Bike fit knowledge base

AI bike fitting can catch saddle height, knee angle, reach, and posture problems, but only if the photo setup is good. Here is what to trust and what to double-check.

Learn the signs of a saddle that is too high or too low, how knee angle changes, and how to check saddle height from a side-view photo.

Use shoulder width, riding style, and reach clues to choose a road bike handlebar width without guessing or copying pro setups.

Use one side-view photo to check your bike fit at home. Learn what AI can measure, how to take a good photo, and when to adjust saddle height or reach.

Use pro rider bike fit stats as a reference for geometry, reach, saddle height, knee angle, crank length, and bar drop without forcing an unsustainable race position.

Learn how to set the perfect saddle height for optimal power, comfort, and injury prevention. Includes the heel-to-pedal method, LeMond formula, and AI-powered analysis.

Knee pain is the most common cycling injury. Learn what causes it, how bike fit affects your knees, and how to fix it with proper saddle height and cleat positioning.

Learn how to perform a complete bike fit at home using proven methods and AI-powered tools. Save hundreds of dollars while getting a comfortable, efficient position.

Master the language of bike fitting with this complete glossary. Each term includes specific measurement ranges and how it affects your riding position.

Learn how to optimize your bike fit by calculating the ideal handlebar width and reach. Our interactive tool provides personalized recommendations that can improve your riding comfort and efficiency.

Handlebar width directly affects your comfort, aerodynamics, and control. Learn how to measure your AC joints, pick the right width for road, gravel, MTB, and TT bikes, and understand exactly when to go wider or narrower.

Choosing the right saddle for your road bike isn't just about comfort; it's about achieving peak performance and ensuring a ride that's both enjoyable and efficient. Learn how to find the perfect saddle for your riding style.

Female triathletes face unique challenges when fitting a triathlon bike. Differences in anatomy, including hip width, torso length, and shoulder width, require specific adjustments that standard bike setups often don't address. Learn how to optimize your tri bike fit for comfort, power, and faster transitions.

Women cyclists have different anatomical proportions than men, which affects optimal bike fit in significant ways. This guide provides specific measurements for saddle width, handlebar sizing, stem length, and angle targets to help female cyclists dial in their position.

Your first road bike won't fit perfectly out of the box. This guide covers frame sizing, the three essential adjustments every beginner should make, target angles for road bikes, and the most common fitting mistakes that cause pain.

Women's road bike fitting requires more than downsized men's geometry. Real differences in torso length, sit bone width, and shoulder width demand specific stem lengths (70-90mm), saddle widths (130-168mm), and handlebar sizing. Here are the actual numbers and angle targets.

In triathlon racing, transitions can make or break your performance. A well-optimized bike fit doesn't just improve your cycling speed—it sets you up for faster T1 and T2 transitions and helps you run better off the bike. Learn how to dial in your position for maximum transition efficiency.

The complete reference for road bike fit measurements — saddle height formulas, joint angle ranges, handlebar sizing, and a step-by-step order for dialing in your position.

Saddle angle is one of the most overlooked adjustments in bike fitting — and one of the easiest to get right. This guide covers exact angles for road, tri, and comfort positions, plus step-by-step instructions for twin-bolt and single-bolt seatposts.

Proper pedal and cleat positioning is one of the most overlooked aspects of triathlon bike fitting. Getting it right improves power transfer, reduces injury risk, and can even help your run performance. This guide covers fore-aft positioning, rotational angle, and stance width for optimal triathlon performance.

Cleat and pedal positioning on a mountain bike directly affects power, stability, and injury risk. This guide covers SPD cleat setup with specific measurements, flat pedal foot placement, and how to adjust for XC, trail, enduro, and downhill riding.

Foot position is one of the most overlooked parts of a bike fit, yet small changes at the cleat can fix knee pain, numbness, and power loss. This guide covers fore/aft placement, rotation, lateral position, wedges, and shims with specific measurements.

Every triathlon bike fit involves trade-offs between aerodynamic efficiency and sustainable comfort. The most aggressive position isn't always the fastest—finding your optimal balance depends on race distance, fitness level, and individual physiology. Learn how to dial in a position that's both fast and sustainable.

Every cyclist faces the same fundamental question when fitting their bike - how much comfort am I willing to trade for speed? The answer depends on your riding goals, physical capabilities, and how you want to spend your time on the bike. This guide helps you find your ideal balance point.
