Design and build bicycle wheels


Application

This unit describes the performance outcomes required to design and build bicycle wheels with different hub, spoke and rim configurations. It involves preparing for the work, selecting and using specialist tools and equipment to design and carry out the building and testing of bicycle wheels, and completing workplace processes and documentation.

It applies to those working in the bicycle retail, service and repair industry.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

Elements

Elements describe the essential outcomes.

Performance Criteria

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section.

1. Prepare to design and build bicycle wheels

1.1 Job requirements are determined from workplace instructions, including wheel materials, components and spoke patterns

1.2 Bicycle wheel design requirements and manufacturer specifications are researched and interpreted

1.3 Bicycle wheel design and specifications are confirmed with customer

2. Prepare to build bicycle wheels

2.1 Wheel components are checked against specifications and inspected for quality prior to build

2.2 Bicycle build is planned, including build sequence and post-build testing process, to use time efficiently

2.3 Hazards associated with the work are identified and risks are managed

2.4 Tools and equipment, including personal protective equipment (PPE), are selected and checked for serviceability

2.5 Work area and wheels, components and materials are prepared

3. Build and test bicycle wheels

3.1 Bicycle wheels are built according to job and customer requirements, work plan, and safety and environmental requirements

3.2 Bicycle wheel hubs and rims are selected and spoke lengths calculated

3.3 Bicycle wheel spokes are laced and tensioned according to manufacturer specifications and workplace instructions

3.4 Built bicycle wheels are checked for symmetry and tested for trueness against specifications

3.5 Results and quality issues are reported to authorised personnel as required

4. Complete work processes

4.1 Final inspection is made to ensure work meets workplace expectations and bicycle is presented ready for use

4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected and stored

4.3 Tools and equipment are checked, reported if faulty, and stored according to workplace procedures

4.4 Workplace documentation is processed according to workplace procedures

Evidence of Performance

Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in this unit’s elements, performance criteria, range of conditions and foundation skills:

lacing a 32 hole three-cross spoke pattern

disc and non-disc brake specific patterns.


Evidence of Knowledge

Individuals must be able to demonstrate knowledge of:

work health and safety (WHS) and occupational health and safety (OHS) requirements relating to designing and building bicycle wheels, including procedures for:

manually handling bicycle wheels

identifying workplace hazards

using tools and equipment, including personal protective equipment (PPE)

environmental requirements, including procedures for disposing of waste materials

key bicycle terminology relating to wheel build for different bicycle types

key features to be considered in wheel design:

hubs, spoke and rim selection

32 hole three-cross spoke pattern

disc and non-disc brake specific patterns

symmetrical and asymmetrical patterns

wheel dynamics and loading

wheel and hub mechanical principles

bicycle wheel components specified in the range of conditions and their specifications

types and use of tools and equipment used to design and build bicycle wheels

techniques for designing and building bicycle wheels, including:

material used in bicycle wheels

lacing and spoke pattern

calculating spoke lengths

assembly, truing and tensioning of wheels

symmetrical and asymmetrical patterns of wheels

wheel dynamics and loading

torque measurement and adjustment of wheels

wheel and hub testing procedures.


Assessment Conditions

Assessors must satisfy NVR/AQTF assessor requirements.

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the bicycle wheels they have designed and built, e.g. build orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

bicycle workplace or simulated workplace

workplace instructions detailing job requirements

manufacturer and technical bicycle wheel specifications

PPE required to design and build bicycle wheels

wheel components specified in the range of conditions

three different bicycle wheels as specified in the performance evidence requiring a complete build

tools and equipment appropriate for designing and building bicycle wheels.
