About
SpeedLab BikeFit Studio is London's premier destination for performance cycling assessment and coaching. Located in Clapham, SW London, the studio specialises in bespoke fitness preparation for cycling, triathlon, and Ironman events, catering to athletes of all abilities — from enthusiasts finding their first bike to seasoned competitors chasing podium positions. At the core of their offering is the Retül 3D motion capture bike fitting system, which streams rider movement data in real time, enabling precise adjustments across all contact points — saddle, handlebars, cleats, and more. Each fit is accompanied by a detailed report covering body angles and bike setup, plus post-fit support and product recommendations. Beyond bike fitting, SpeedLab provides a wide range of coaching services: fully loaded online power studio classes run via Zwift and Discord, 1-2-1 personal training packages, and bespoke training plans tailored to individual goals and racing calendars. Their Fit Lab offers metabolic testing and training zone analysis to ensure athletes are training at the right intensity. Additional services include new bike sizing and BikeFinder consultations to help riders choose the correct frame and components before purchasing, plus training camps in Mallorca and Wales. SpeedLab is ideal for cyclists, triathletes, and multi-sport athletes who want data-driven insights to ride faster, more comfortably, and injury-free.

Frequently Asked Questions
What is a Retül 3D bike fit and how does it differ from a standard fit?
Retül uses infrared 3D motion capture sensors placed on the rider's body to stream biomechanical data in real time while they pedal. This provides precise, dynamic measurements of joint angles and movement patterns rather than static assessments, resulting in a more accurate and evidence-based fit.

SpeedLab offers a full range of fits including Road & Gravel, TT & Triathlon, Urban & MTB, Physio Cycling Fits, Saddle Testing, Shoe & Cleat fitting, and new BikeFinder sizing sessions for pre-purchase guidance.
