The details that keep you moving
Performance is
a whole-bike story.
A thoughtful upgrade starts with your bike, your riding and your priorities. CeramicSpeed brings together ceramic bearings, oversized pulley systems and drivetrain care. At Mad Duck, we’ll help you decide where they fit into your build.
01 / Oversized Pulley Wheel Systems
A signature detail.
A technical purpose.
The OSPW is CeramicSpeed’s unmistakable rear-derailleur upgrade: larger pulleys paired with its ceramic bearings, designed around drivetrain efficiency.
The OSPW RS family adds an angular cage design and options including ALPHA Disc pulleys. Selected versions feature Active Debris Remover technology to help keep contamination away from the bearings.
Choose the system for your exact derailleur—not just its brand. Mounting interfaces, drivetrain generations and chain setup matter.
02 / ALPHA Wheel Bearings
Small components.
A considered upgrade.
ALPHA wheel bearings combine ceramic balls, hardened stainless-steel races and custom light-contact seals. The goal is low friction with protection for the riding ahead.
Wheel bearing upgrades begin with your hubs. We’ll help identify the correct bearing sizes and kit for your wheelset, then discuss installation and service.
03 / Bottom Brackets
Precision at the
heart of your bike.
Your bottom bracket connects the frame and crankset. Getting its standard, dimensions and fit right is the starting point for any upgrade.
Our CeramicSpeed catalog includes BB ALPHA options for different frame and crank combinations. Start with your setup, then let us help narrow the choice.
Examples: BSA / SRAM DUB Road · BB86 / Shimano Road. These are specific fitments, not universal replacements. Listed examples are special order; contact us for availability and delivery.
04 / UFO Drivetrain Care
Care is part of
the performance.
Great components deserve a good routine. The UFO family brings together chain lubrication, wax, cleaners and specialist care products. We’ll help you choose a routine that suits your conditions and how you like to maintain your bike.
Hand-built in Denmark
Quality begins
inside the bearing.
CeramicSpeed describes a hands-on process: bearings built in Denmark under clean-room conditions, with repeated inspection during assembly.
Carefully matched balls, cages and raceways are part of that attention to detail. It’s the kind of engineering that makes an upgrade interesting long before you see the finished bike.

Know the support
Warranty coverage varies by product. Review the current terms, registration requirements and care instructions for your chosen upgrade.
Your build. Your finishing touch.

detail count.
Keep it subtle or let the pulleys add a flash of color. Selected OSPW systems offer finish and color choices to complement a truly personal build.
