This system allows for efficient power transfer from the rider’s legs to the bike’s drivetrain.
Left Side Length: 32mm
The left side of the axle, measuring 32mm, is designed to fit the left crank arm. This ensures that the arm sits securely and operates smoothly, with enough length to handle the pressure from pedaling without shifting.
Center Length: 52mm
The center section, at 52mm, is the part of the axle that sits within the bottom bracket shell of the bike. It is designed to fit standard shell widths while ensuring the axle is well-supported and rotates efficiently.
Right Side Length: 35mm
The right side of the axle, slightly longer at 35mm, allows for correct positioning and attachment of the right crank arm. This slight length difference ensures balanced power distribution between both crank arms.
Axle Length: 119mm
The total axle length of 119mm is suitable for a wide range of bicycles that use a square taper bottom bracket system. This length is typically used in road bikes, mountain bikes, and hybrid bicycles.
Overall Length: 140mm
Including the taper ends and thread sections, the total length is 140mm, which offers plenty of room for secure attachment using nuts and ensures proper function within the bottom bracket shell.
Style: Nut Style
The axle uses a nut fastening system, which is common for older or more traditional square taper systems. This setup is straightforward, offering ease of installation and ensuring a secure connection between the crank arms and axle.
Material: Steel
Constructed from high-strength steel, the axle is built for durability and longevity. Steel offers excellent resistance to deformation under load and wear from regular riding.
Color: Black
The black finish provides a sleek, minimalistic look that matches well with most bike frames. The color is also corrosion-resistant, ensuring that the axle remains protected against the elements.
Brand: AltaLine
AltaLine is a trusted name in bicycle components, known for producing reliable, high-quality parts for various types of bikes. Their bottom bracket axles are engineered for strength and precision.

Key Factors to Check for Compatibility:

Bottom Bracket Shell Width: Ensure the bike’s bottom bracket shell width matches the 68mm standard, as this axle length is designed for that shell size.
Square Taper Crankset: The crankset should be square taper, as this axle works with this type of crank interface.
Frame and Chainline Requirements: Depending on the bike’s frame geometry and chainline needs, 119mm may be the appropriate length. Verify the axle length in relation to the bike’s chainline for proper gear shifting.
