Knowing where you stand should not be a luxury
A performance diagnostic in Switzerland starts around Fr. 150.–. So most riders do one, once. Plenty do none at all. That is a strange way to price something that only pays off when you repeat it.
The problem with testing once
A lab test gives you a very good number on one particular Tuesday. It tells you where you were. Finding out whether anything has changed since costs the same again. So most people skip the second one. The number gets quoted for a season and never steers a decision, because the useful part was never the number by itself, it was the gap to the last one. And the riders who would gain most have no team, no coach and no budget line for sports science: they train hard and guess, because guessing is free and measuring is not.
So we priced it so that testing again in eight weeks is something you just do. Not to look cheap, but so the second measurement actually happens.
A number without its origin is a horoscope. Every value in the report is labelled with how it got there: read, modelled, or assumed. Where we cannot show the derivation, we do not show the number. And one direction beats twelve metrics: every report ends with a training focus, not with a menu of options that only hands the work back to you.

What we will not do
We will not sell or trade your ride data. It is not a side revenue stream we are keeping quiet about, and there is no version of this business where it becomes one.
We will not turn this into a subscription that deletes your history when you stop paying. You bought a report; the report is yours.
We will not present an estimate as a measurement. Where a number is modelled, the report says modelled, even where saying so makes the product sound less impressive than a competitor's.
We will not tell you something is wrong with you in order to sell you the fix. The report names a training focus. It does not diagnose you.
Who is behind it
A small Swiss team. The analysis engine, the physiological models and the site are built by the people whose names are on the team page. Nothing is outsourced, and there are not many of us.
The honest version is on the science page
Principles are cheap. The place to check whether we mean them is the section where we set out where our own models stop working.
