A precision professional bike fit is a comprehensive process that goes beyond basic sizing to ensure that your bike is perfectly tailored to your body, riding style, and performance goals. It involves a detailed, scientific approach using advanced technology and the expertise of a trained fitter. The specifics of a bike fit can vary by provider but here's what you could expect from a full, comprehensive professional bike fit:

Initial Consultation

• Discussion of Goals: The fitting session typically starts with a conversation where the fitter will ask about your riding habits, goals, and any discomfort or injuries you've experienced in the past. This helps them understand your needs, whether you're a recreational rider, a competitive cyclist, or a long-distance enthusiast.
• Current Bike Assessment: If you're using an existing bike, the fitter will inspect your current setup to identify any issues or areas that may need adjustment. They'll also ask you how the bike feels during rides (e.g., any pain points or discomfort).

Physical Assessment

• Body Measurements: The fitter will take detailed measurements of your body to establish your dimensions. This typically includes measurements like inseam length, arm length, torso length, and flexibility. They may also assess your range of motion and posture.
• Posture and Flexibility Evaluation: Your flexibility and overall body posture are key to determining your optimal riding position. The fitter might assess your flexibility (e.g., hamstring and hip flexibility) and other factors that could influence your riding comfort and performance.
• Injury History: A fitter will often ask about any existing injuries or chronic pain, especially in areas like the knees, back, or shoulders, to ensure they address any biomechanical issues that could worsen with riding.

Dynamic Rider Analysis

• On-Bike Positioning: After gathering measurements, you will be asked to ride your bike (or the bike you are being fitted to) on a trainer or rollers. The fitter will observe how your body moves and reacts in real time.
• Foot Positioning: The fitter will look at how your feet position on the pedals and assess your cleat setup (if you're using clipless pedals). Incorrect foot alignment can lead to knee pain or inefficient pedalling.
• Pedal Stroke Analysis: In a more advanced fit, the fitter may use video analysis or sensors to assess your pedal stroke. They'll observe how your knees, hips, and ankles move and look for any imbalances or inefficiencies that could be addressed.

High-Tech Tools & Measurements

• Laser Systems: Many precision fits utilise laser alignment systems to accurately measure angles and distances between key points on your body and the bike. These systems help to fine-tune your saddle height, handlebar reach, and other critical angles.
• Motion Capture or Video Analysis: Some bike fits use video cameras to record your movements from multiple angles. These recordings are then analysed frame by frame to fine-tune your positioning. The fitter might even use software to analyse your bike fit in real-time.
• Goniometers and Force Sensors: Some fits use goniometers (tools for measuring angles) and force sensors to quantify your body's angles and the forces being applied during pedalling. This allows the fitter to make precise adjustments to maximise efficiency and comfort.

Adjusting the Bike

• Saddle Height and Position: Based on your leg length and pedalling mechanics, the fitter will adjust your saddle height, fore-aft position, and tilt. Saddle height is one of the most critical adjustments to prevent knee pain and improve pedalling efficiency.
• Handlebar Height and Reach: The fitter will adjust your handlebar position (both height and reach) to ensure your back, neck, and wrists are in a comfortable, biomechanically efficient position. This might involve adjusting the stem length, the angle of the stem, or even swapping out handlebars.
• Crank Length: In some cases, the fitter may suggest changing the crank length based on your leg length and pedalling style, which can help improve power transfer and comfort.
• Cleat Positioning: If you use clipless pedals, the fitter will adjust the position of your cleats to ensure they are optimally placed for your pedalling mechanics. This can alleviate knee pain and improve overall pedal efficiency.

Test Rides & Fine-Tuning

On-the-Road Testing: After initial adjustments, the fitter will typically ask you to ride your bike on a trainer or outdoors to assess how the new setup feels. They may ask you to test various positions and report back on any discomfort, changes in your power output, or perceived improvements.

Continuous Adjustment: A precision fit often involves making incremental adjustments during the test ride, especially if any discomfort or issues are reported. This may include fine-tuning the saddle height, handlebar position, or pedal adjustments.

Biomechanical Analysis & Recommendations

• Posture and Efficiency Recommendations: Based on the fit and your body's mechanics, the fitter will offer suggestions on improving your posture or riding efficiency. This might include exercises for flexibility or strength, changes to your riding technique, or advice on how to improve your cycling form.
• Future Adjustments: If you're new to cycling or planning to increase your mileage or intensity, the fitter may recommend periodic follow-up adjustments. As your body adapts to cycling or as you change your fitness level, a fit might need slight tweaks over time.

