About
The long way to a simple method.
Nearly two decades in cycling: from guide and mechanic to studio fitter, from practice to the biomechanics lab and back, from founder of an independent professional body to head of biomechanics at Cyclologic Group, now running my own studio, my own software, and my own consultancy.
01 · Origins
I was a fitter before I was a biomechanist.
I studied Economics, then International Political Economy, before I'd thought seriously about anyone's saddle height. The path into cycling was work, not school: first as a Development Officer at British Cycling, then as a guide and bike mechanic based between Manchester and Andalucía. I opened my first fit studio in 2010, became one of six Master Retül Fitters in the UK, and spent the next decade fitting riders of every level.
The science came later, on purpose. After three years of running a busy studio, I went back to do an MRes at Nottingham Trent, because the rules I'd been trained in weren't holding up with the riders in front of me, and I needed to understand why. The PhD followed in 2015. It's in cycling biomechanics, and it is currently paused: the research is done, the thesis is half-written, but the last few years have given other work priority.
I describe what I do now as applied cycling biomechanics, and the word doing the work is applied. I sit on the fence between scientist and practitioner, permanently. Practice came first; research came after the questions practice couldn't answer. Scientific principles inform the method; the results in the studio keep it honest.
02 · The studio years
Then I got put on the hard cases.
Through the studio years I've run something close to three thousand fits, overwhelmingly everyday cyclists with pain, questions, or performance goals, and, alongside them, a smaller number of ProTour riders, elite triathletes, and GB Paratriathletes preparing for Rio and Tokyo medal campaigns. The mix mattered. The everyday fits taught me the volume and the patterns; the hard cases taught me the method.
When a rider's training is already at its ceiling, the fit becomes the variable that moves the needle; you don't get to guess. You don't get to hide behind "it feels right". Every adjustment is a hypothesis, and performance publishes the results.
Paratriathlon was the real teacher. When a rider's anatomy doesn't follow the textbook, when you're working with prosthetics, limb difference, asymmetry, or classification-specific constraints, your rule-based templates don't just underperform. They actively harm. You either learn to fit from mechanisms, or you quietly stop being useful.
That's where the method started to clarify. Not in a single moment of insight, but in the accumulating pressure of cases where the rules didn't fit the rider.
03 · IBFI
Then I tried to fix the credential problem.
In 2014 I founded the International Bike Fitting Institute. The industry had a transparency problem: every other fitter was calling themselves a "Master" of something, brand-specific courses were being treated as independent standards, and the certifications on the market told a rider nothing about whether the person behind them could actually think through a fit.
IBFI wasn't a teaching institution, and it wasn't selling a curriculum. It was the independent professional body that cyclists and fitters could point to when they wanted to know what a credential actually meant.
A decade on, it's still operating, still independent, and still doing what it was built to do. I stepped back from its day-to-day in 2023, when two other commitments earned priority.
04 · Cyclologic Group
The Institutional Years.
From 2020 to 2023 I was Head of Biomechanics at Cyclologic Group, overseeing biomechanics, education, and technology integration across Cyclologic Education, Velogic, and Bike Fitter Supply. This was the chapter where the international work actually happened. I built the group's international education network, which went on to become the training partner for both Velogic and Trek Bikes, designed and validated new motion-capture and analysis features, assisted on wind-tunnel positional testing for USA Triathlon, and led cross-disciplinary problem-solving across biomechanics, engineering, and the commercial partner network.
I learned the things there that you can only learn inside an institution: how to write a curriculum someone else can deliver without losing the logic, how to validate a measurement protocol against the messy realities of different studios, and how to keep a methodology consistent across fitters who have never met each other.
05 · Steve Hogg certified
Fewer than twenty, worldwide.
In September 2022, I completed Steve Hogg's four-week residential certification, one of fewer than twenty fitters in the world to have done so. Most fit accreditations are a one- to three-day course. Steve's is a month. You live with him. He vets every applicant before agreeing to train them, so you have to already be an experienced fitter who meets his criteria before you're in the room.
It's the most exacting programme in the discipline, and the kind of course you only sit when you think you already know what you're doing, which is precisely when you find out how much you don't.
06 · The pivot
And then, in 2023, I stepped out.
In 2023 I left the Cyclologic role to build AIDOS, open a studio under my own name, and consult directly with the brands and teams I most wanted to work with. It was the right move two years earlier than it felt like it was.
AIDOS. A positional tracking and comparative-fit system that builds a long-term, portable record of a rider's position: what was set, what changed, when, and why. It gives everyday cyclists the kind of continuity most of them have never had: a complete history of their fit across time, across bikes, and across fitters, with the reasoning alongside. The method has always needed a tool that could scaffold a fitter's thinking while they were using it. I stopped waiting for someone else to build it.
Consulting. Brand and performance consulting under my own name, on geometry, sizing, and the commercial translation of biomechanics into product. A practitioner-scientist has a narrow but valuable role inside a performance brand, bridging what the engineers can measure and what the riders can actually feel.
The site. And this: the public home the method has needed for a decade. Essays, cases, a studio that still sees riders, and a ladder for fitters who want to work with me. For three years I've had the method and the tool. Now the thinking needs to be loud about itself again.
07 · Now
This site is what comes next.
Three things live here: the Mechanism Method, a personal fitting practice, and a ladder for fitters who want to work with me. The method underpins the practice. The practice feeds the method. The fitter ladder exists because the only way the industry gets better is if the fitters who already care get sharper.
I'm not building an empire. I'm making the way I think transferable, through the Case File, through one-to-one work, through the essays, through AIDOS, through the consultancy, and through whatever else turns out to be useful.
If any of that matches where you are, you'll find something here. If it doesn't, that's fine too. The method isn't for everyone, and the site doesn't try to be.
Off the clock.
Based in Spain. Most of the thinking happens on the bike.
