Testing & tech services.
Turn data into speed.

One page. Six tools. Same goal: remove guesswork. Dial in hydration with AHi sweat testing, set accurate zones with a MAX test, manage heat with CORE body temperature insights, optimise kit fit with a NØPINZ 3D scan, spot health/nutrition gaps via (Forth)Edge blood testing, and refine pedalling with Rotor OCP metrics.

The tech menu

Pick the bottleneck you want to solve first — then we can layer the rest as needed.

Hydration • FLOWBIO AHi

AHi sweat & sodium testing

Measure fluid + sodium losses, then turn it into training/race plan.
2h session £125 Bike + power (or discuss options)
  • FLOWBIO AHi sensor used during a ride at race power.
  • Outputs precise hydration + sodium targets to maximise training and racing.
  • Personalised report emailed after the session, plus Q&A.
AHi testing uses the FLOWBIO AHi arm sensor.
Fitness • Zones

MAX power / heart-rate testing

Stop guessing your zones. Set them from your own personal data.
1.5h session £60 Bike + HR strap + power meter
  • Proven protocol to find exact Peak Power Output (PPO).
  • Accurate HRmax + power markers to anchor Z1/Z2/Z3 and race pacing.
  • Zones report and follow-up Q&A.
MAX TEST uses a proven RAMP protocol.
Heat • CORE

CORE body temperature testing

Use real-time thermal data to guide heat training for race day performance gains.
2h session £125 Optional sweat test - ask at time of booking.
  • CORE sensor data used to monitor core body temperature and heat strain in real time.
  • Guidance on pacing/cooling decisions and how to structure heat sessions safely.
  • Works brilliantly paired with AHi sweat testing for a full hot-race fueling plan.
Testing uses CORE sensor for skin and core temperature analysis.
Kit • Fit

NØPINZ 3D scan (made-to-measure kit)

Improve comfort and aerodynamics by getting the suit fit nailed.
Optional extra at NOPINZ, North Devon. Quote on request Best paired with BioRacer EROfit or other test sessions.
  • 3D scan option referenced as an add-on within the BioRacer AEROfit service.
  • Use the scan to support made-to-measure suit choices and better on-bike fit.
  • Combine with testing for “data + kit” decisions in one visit.
NØPINZ 3D scan only available at NOPINZ HQ.
Health • Blood

(Forth)Edge blood testing

Spot weak links (iron, B12, vitamin D, hormones, etc.) before they become performance limits.
Home testing From ~£90+ Optional coaching add-on
  • Build a bespoke blood test (Edge) and use results to guide nutrition and recovery.
  • Ideal for fatigue, recurrent illness, low energy, or “training isn’t working”.
  • We’ll translate results into practical changes (food, supplements, training load).
(Forth)Edge tests are undertaken remotely.
Pedalling • Rotor

Rotor COP / pedalling metrics check

Use Rotor power metrics to refine how you deliver force through the pedal stroke.
Session by arrangement Quote on request Rotor products can be collected at the same time
  • Analyse Rotor pedalling metrics (e.g., crank-based power + Rotor-specific metrics) to spot inefficiencies.
  • Option to explore chainring orientation/optimisation (OCP-style tuning) where relevant.
  • Practical action list: cadence targets, position tweaks, equipment choices, and drills.
Rotor UK (Velotech Services) can advise on cranks, chainrings and bottom brackets.

FAQs

A few common questions that save back-and-forth.

Do I need a power meter for AHi sweat testing?

Ideally yes. The FLOWBIO AHi test notes that the session uses a trainer plus a power-measuring system (your bike power meter or an agreed setup). If you don’t have power, mention it when you enquire and we’ll work out options.

Where do the sessions happen?

Most 1-2-1 services are delivered in North Devon. Some sessions (like BioRacer) can be run as pop-ups for groups by arrangement.

Can I bundle tests into one day?

Yes — that’s exactly what Pro Days and the Aero Day add-ons are for (AHi + CORE temperature measurement are both listed as optional extras).

Is Edge blood testing something you do in-person?

Edge tests are typically home sampling. The value is in choosing the right panel and then translating results into practical actions for training, diet, and recovery.
