Track Bikes
Track bikes are highly specialized racing machines designed exclusively for use on velodromes. Unlike conventional racing bikes, they dispense with any unnecessary components and follow a clear principle: maximum speed at minimum weight.
Basic Properties of Track Bikes
Track bikes differ fundamentally from road racing bikes through their extreme specialization for track use. The most important feature is the fixed gear, where the cranks are rigidly connected to the rear wheel – a freewheel does not exist.
Core Features Overview
- Fixed Drive: No gears, no freewheel
- No Brakes: Speed control is achieved exclusively through the legs
- Minimal Weight: Typically 6-7 kg for sprint track bikes
- Aggressive Geometry: Steep angles for maximum power transfer
- High-Quality Materials: Carbon, aluminum or innovative composite materials
UCI Regulations
Track bikes must meet strict UCI requirements: Minimum weight 6.8 kg, maximum frame height, no aerodynamic add-ons outside defined areas. Before competitions, all bikes are inspected.
Technical Construction and Components
The construction of a track bike follows strict functional and regulatory requirements. Every component is designed to enable maximum performance at minimum air resistance.
Frame and Geometry
Track bike frames feature extremely steep geometry that differs significantly from road racing bikes. The head angle is typically 74-75 degrees, the seat angle at 75-76 degrees. This geometry enables an aggressive riding position and optimal power transfer to the pedals.

Wheels and Aerodynamics
Track bike wheels are the heart of aerodynamic performance. Depending on the discipline, different wheel types are used:
Sprint Disciplines:
- Front wheel: 3-5 spokes or disc wheel
- Rear wheel: Full disc wheel
- Rim depth: 80-90mm front, full disc rear
- Weight: Minimization is secondary, aerodynamics primary
Endurance Disciplines:
- Front wheel: 60-80mm deep-section rim
- Rear wheel: 80-90mm deep-section rim or disc
- Spoke count: 16-24 spokes with aerodynamic profile
- Weight: Compromise between aerodynamics and acceleration
Drive and Gear Ratio
The drive of a track bike is designed for maximum efficiency. The choice of gear ratio is crucial for performance in different disciplines.
Typical Gear Ratios by Discipline:
Chain Tension and Maintenance:
The chain must be extremely tight to prevent skipping under enormous forces. The chain line must be perfectly aligned – even minimal deviations lead to power loss and increased wear.
Special Features and Adjustments
UCI Regulations and Material Restrictions
The UCI regulations set strict requirements for track bikes to ensure equal opportunities. These special requirements affect all aspects of bike construction:
UCI Checklist for Track Bikes:
- Minimum weight 6.8 kg for the complete bike
- Maximum frame height based on body height
- No freewheel, only fixed gear allowed
- No brakes (except in mass-start races for safety)
- Symmetric frame shape without extreme aerodynamic elements
- Handlebar maximum 75cm wide
- Saddle height no more than 5cm above bottom bracket axis
- Pedal plates only in defined area
Violations of UCI material rules lead to immediate disqualification. At world championships and Olympic Games, all bikes are technically inspected and measured before the race.
Seating Position and Bike Fitting
The seating position on a track bike is significantly more aggressive than on a road racing bike. The upper body is strongly inclined forward, the arms are almost extended. This position minimizes air resistance and enables maximum power transfer.
Position Differences by Discipline:
- Sprint Disciplines:
- Extremely low upper body
- Elbows close to body
- Saddle far back for maximum power development
- Handlebar low and narrow
- Endurance Disciplines:
- Somewhat more upright for longer loads
- Wider handlebar position for better breathing
- Saddle slightly further forward for efficient sustained power
- Compromise between aerodynamics and comfort
Professional bike fitting is essential for track cyclists. Even a 5mm difference in saddle height can affect performance by 2-3% – in sprint disciplines the difference between victory and defeat.
Maintenance and Care
Track bikes require meticulous maintenance to maintain extreme precision. The lack of gears and brakes simplifies some aspects, but the requirements for chain tension and bearing quality are higher.
Regular Maintenance Tasks
Before Each Training/Race:
- Check and adjust chain tension
- Check tire pressure (Sprint: 10-12 bar, Endurance: 9-11 bar)
- Check bearings for play (bottom bracket, headset, hubs)
- Check saddle and handlebar fastening
- Check pedal cleats for secure fit
Weekly:
- Clean and oil chain
- Inspect frame for cracks
- Center wheels and check spoke tension
- Check contact points (saddle, handlebar tape) for wear
Monthly:
- Grease bearings (bottom bracket, headset)
- Measure chain and sprocket for wear
- Check entire system for fastenings
- Professional inspection under high load
Training with Track Bikes
Training on the track requires special techniques and skills. The lack of a freewheel means the legs must constantly be in motion – a fundamental difference from road cycling.
Getting Started in Track Cycling
For beginners in track cycling, getting used to the fixed gear is the biggest challenge. The following progression has proven effective:
Learning Phases for Track Bike Newcomers:
- Phase 1 (Weeks 1-2): Basics
- Riding on straight sections
- Controlled braking with legs
- Safe mounting and dismounting
- Phase 2 (Weeks 3-4): Cornering Technique
- Slow cornering
- Maintaining balance in lean
- Speed control in corners
- Phase 3 (Weeks 5-8): Advanced Techniques
- Higher speeds
- Precise riding in banking
- Group riding and position battles
- Phase 4 (from Week 9): Competition Preparation
- Race simulations
- Sprint and endurance units
- Tactical training
Specific Training Units
Sprint Training on the Track:
- Flying 200m sprints (maximum power)
- Standing starts for acceleration
- Keirin simulations with progressive speed
- Match sprints for tactical understanding
Endurance Training on the Track:
- Longer tempo series (4-10 minutes)
- Pursuit simulations with constant power

- Points race for alternating loads
Costs and Investment
Purchasing a track bike is a significant investment. Prices vary greatly depending on quality level and specialization.
Investment Levels for Different Requirements:
Additional Costs to Consider:
- Spare parts and wear: 500-1,000 € per year
- Track membership: 200-800 € annually
- Coach support: 0-3,000 € per year
- Travel to competitions: 1,000-5,000 € per year
Differences from Other Cycling Categories
Track bikes differ fundamentally from all other bicycle types in cycling. These differences are not only technical but also practical in nature.
