Crank Parts & Accessories – High-Quality Components for Optimal Power Transfer
If your crank is cranking – but not quite as it should...
Then it’s time for the right spare parts! While others are still debating whether mysterious bottom bracket creaks are due to the weather, age, or the neighbor, you know: only high-quality accessories will help here. Our extensive selection of crank parts and accessories transforms even the most stubborn drivetrain back into a smooth machine – whether for relaxed Sunday rides or intense training sessions.

Crank Arms – The Foundation for Efficient Power Transfer
High-quality crank arms transfer your pedaling force directly to the chainring. Replacement is recommended for visible cracks, worn pedal threads, or if you want to switch to a different crank length. Modern crank arms made of carbon or aluminum reduce weight and improve stiffness.
Crank Spindles – Precise Bearings for Smooth Operation
The crank spindle (bottom bracket) enables the smooth rotation of the crank within the frame. Signs for replacement include creaking while pedaling, play in the crank, or stiff rotation. High-quality crank spindles with ceramic bearings reduce friction losses and increase lifespan.
Crank Bolts & Pullers – Essential Installation Tools
Crank bolts secure the firm connection between crank arm and spindle. They should be checked regularly for correct torque and replaced immediately if damaged. Crank pullers are specialized tools for professional removal of crank arms without damaging components.
Spiders & Chainring Mounts – Modular Chainring Systems
Spiders often allow flexible chainring changes without removing the entire crank. Chainring mounts like direct mount or four-bolt setups provide various configuration options. Replacement is due in case of wear or desired gear ratio changes.
Power Meter Small Parts – Precise Performance Measurement
Modern power meter components require special small parts for installation and calibration. These include magnets, transmitter units, and mounting material. These items are essential for accurate watt measurement in professional training.
Crank Protection – Durability Through Impact Resistance
Crank protection elements shield expensive cranksets from scratches and impacts, especially for mountain biking or bike transport. Carbon cranks particularly benefit from this extra protection.
Preload Rings & Spacers – Fine-Tuning the Bearing Setup
Preload rings and spindle spacers allow precise adjustment of bearing play and chainline position. These small parts are crucial for optimal function and should be replaced at each bottom bracket service.
When is it time to replace crank parts?
- Wear: Visible signs of use, scratches, or deformation
- Performance upgrade: Weight reduction or improved stiffness
- Defects: Cracks, loose connections, or damaged threads
- System change: New gear ratios or compatibility with different components
- Maintenance intervals: Preventative replacement after recommended mileage
