Bottom Bracket Cartridge FUTURA SPURUS PRO 68 x 129 mm (FUT-WKS-129)

Cartridge bottom bracket FUTURA SPURUS PRO 68 x 129 mm is a sealed-unit bottom bracket designed to provide smooth rotation and straightforward service for bicycles with a 68 mm shell. The unit integrates bearings and spindle into a single replaceable cartridge, reducing maintenance compared with cup-and-cone assemblies. It is intended for frames with a 68 mm bottom bracket shell and cranksets that require a 129 mm spindle length.

Advantages

The sealed cartridge construction keeps grease in and contaminants out, improving bearing life and reducing the need for frequent maintenance. A factory-assembled spindle and bearing unit simplifies installation and replacement, saving time during service. The standardized dimensions ensure compatibility with typical English-threaded or press-fit adapters for 68 mm shells, providing reliable fit and stable crankset support.

Suitable for

• Bicycles with a 68 mm bottom bracket shell
• Cranksets requiring a 129 mm spindle length
• Commuter, trekking and recreational bikes where low-maintenance components are preferred
• Workshops and home mechanics needing a straightforward replacement unit

Key specifications

• Bottom bracket type: sealed cartridge unit
• Shell width compatibility: 68 mm
• Spindle (axle) length: 129 mm
• Assembly: integrated spindle and bearings, pre-greased
• Intended use: standard square-taper or compatible crank interfaces (check crank compatibility)

How to use

Ensure the bicycle frame’s bottom bracket shell is clean and free of debris. Confirm that the crankset is compatible with a 129 mm spindle length and that any necessary adapters or spacers are prepared. Remove the old bottom bracket following manufacturer procedures, fit the sealed cartridge into the shell, and tighten to the frame manufacturer’s torque specifications. Reinstall the crankset and check for correct chainline and smooth rotation; re-torque fasteners after a short test ride if required.

Usage recommendations

For reliable performance, use suitable thread lubricant or anti-seize where threads are present, and follow frame and crankset torque specifications. Periodically inspect for play or unusual noise and replace the cartridge unit if signs of bearing wear appear. Store and install the unit in a dry environment to preserve seals and pre-applied grease.
