Discover the core approach behind Andy's work.
Applied cycling biomechanics, grounded in practice.
Andy Brooke is a bike fitter, educator and consultant based in Valencia, Spain, working with cyclists, bike fitters and cycling brands worldwide.
At a glance
Andy has delivered more than 3,000 bike fits over two decades in cycling, from everyday riders through to elite and professional athletes, including GB Paratriathlon medallists and world-record endurance riders. He is the founder of the International Bike Fitting Institute (IBFI), a Steve Hogg-certified fitter, and has held senior biomechanics roles within the Cyclologic Group.
Andy's work focuses on applied cycling biomechanics, understanding how position, movement and forces interact, and using that knowledge to improve outcomes for both riders and fitters.
From practice to research and back again
Andy's route into bike fitting began in practice rather than academia.
He worked in cycling as a guide and mechanic, and later as a Development Officer at British Cycling, before opening his first bike fitting studio in 2010. Over the following decade he built a high-volume studio practice, working with riders of all levels and developing a deep understanding of common problems and recurring patterns.
That experience led him back into formal study. After several years of full-time fitting, he completed an MRes in cycling biomechanics at Nottingham Trent University and began PhD research in the same field, focusing on ankle biomechanics in time-trial cyclists.
This combination of hands-on experience and formal research underpins his current approach: practical work drives the questions, and scientific principles help explain and refine the answers.
Working at the highest level
Alongside everyday riders, Andy has worked with elite and professional athletes across multiple disciplines.
This includes GB Paratriathlon medal campaigns, work with short-track speed skater Elise Christie during her crossover into cycling, and positional work on Leigh Timmis's Guinness world-record ride across Europe.
Much of his work at this level sits within team environments and confidential projects, but the principle remains the same: when performance is already close to its limit, small changes in position can have measurable effects, and decisions need to be based on clear reasoning rather than assumption.
Building standards in bike fitting
In 2014, Andy founded the International Bike Fitting Institute (IBFI) to address a lack of clarity and consistency in bike fitting qualifications globally.
The IBFI was created as an independent professional body, not a training provider, with the aim of helping cyclists and fitters understand what different certifications actually represent.
He stepped back from day-to-day involvement in 2023, but the organisation continues to operate internationally.
Cyclologic and international work
From 2020 to 2023, Andy was Head of Biomechanics at Cyclologic Group, overseeing biomechanics, education and technology integration across Cyclologic Education, Velogic and Bike Fitter Supply.
During this time, he:
- helped build an international education network
- contributed to motion capture and analysis systems
- worked on wind tunnel positional testing projects
- supported collaboration between biomechanics, engineering and commercial teams
The role provided experience in scaling methodologies across multiple fitters and locations, and translating biomechanics into tools, education and product development.
Steve Hogg certification
In 2022, Andy completed Steve Hogg's four-week residential certification, one of fewer than 20 bike fitters worldwide to have done so.
The programme is known for its depth and selectivity, with applicants required to demonstrate significant prior experience before being accepted.
Independent practice, consultancy and AIDOS
In 2023, Andy moved back into independent work, focusing on three areas:
Bike fitting in Valencia
A one-to-one studio practice working with cyclists across a wide range of needs, from comfort and injury management through to performance.
Fitter development
Mentoring, case consultation and practice review for bike fitters looking to improve how they approach complex cases.
Consulting and product development
Working with cycling brands and organisations on geometry, sizing, and the application of biomechanics in product and performance contexts.
Alongside this, he developed AIDOS, a positional tracking and comparative-fit system designed to create a long-term record of a rider's position and the reasoning behind changes over time.
Approach
Andy describes his work as applied cycling biomechanics. In practice, that means focusing on:
- what is happening in the rider
- why it is happening
- how position influences forces and outcomes
The aim is to move beyond rule-based fitting and towards decisions that are structured, repeatable and explainable.
Based in Valencia, working globally
