Bottom Bracket Cartridge FUTURA SPURUS PRO 68 x 113 mm (FUT-WKS-113)

FUTURA SPURUS PRO bottom bracket cartridge, model FUT-WKS-113, is a sealed unit engineered for bicycles with a 68 mm shell and a 113 mm axle length. The cartridge design integrates a replaceable spindle and bearings to support pedal axle rotation and drivetrain function. It is intended for installations that match the 68 x 113 mm specification and for riders or technicians looking to maintain or restore smooth crank operation.

Advantages

The sealed cartridge construction reduces ingress of dirt and moisture, helping to extend bearing life and lower maintenance needs. A replaceable spindle and bearing set simplifies future servicing compared with non-serviceable units. The standardized shell width and axle length provide direct compatibility with frames requiring a 68 mm shell and 113 mm axle, enabling straightforward installation with standard tools. Materials and tolerances are designed to provide consistent rotation and support under normal cycling loads.

Suitable for

• Bicycles with a 68 mm bottom bracket shell requiring a 113 mm axle length
• Replacing worn or noisy bottom bracket cartridges
• Maintenance tasks where a sealed, replaceable spindle unit is preferred
• Road, commuter, and hybrid bikes with compatible drivetrain geometry

Key specifications

• Bottom bracket type: sealed cartridge unit with replaceable spindle and bearings
• Shell width compatibility: 68 mm
• Axle (spindle) length: 113 mm
• Designed for square taper or compatible crank interfaces (confirm exact crank interface before installation)
• Corrosion-resistant finish on exposed surfaces intended for long-term use

How to use

Prepare the bicycle by removing the crankset according to the crank manufacturer’s instructions and clean the bottom bracket shell. Inspect threads or press-fit surfaces for wear or damage and apply a light layer of grease or anti-seize to threaded interfaces if applicable. Install the cartridge into the shell, orienting it correctly for the drive and non-drive sides, and torque the unit to the frame manufacturer’s recommended specification. Refit the crankset, check chainline and pedal rotation, and perform a test ride to verify smooth operation.

Usage recommendations

Periodically check for play or roughness in the crank axle; if noise or lateral movement appears, replace the cartridge to avoid drivetrain wear. Use compatible tools and follow torque specifications to prevent damage to the cartridge or frame. For long-term reliability, avoid high-pressure wash directly into the bottom bracket area and perform routine drivetrain maintenance.