Personalised Report & Follow-Up

• Written Report: After the session, some fitters will provide a detailed report with all the measurements, adjustments made, and any recommended changes. This can include before-and-after measurements and images, as well as advice on further improving comfort or performance.
• Follow-Up Support: A good precision fit often includes follow-up support, in case you experience any issues after the fit or need further adjustments.

Pearson Cycles collaborates with retail partners across the UK to provide access to professional bike fitting services. Their network ensures that riders can benefit from expert adjustments tailored to their needs, achieving the perfect balance between comfort and performance.

Bike Fits for Existing Bikes

Think a bike fit is only for new purchases? Think again. Many riders with existing bikes benefit greatly from professional adjustments. Over time, bodies and riding styles change, making periodic fits essential.

• Pain Alleviation: Resolve discomfort caused by poor alignment, such as saddle soreness, wrist pain, or lower back strain.
• Performance Boost: Optimised pedalling mechanics help you ride farther and faster without additional effort, improving your cycling performance.
• Extended Bike Life: A properly aligned bike reduces uneven wear and tear on components, extending the lifespan of your equipment.

Even if you've had a bike for years, a fresh fit can renew your love for cycling by addressing any discomfort or inefficiencies.

Alternatives to Professional Bike Fits

While professional bike fits are the gold standard, alternatives like bike sizing calculators and charts are often used as a starting point. These tools provide useful guidance but come with limitations. Here's a detailed comparison:

Bike Sizing Calculators - do they work?

Bike fit calculators are widely available online, offering a quick and easy way to estimate bike setup based on basic measurements like your height, inseam length, and sometimes your torso or arm length. While these calculators can give you a rough idea of what frame size or saddle height might work for you, they don't replace a professional bike fit.

What Bike Fit Calculators Can Do

• Convenient and Quick: These calculators are easily accessible online, allowing users to input basic measurements like height, inseam, and arm length to get immediate recommendations.
• General Frame Size Estimation: Provides a baseline size that can help beginners or those unfamiliar with bike geometry make an informed choice.
• Cost-Effective: Most calculators are free to use, making them an attractive option for those on a budget.

What Bike Fit Calculators Can't Do

• Lacks Personalisation: Calculators cannot consider unique physical factors such as flexibility, range of motion, or past injuries that might affect your ideal setup.
• Static Recommendations: They don't account for dynamic factors like posture, pedalling mechanics, or how your body moves on the bike.
• Accuracy Depends on Input: Mis-measurements or incorrect data entry can lead to poor recommendations, causing discomfort or inefficiency.

While bike fit calculators can be a helpful starting point, they're not a substitute for a comprehensive professional bike fit. If you want to maximise comfort, prevent injuries, and improve performance, a Personalised fit is the best option. Professional fitters take into account a variety of factors that calculators simply can't, offering adjustments that ensure your bike is perfectly tailored to your body.

Bike Sizing Charts

Bike sizing charts are commonly used by cyclists to help determine the right frame size when buying a new bike. These charts typically suggest a specific frame size based on key measurements like your height and inseam length. While bike sizing charts can provide a starting point for finding the right size, they are not always foolproof or the most accurate solution for every rider.

What Bike Sizing Charts Can Do

• Standardised Guidance: Often provided by bike manufacturers, these charts match frame sizes to common body measurements, ensuring compatibility with specific bike models.
• Quick and Easy Reference: Helpful for narrowing down options when shopping online or in-store without access to a fitter.
• Good for Beginners: Offers a simple way to identify appropriate sizes without needing in-depth cycling knowledge.

What Bike Sizing Charts Can't Do

• Overlooks Proportions: Charts focus on height and inseam but fail to address unique factors like arm length, torso length, or leg-to-torso ratio.
• Doesn't Address Riding Style: Whether you're aiming for an aggressive aerodynamic position or a relaxed touring posture, charts don't cater to these specific needs.
• No Adjustments for Comfort: Even the right frame size may require fine-tuning of components such as saddle height, handlebar reach, and crank length, which charts cannot provide.

Overall Considerations

While both tools offer valuable starting points, they lack the depth and accuracy of a professional bike fit. They are best used for:

• Preliminary research before purchasing a bike.
• Gaining confidence in size selection when professional fitting isn't immediately available.
• Assisting with budget-friendly decisions where in-person services may be unavailable.

However, these methods fall short for cyclists who prioritise comfort, efficiency, and injury prevention. For long-term benefits and a tailored fit, investing in a professional bike fit remains the superior choice as you get:

• Tailored Adjustments: Based on detailed measurements and real-time analysis, ensuring every aspect of your bike setup aligns with your body and goals.
• Problem Resolution: Professional fitters can address specific discomforts, inefficiencies, or injuries, providing solutions calculators cannot.
• Long-Term Value: A professional fit reduces the risk of injury, improves comfort, and enhances performance over years of cycling.
