Function Description

The FUNN Black Magic Pedals are bicycle pedals intended to provide a secure and efficient connection between the rider's feet and the bicycle's crankset. They are designed to offer adjustable grip and are built for durability, with provisions for maintenance and replacement of wear parts. The pedals facilitate power transfer from the rider to the drivetrain, enabling propulsion of the bicycle.

Important Technical Specifications

Tools Required for Installation:

Hex key 6mm
Socket wrench 4mm

Contents:

Pedals: 1 SET
Socket wrench 4mm: 1 PC (This implies a 4mm socket wrench is included with the pedals, likely for grip pin maintenance).

Installation Torque Specification:

Axle tightening: 34 Nm (300 lb-in) using a 6mm hex key.

Grip Pin Specifications:

Removal/replacement tool: 4mm socket wrench.
The manual illustrates "NEW PINS" and "DAMAGED PINS," indicating that the pins are replaceable and crucial for optimal grip.

Axle Identification:

Left pedal: Features a single indented line surrounding the spindle for easy identification.
Right pedal: Lacks the indented line.

Usage Features

Pedal Identification: The manual provides clear instructions on how to differentiate between the left and right pedals. The left pedal is marked with a single indented line around its spindle, while the right pedal does not have this marking. This is crucial for correct installation, as bicycle pedals typically have opposing thread directions (left pedal is reverse-threaded, right pedal is standard-threaded).

Installation Process:

Identification: First, the user must identify the left and right pedals based on the spindle marking.
Lubrication: The axle thread should be lightly lubricated with grease before installation to ensure smooth threading and prevent seizing.
Initial Threading: The axle is initially threaded into the crank hole by hand. This step helps prevent cross-threading, which can damage both the pedal and the crank arm.
Tightening: A 6mm hex key is used to tighten the screw to the specified torque of 34 Nm (300 lb-in). The manual explicitly warns against excessive force to prevent damage. The illustrations clearly show the direction of tightening for both left and right pedals, indicating that the left pedal is tightened counter-clockwise and the right pedal is tightened clockwise when viewed from the side of the pedal.

Grip Customization and Maintenance: The pedals feature replaceable grip pins, allowing users to fine-tune the level of grip according to their preference or riding conditions. A 4mm socket wrench is used for removing and replacing these pins. The manual advises replacing damaged or worn pins to ensure safe riding, illustrating the difference between new and damaged pins. This feature enhances the longevity and performance of the pedals by allowing for targeted replacement of wear parts.

Maintenance Features

The manual outlines a comprehensive maintenance schedule and indicators for when servicing is required, ensuring the longevity and safe operation of the pedals.

Indicators for Servicing: Pedals should be serviced if any of the following conditions are observed:

Noise: The pedal emits noise during rotation. This could indicate issues with the bearings or other internal components.
Rough Rotation: The pedal feels rough when rotated by hand. This is a strong indicator of bearing wear or contamination.
Play in Bearings: There is noticeable looseness or "play" in the bearings, which can lead to inefficient power transfer and potential failure.

Recommended Maintenance Schedule:

Bearing Cleaning and Regreasing: Bearings should be cleaned and regreased at least once every 12 months.
Increased Frequency for Wet Conditions: If riding predominantly in wet conditions, this interval should be shortened to at least once every 6 months. This is crucial as moisture can accelerate bearing wear and corrosion.
Bearing Replacement: Damaged bearings should be replaced immediately to prevent further damage to the pedal and ensure safe operation.

Structural Integrity:

Pedal Replacement: The manual explicitly states that pedals with fractures in the body should be replaced. This is a critical safety instruction, as a fractured pedal body can fail catastrophically during use, leading to serious injury.

Overall, the FUNN Black Magic Pedals are designed with both performance and maintainability in mind, offering features that allow for user customization, straightforward installation, and a clear maintenance regimen to ensure a long and safe service life.
