Specialized Body Geometry- BG Fit System
Ride faster, longer and in greater comfort, while reducing the chance for injury.
The Specialized Body Geometry DATA Capture is a comprehensive fit philosophy created to help cyclists ride faster, longer and in greater comfort, while reducing the chance for injury.
Developed after years of working with Dr. Andy Pruitt Ed.D., PA of the Boulder Centre for Sports Medicine and found at both of our shops.
Watch the introduction video on the BG Fit system:
We have a dedicated Body Geometry DATA fit room and a second room at our Specialized Kingston store (just minutes away) that is also equipped with the state of the art Body Geometry DATA system too.
Body Geometry DATA gives you the rare opportunity to see yourself riding a bike while the technician takes measurements. With a video monitor displaying every adjustment, you can actively see the changes being made to improve your posture, performance and comfort. After you've completed your Body Geometry fitting, you will receive a detailed report with your personal measurements, photos and videos so you can compare and quantify your results from start to finish.
With our fully trained Body Geometry technicians we aim to give you the best possible fit on your bicycle possible. For the Body Geometry DATA bike fitting we charge £200 and the fit takes approximately 2 1/2 hours.
If you'd like to know more details or book a fitting session then contact Sigma Sport at 020 8614 9777 or via Email. Our second bike fitting room is at our Specialized store located a short distance away in Kingston. You can call them on 020 8549 5888 or by Email.
