Pressure mapping is a revolutionary tool that's transforming the way we approach bike fitting. Unlike traditional methods that often rely solely on subjective feedback, pressure mapping provides objective data on how your body interacts with your bike. This technology allows us to uncover hidden imbalances and inefficiencies that might be limiting your performance and comfort.
Often, cyclists unknowingly compromise their potential due to factors like leg length discrepancies, foot instability, pelvic misalignment, or improper crank length. These issues can lead to discomfort, reduced power output, and even long-term injuries. Surprisingly, pain is often a late indicator of these underlying issues. Pressure mapping enables us to identify these problems proactively before they escalate into more serious concerns.
In the following sections, we'll delve deeper into how pressure mapping works, its benefits, and real-world examples of its application.
What is Pressure Mapping in Cycling?
Pressure mapping is a high-tech sensor mat that acts like a silent observer beneath your saddle. This thin and flexible pad is embedded with 64 pressure sensors that capture a detailed map of how your weight is distributed across the saddle. The data is then wirelessly transmitted to a computer, allowing for live indoor and outdoor measurements during a bike fitting session.
How Pressure Mapping Works
Pad Setup: The thin, pressure mapping pad is placed on your saddle.
Rider Engaged: You hop on your bike and maintain your natural riding position. There's no need to alter your style for the measurement.
Pressure Data Captured:
Statically: This provides a baseline reading of pressure distribution while you're seated.
Dynamically: Provides live measurements while you're pedaling, offering valuable insights into pressure changes during real-world cycling.
Pressure Readings are Displayed on a Color Scale: This creates a visual map where different colors represent varying pressure levels across the saddle surface. In our example, blue is almost no pressure whereas red is significant pressure.
Data Analysis: By analyzing this data, bike fitters can identify areas of high pressure, imbalances, and potential discomfort zones. This information is crucial for making informed adjustments to the bike setup, such as saddle position, height, tilt, and even handlebar adjustments.
Validation: In the data analysis process, pressure mapping is then used to validate that the adjustments selected impacted the rider. Before and after pressure mapping images tell the story of the positive impacts and are consistent indicators of bike fitting progress.

Understanding Pressure Mapping Data
Beyond the visual representation, pressure mapping systems offer a wealth of quantitative data that inform the bike fitting process. This data includes:
Mean pressure across the saddle: Provides an overall picture of pressure distribution.
Front and rear saddle pressure: Compares pressure on the pubic bone and sit bone areas.
Max pressure values and their location: Identifies peak pressure points on the saddle.
Left and right side pressure comparison: Reveals imbalances in weight distribution.
Center of movement and pelvic tracking pattern: Shows how the pelvis moves during pedaling.
Gross angle of pelvic hemisphere alignment: Measures pelvic rotation and tilt.
This comprehensive data allows bike fitters to make informed adjustments to the bike setup, optimizing comfort, efficiency, and power transfer.
The Benefits of Saddle Pressure Mapping
Saddle pressure mapping provides invaluable insights that go beyond simply identifying discomfort. By quantifying pressure distribution, we can unlock a range of benefits for cyclists of all levels.
Identify Hidden Pressure Points: Sometimes, discomfort arises from subtle pressure imbalances that traditional bike fitting methods might miss. Pressure mapping reveals these hidden pressure points, allowing for more targeted adjustments during your bike fit.
Optimize Saddle Comfort: For many cyclists, saddle discomfort is a persistent issue. Pressure mapping helps identify the ideal saddle position and type for your unique anatomy, leading to a more comfortable ride.
Improved Power Transfer: Uneven pressure distribution can hinder your power transfer and efficiency. Pressure mapping helps with the identification of hindrances and with the help of an expert fitter, adjustments made can make significant improvements.
Prevent Injuries: Persistent pressure points can lead to injuries over time. Pressure mapping used during a bike fit helps identify potential problem areas before they develop into aches and pains.
Inform Saddle Selection: Increase understanding of your specific pressure distribution which aids in the proper saddle selection for optimal comfort and performance.
Improve Bike Fit Accuracy: Provide data-driven insights for precise adjustments to bike components and data validation that these changes positively impacted the cyclist.
Informed Decision-Making: The data can reveal imbalances that require multiple bike fitting adjustments. For instance, improper arch support, crank length or foot correction issues can lead to pressure points on the saddle. A skilled bike fitter will use the pressure mapping data in conjunction with other assessments to make informed adjustments throughout your bike setup, creating a holistic solution for optimal comfort and performance.
The power of pressure mapping lies in its ability to provide a wealth of data beyond a simple static measurement. By capturing dynamic pressure changes while you're cycling, bike fitters gain a deeper understanding of your body mechanics and how they interact with the bike.
A Real-World Example of Pressure Mapping in Action
To illustrate the power of pressure mapping, let's examine a real-world case study:
One of our clients came in for a Performance Bike Fit, seeking ways to improve their efficiency and overall riding experience. Although they reported no immediate saddle discomfort, our pre-fit evaluation and pressure mapping analysis revealed interesting insights.
The pre bike fit evaluation showed greater arch elongation and a slight navicular drop. Additionally, we observed a tightness in the left hip and a mild functional leg length discrepancy. The pressure mapping verified our observations.
To address these imbalances, our fitter implemented the following adjustments:
Crank Length Modification: Adjusted crank length to improve range of motion and pedaling efficiency.
Custom Insoles: Prescribed custom insoles to stabilize the flexing foot and support the arch.
Saddle Adjustment: Changed the saddle to a wider model with a narrower nose to improve weight distribution.
These modifications resulted in a more balanced weight distribution (left and right), increased stability, and improved overall comfort and power output for the rider.
This case highlights the importance of a proactive approach to bike fitting. Pressure mapping is a valuable tool that, when combined with a skilled fitter, can uncover hidden issues and create a truly personalized bike fit experience. By identifying and addressing underlying problems, we can help cyclists achieve optimal comfort, efficiency, and performance.
Pressure mapping goes beyond identifying saddle issues. It provides a comprehensive picture of how a cyclist interacts with their bike, allowing for targeted adjustments that enhance the overall riding experience.
