Bike Fit Optimization

Bike Fit Optimization

Proper bike fit maximizes power output, improves aerodynamics, and prevents injury - data-driven fitting combines biomechanics with performance metrics.

Key Fit Measurements

• Saddle height: Affects power output and knee angle
• Saddle fore/aft: Impacts hip angle and weight distribution
• Handlebar reach: Determines aero position and comfort
• Handlebar drop: Affects aerodynamics and breathing
• Cleat position: Influences power transfer and knee tracking

Power-Based Fit Validation

• Test FTP at different saddle heights
• Measure power output in various positions
• Compare aerodynamics vs power trade-offs
• Assess comfort on long rides (3+ hours)

Common Fit Issues

• Saddle too high: Hip rocking, hamstring strain, reduced power
• Saddle too low: Quad dominance, knee pain, reduced efficiency
• Reach too long: Back pain, difficult to breathe, unsustainable aero
• Reach too short: Poor aerodynamics, cramped position

Time Trial vs Road Bike Fit

TT bikes allow more aggressive positions with base bars and clip-on extensions. Road bikes require compromise between climbing position (upright, hands on hoods) and aero position (drops, elbows in). Most riders need different fits for different race types.
