The Mechanism Method

Bike fitting, without the guesswork.

Most fit methodologies apply rules. This one asks why. Three pillars, variables, mechanisms, forces, rebuilt from first principles, and used by the fitters I mentor around the world.

~3,000 Fits delivered across two decades of studio practice.
22 Years in cycling, from guide and mechanic to studio, lab, and boardroom.
2014 Founded the International Bike Fitting Institute (IBFI).
2020–23 Head of Biomechanics at Cyclologic Group.
The method

Three pillars. One method.

Miss any one and you're guessing. Get all three right and fitting becomes something you can defend to a peer, a researcher, or a court.

01 Variables

You can't fix what you can't see. Every symptom has a cast of contributors, thirteen, fourteen, sometimes more. Learn to list them, or keep rolling dice.

02 Mechanisms

If you can't explain why an intervention works, you're not fitting, you're guessing. The Mechanism Method gives every intervention a reason.

03 Forces

The physics most fits never touch. Every position is a balance of gravity, pedal reaction, and body mass. Once you see it, you can't unsee it.

Why listen

Twenty-two years. Still asking why.

  • Founder of the International Bike Fitting Institute (IBFI).
  • Head of Biomechanics at Cyclologic & Velogic, fitting some of the most demanding cyclists on earth.
  • Steve Hogg certified (2022), one of fewer than twenty fitters worldwide to complete his four-week residential programme.
  • Worked with GB Paratriathlon, including Rio Paralympic medallists, and the UK's top triathletes throughout the 2010s.
  • Post-graduate research on ankle biomechanics in time-trial cyclists.
For fitters

Three ways to work with me, in order.

The ladder. Low commitment to high, priced and specific. Self-select into the rung that fits where you are today.

Case Consultation

€220 / hour

One hour. One rider you cannot solve.

You send the case ahead of time. We spend an hour inside the mechanism. You leave with a plan you can apply at your next appointment.

Mentoring

€400 / month

For fitters rebuilding how they think.

One 1:1 hour per month, WhatsApp access between calls, and a weekly Thought Trigger sent only to mentees. Rolling, cancel any time.

Practice Review

€2,000

Three months. Weekly. Invitation only.

Your entire practice, systems, pricing, process, outcomes, held up to the light over twelve weeks of weekly calls, plus WhatsApp and email between them. Eight slots per year.

Thinking

The thinking, in public.

New essays, case breakdowns, and videos from the studio. The work the method is made of.

The shortest version of the method, a single essay that sets out variables, mechanisms, and forces, and what changes when fitters work through all three.
