Fit Bike Co Crank Spindle 24mm 48 Spline

Fit Bike Co Crank Spindle 24mm 48 Spline 

Product Description

Overview

The Fit Bike Co 24mm crank spindle is a replacement spindle for 48-spline cranksets. Constructed from hollow chromoly for a balance of strength and reduced weight, this spindle is designed to handle the demands of modern BMX riding. Bolts are sold separately and must be purchased to complete installation.

Key Features

• Hollow chromoly construction – CrMo material provides high tensile strength while hollow design reduces overall weight compared to solid spindles
• 48-spline interface – Industry-standard spline count ensures secure engagement between spindle and crank arms, preventing slippage under load
• 24mm diameter – Standard BMX spindle size fits most modern mid and Spanish bottom bracket systems
• Replacement spindle – Allows riders to replace damaged or worn spindles without purchasing an entirely new crankset

Technical Specifications

• Material: Hollow chromoly (CrMo)
• Diameter: 24mm
• Spline count: 48 spline
• Bolts: Sold separately (not included)

Compatibility and Ideal Use Cases

This spindle is compatible with Fit Bike Co and other cranksets that use a 24mm, 48-spline interface. Verify your crankset's spindle diameter and spline count before ordering—some cranks use 22mm, 19mm, or different spline configurations. Fits frames with mid or Spanish bottom bracket shells designed for 24mm spindles. Remember to order compatible crank bolts separately as they are required for installation but not included. Ideal for riders needing to replace a bent, damaged, or stripped spindle, or those upgrading from a heavier solid spindle to reduce rotating weight.
