Dynamic biomechanical assessment of a cyclist at the ONE laboratory

Summary

ONE 3D Performance Lab

In the laboratory · by appointment

Four instruments answering four different questions: a bike that changes geometry without you getting off it, a dynamometer that measures each leg separately, cameras tracking your knee in three dimensions, and calipers under an international protocol.

Where it is
Kr 13 #118A-48, Usaquén, Bogotá, by appointment. Whatever does not require the lab is done remotely.
What gets measured here

Geometry and position: GURU Ultimate 3D moves saddle, bars and cranks while you pedal under load.

Force per side in newtons and joint range of motion in degrees, with VALD DynaMo Plus dynamometry.

Movement and proportions: 3D motion capture and ISAK Level 2 anthropometry.

What it costs to use it
from COP 595,000approx. USD 190

What it does not do

No instrument answers another one, and none decides on its own: the lab measures, and a named person interprets. It is also not booked separately: it is used inside BIKEFIT and BIKEFINDER.

TECHNOLOGY

Cycling technology: the ONE 3D Performance Lab

Machines that answer specific questions.

A motorised bike that changes geometry without you getting off. An anchored dynamometer that measures each leg separately, in newtons. Cameras that track your knee in three dimensions. A skinfold calliper that measures skinfold thickness under a repeatable international protocol. Four instruments, four different questions, and none of them answers another's.

Two decades of applied cycling science.

Cycling movement and position analysis on a data interface

Applied technology

Capturing more data only matters when it improves the intervention.

An instrument that measures very well something that is not limiting you is worth nothing. Every instrument below earned its place by answering a question that kept coming up in sessions.

Current stack

What is in the lab today, and what each thing is for.

None of these machines makes anyone faster on its own. What they do is turn an impression into a number you can measure again in three months, which is the only way to know whether a change worked.

A. Develop performance

ONE training system

Sessions arrive through TrainingPeaks; your rides are imported, analysed and published to your Athlete Portal to decide which session belongs in this week and which one should move.

If you ride worse one week, it shows how much load you did against your usual. Whether it was sleep or work is something you tell your coach, who crosses it with the data.

B. Optimize position

GURU Ultimate 3D

A motorised bike that moves saddle, bars and cranks millimetre by millimetre without the rider getting off.

Comparing two positions stops depending on memory: the previous one is still in your legs when the next arrives.

C. Assess capacity

Dynamometry + anthropometry

How much force each leg produces, how much range each hip has, and how far apart the two sides are, measured against a fixed anchor so the test can be repeated.

Tells you which posture your body can hold for three hours, not which one it survives for three minutes.

D. Monitor and project

Applied data science

Geometry, pedaling sensors, power and data analysis, with the Athlete Portal and the coach’s team board in operation.

Turns complex information into reports you can review, scenarios and verifiable actions.

Method and architecture

Before the bike moves, the rider is assessed.

The dynamometer, the calliper and motion capture are not here to lengthen a list of devices. They answer a question that comes before any adjustment: which posture this body can hold for three hours, with the mobility, the strength and the side-to-side differences it has today.

Frequently asked questions

Questions about the laboratory.

What does the GURU Ultimate 3D do that a traditional fit cannot?

Change the geometry of the position while the rider keeps pedalling. In a traditional fit the session has to stop so a component can be moved or replaced; on the simulator the change happens on the move and under load, so every adjustment is judged with the body producing power rather than standing still.

What is the ONE Alpha Data Stack?

The data layer of the system: training, load, monitoring and reporting. Alpha develops and controls performance across the process; GURU observes and modifies position in real time. Two halves of the same laboratory — one over the data, one over the body.

Does the technology decide, or does the professional?

The professional decides. The systems measure, order and present; artificial intelligence is used to organise information and stays subordinate to interpretation. What a data point means and what to do about it is professional judgement, which is why it is explained case by case instead of handing over a number without a reading.

Is everything listed here in operation today?

No, and which is which is stated. The GURU simulator, dynamometry, 3D capture and anthropometry are operational and used in every session. So are the Athlete Portal, with private reports and ONE Readiness, and the team board for the coach. The portal simulator and the Bayesian power–duration engine are still experimental, and the other lines under construction are on the research and development page. Presenting a line of exploration as though it already measured something would be exactly what this laboratory avoids.

Does capturing more data improve the result by itself?

No. More signals without interpretation produce noise, not judgement. A measurement is only worth taking if it changes the intervention: if measuring it does not alter what happens next, it is surplus. That is why an assessment starts from the question in the case, not from the equipment catalogue.

Credentials · Scientific direction

Who interprets what the machines measure.

As Scientific Director and Head Coach across multiple teams, he integrates real-time GURU biomechanics, dynamometry for strength and range of motion, MOCAP 3D, ISAK Level 2 anthropometry, sports nutrition (ISSN), power, data science and biostatistics to improve measurement precision, support professional decisions and validate the athlete’s response.

Measuring precisely is not promising certainty. It is being able to repeat the measurement and compare.

Athletes supported by ONE have earned regional, national and Pan American medals and competed at World Championships.
More than 3,000 bike fit and biomechanical assessment processes carried out over the years, with different instruments and stages of the laboratory: not all of them used GURU, 3D capture or the current equipment.
Force is measured with the dynamometer anchored to a fixed point, because a hand-held test stops being comparable between sessions.
Twenty years coaching cyclists, from five-hour-a-week amateurs to riders at world championships.
