Why does cycling hurt? The Ride Pain Decoder
Most cycling pain traces back to a bike setup that doesn't match your body, and a few small changes often help. The Ride Pain Decoder is a 22-page field guide from Number5 that helps you find the likely cause and fix it one change at a time.

What is The Ride Pain Decoder?
The Ride Pain Decoder is a 22-page digital field guide from Number5 for troubleshooting pain on the bike: sore sit bones, numb hands, hot feet, achy knees, and a stiff neck. You pick the body area that hurts, answer a few questions, and follow a short path of setup changes. Free adjustments come first and purchases come last.
It is built for gravel, mountain and road riders, and it uses specific numbers (such as 5 mm and 1–2° adjustments) so you are not guessing how far to move something. It costs $19 and arrives as an instant .zip download. It is general education about bike setup, not medical advice.
Where does it hurt?
Where the pain shows up points to the likely setup suspects. The rules of thumb below are starting points, not diagnoses. The guide walks you through each area in order.
Why does my saddle hurt?
Saddle pain usually comes down to saddle height, tilt, fore-aft position, or a saddle shape that doesn't suit your sit bones. Change one of these at a time and ride before changing another.
Why do my hands and wrists go numb?
Numb or sore hands usually point to too much weight on the bars, which can come from a saddle tilted nose-down, a long reach, bar angle, or high tire pressure. Check how your saddle sits before you touch the bars. Read Why Your Hands Go Numb on the Bike (and 5 Fixes to Try).
Why do my feet burn or go numb?
Hot or numb feet most often come from shoe fit, overtightened closures, cleat position, or a lack of support under the arch. Loosen the shoe before you change anything else.
Why do my knees hurt when I ride?
Where the knee hurts is a clue: front, back and side pain tend to have different setup suspects, usually saddle height, saddle fore-aft position, or cleat position. Small changes are better than big ones.
Why do my neck, shoulders and lower back ache?
Neck, shoulder and lower-back aches often point to a reach that is too long, bars that are too low for your current flexibility, or a jump in ride volume. A shorter reach or slightly higher bars is a common first test.
How does The Ride Pain Decoder work?
The Ride Pain Decoder works by sending you through a short, ordered path for the one area that hurts, so you change one thing at a time. The steps are:
- Do the 10-second sanity check first.
- Pick the decoder for the body area that hurts.
- Answer a few questions to find your path.
- Follow the path, starting with free adjustments.
- Change one thing at a time and ride two or three times before judging it.
- Record each change in the Change Log spreadsheet.
- If a red flag appears, stop and see a clinician. If you are still stuck, book a bike fitter.

When should I see a clinician or a bike fitter?
See a qualified clinician if your pain is severe, lasts a long time, or comes with numbness, swelling or weakness. Stop riding until you have been checked. The Ride Pain Decoder is general education about bike setup, not medical advice, and it is not a substitute for a clinician.
Book a bike fitter if you have tried the free adjustments, changed one thing at a time, and the pain is still there, or if you are not confident making an adjustment yourself. The guide explains what to bring to a fit. If you are not sure about a fastener, use a qualified mechanic.
Frequently asked questions
Is The Ride Pain Decoder medical advice?
No. The Ride Pain Decoder is general educational information about bike setup and comfort, not medical advice, diagnosis or treatment. Results aren't guaranteed. If pain is severe, lasts a long time, or comes with numbness, swelling or weakness, see a qualified clinician.
Do I need special tools?
Most riders will need basic bike tools, such as a set of hex keys. Tighten fasteners to the manufacturer's torque specifications. If you are not confident making an adjustment, use a qualified mechanic or bike fitter.
What format is it, and how do I get it?
It is one .zip file containing the 22-page PDF guide and a Change Log spreadsheet (XLSX). The download link appears after checkout and is also emailed to you. It opens on a computer, or you can unzip it on a phone by tapping the file.
Can I get a refund?
No. All digital sales are final because the guide is delivered instantly. The exceptions are a broken or expired download link, a damaged file, or a duplicate charge: email contact@number5.cc within 30 days of purchase. If you're unsure, download the free sample first.
Is it for road, gravel and mountain bikes?
Yes. Number5 makes it for gravel, mountain and road riders.
How long does it take?
The sanity check takes about 10 seconds, and the download is instant. Each change is then tested over two or three rides, so working through a problem takes a few rides, not a few minutes.
