Expand your cadence range.
Build dynamic range and keep it under load. Six short seated sprints map your torque–cadence profile and reveal exactly where your power lives.
What this does
Test with six short, seated sprints (6–8 s) in different gears. The calculator plots your torque–cadence range and shows:
- • Peak rpm: your optimal coordination point
- • Coordination band (±10%): your usable range
- • Training bands: Force on the left, Frequency on the right
- • Fatigue overlay: optional fresh vs fatigued shift
Why it matters
There is no perfect cadence. Performance improves when you produce high power across a wider band of rpm and hold that band late in rides and races. This profile shows where your range is now, and where to train it.
The test
How it works
Step 1: Fresh. Do 6 × seated sprints, 6–8 s, no shifting. Log your rpm and peak watts for each, then plot.
Step 2: Fatigue (optional). After a long ride, repeat the same six sprints and plot again to see the fatigue shift in your profile.
