Bicycle Repair Course

Lesson 1 • Braking System Components

Identifies rim, disc, and coaster brake types along with levers and cables. Provides context for brake repair chapters that follow.

Lesson 2 • Cockpit and Contact Points

Covers handlebars, stem, saddle, seatpost, and pedals. These components directly affect rider fit and are frequently adjusted during service.

Lesson 3 • Drivetrain Components Overview

Introduces cranks, chainrings, chain, cassette, and derailleurs. Understanding drivetrain layout is essential before performing adjustments or replacements.

Lesson 4 • Bicycle Frame and Fork Basics

Covers frame geometry, materials, and fork types. Establishes the structural vocabulary needed for all subsequent repair tasks.

Lesson 1 • Personal Safety and Shop Practices

Covers eye protection, glove use, chemical handling, and lifting technique. Safe habits prevent injuries that interrupt learning and professional work.

Lesson 2 • Essential Hand Tools

Covers hex keys, screwdrivers, cone wrenches, and torque wrenches. Correct tool selection is the first step in every repair procedure.

Lesson 3 • Repair Stand and Workspace Setup

Explains stand types, clamping positions, and bench organization. A stable, well-lit workspace reduces errors and speeds up every repair.

Lesson 4 • Lubricants, Cleaners, and Consumables

Distinguishes wet, dry, and ceramic lubricants from degreasers and greases. Applying the right product to the right part extends component life.

Lesson 1 • Tube Removal and Flat Diagnosis

Teaches tire lever technique, tube extraction, and puncture location methods. Accurate diagnosis prevents repeat flats after repair.

Lesson 2 • Tire Selection and Condition Assessment

Covers tread wear indicators, sidewall damage, and tire sizing compatibility. Selecting the correct replacement tire prevents handling and safety issues.

Lesson 3 • Removing and Installing Wheels

Covers quick-release, thru-axle, and bolt-on wheel removal. Proper wheel removal is the prerequisite for every tire and tube service task.

Lesson 4 • Tubeless Tire Setup and Repair

Explains rim tape, valves, sealant installation, and on-road tubeless repair. Tubeless systems are increasingly common on modern road and mountain bikes.

Lesson 1 • Mechanical Disc Brake Service

Explains rotor alignment, pad clearance, and cable actuation adjustment for mechanical disc brakes. Mechanical discs require precise caliper positioning for consistent performance.

Lesson 2 • Rim Brake Adjustment

Covers pad alignment, centering, cable tension, and reach adjustment for caliper and V-brakes. Correct rim brake setup eliminates rubbing and ensures full stopping power.

Lesson 3 • Disc Rotor Inspection and Replacement

Addresses rotor thickness measurement, warping diagnosis, and rotor replacement. Worn or warped rotors compromise braking and must be replaced before pad service.

Lesson 4 • Rim Brake Pad and Cable Replacement

Teaches pad wear assessment, pad replacement, and full cable and housing replacement. Fresh cables and pads restore braking performance on worn systems.

Lesson 1 • Drivetrain Cleaning Procedures

Covers chain cleaning tools, degreaser application, cassette scrubbing, and chainring cleaning. A clean drivetrain is the prerequisite for accurate adjustment.

Lesson 2 • Rear Derailleur Adjustment

Explains limit screw function, B-tension setting, and cable tension adjustment for precise rear shifting. Systematic adjustment eliminates ghost shifting and missed gears.

Lesson 3 • Front Derailleur Adjustment

Covers height, rotation, limit screws, and cable tension for front derailleurs. Proper front derailleur setup prevents chain drop and ensures clean cross-gear shifts.

Lesson 4 • Chain Inspection and Replacement

Teaches chain wear measurement, master link use, and chain sizing. Replacing a worn chain before it damages the cassette saves significant repair costs.

Lesson 1 • Lateral and Radial Truing Technique

Covers incremental spoke adjustments to correct side-to-side and up-down wobble. Systematic small corrections prevent over-tensioning and spoke fatigue.

Lesson 2 • Cartridge Bearing Hub Service

Teaches cartridge bearing removal, press-fit installation, and play diagnosis. Cartridge hubs require different tools and techniques than cup-and-cone systems.

Lesson 3 • Spoke Replacement

Explains spoke length calculation, lacing patterns, and single spoke replacement. Replacing a broken spoke restores wheel integrity and prevents further damage.

Lesson 4 • Wheel Truing Fundamentals

Introduces truing stand use, spoke tension concepts, and lateral versus radial deviation. Understanding spoke mechanics is essential before making any tension adjustments.

Lesson 1 • Headset Types and Inspection

Distinguishes threaded, threadless, and integrated headsets and explains play and bearing wear diagnosis. Identifying headset type determines the correct service procedure.

Lesson 2 • Stem Installation and Adjustment

Covers quill stem and ahead stem installation, height adjustment, and alignment. Stem position affects both handling and rider comfort.

Lesson 3 • Threaded Headset Service

Explains locknut and adjustable cup adjustment using headset wrenches. Threaded headsets require simultaneous wrench technique to hold adjustment while locking.

Lesson 4 • Handlebar Installation and Tape

Teaches handlebar clamp torque, bar end plug installation, and bar tape wrapping technique. Properly wrapped bars improve grip comfort and complete a professional service.

Lesson 1 • Crankset Removal and Installation

Covers two-piece, three-piece, and self-extracting crank removal and installation procedures. Correct spindle engagement depth is critical for bearing preload and crank retention.

Lesson 2 • Pedal Removal and Installation

Teaches thread direction, pedal wrench technique, and grease application for pedal service. Pedal threads are frequently cross-threaded by technicians who ignore thread direction.

Lesson 3 • Threaded Bottom Bracket Removal and Install

Covers correct tool selection, drive-side reverse thread, and torque specifications for threaded BBs. Reverse threading on the drive side is a common source of installation errors.

Lesson 4 • Bottom Bracket Standards Overview

Identifies threaded, press-fit, and T47 bottom bracket standards and their compatibility requirements. Knowing the standard prevents tool damage and incorrect part selection.
