**Quick answer:** The frame number on a Commencal is usually underneath the bottom bracket, or on the underside of the down tube where the suspension linkage crowds the shell. Because Commencal sells direct, the original order confirmation matters as much as the number itself.

On a Commencal, check underneath the bottom bracket first, then the underside of the down tube and the head tube. Commencal builds aluminium full-suspension mountain bikes and sells them direct, so keep the original order confirmation as well as the frame number: with no dealer in the chain, that email is often the only proof of purchase there is.

## Start under the bottom bracket.

This is the most common place to find a Commencal frame number. It is the part of the frame between the pedals, on the underside.

1. Put the bike somewhere safe and well lit.
2. Turn it upside down carefully, or place it in a workstand.
3. Look underneath the frame where the cranks meet the bike.
4. Wipe away mud, grease or road dirt.
5. Use a phone torch if the number is hard to read.
6. Take a clear photo before typing the number into a checker.

### If it is not under the bottom bracket

- Near the rear dropouts, where the back wheel fits into the frame.
- Around the seat tube.
- On the underside of the down tube.
- Near the head tube at the front of the bike.
- On the original sales receipt.
- In your Commencal registration email or paperwork.
- With the Commencal dealer that sold the bike.

## What a Commencal frame number looks like

A unique alphanumeric code stamped or etched into the aluminium frame. Commencal does not publish a public serial format, so use the full code.

### Not the frame number

- Commencal Meta
- Commencal Supreme
- Commencal Clash
- Commencal Absolut
- Commencal Tempo
- Frame size
- Shock serial number
- Fork serial number
- Pivot bearing codes

## Direct-sold bikes have no dealer paper trail

When a bike is bought direct there is no shop invoice, no dealer record and nobody to confirm the sale later. The order confirmation email and the frame number are the whole provenance. If you are buying one used, ask for that email. If you own one, save it somewhere that is not just your inbox.

## Buying a used Commencal

A clean-looking bike is not always a safe buy. Before you pay, ask the seller for a clear photo of the frame number and check it against stolen-bike records. You should also ask for:

- The original receipt or proof of purchase.
- The seller’s name matching the receipt where possible.
- Clear photos of the bike from both sides.
- A photo of the frame number.
- Any service history.
- Details of upgrades or replacement parts.

## Bottom line

The quickest place to find a Commencal frame number is underneath the bike, near the pedals. Look for a stamped code or barcode sticker, copy the full number, then check it before you buy, sell or register the bike. A used Commencal can be a brilliant buy, but the frame number is the detail that protects you.

## Frequently asked questions

### Is a Commencal frame number the same as a serial number?

Yes. Most people use frame number and serial number to mean the same thing. It is the unique identifying code attached to the bike frame.

### Do all Commencal bikes have a frame number?

Most Commencal bikes have a frame number or serial number. Check the locations described above first; on older frames the marking can be shallow or worn, so clean the area and check in good light before concluding it is missing.

### What if the Commencal frame number has been removed?

Do not buy the bike. A removed or damaged frame number is a major red flag. It may make the bike harder to register, insure, resell or prove as yours.

### Can I check if a Commencal bike is stolen by the frame number?

Yes. Use the frame number to run a stolen-bike check before buying. You should also ask the seller for proof of ownership and check that the details match the bike.

### How do I register a Commencal bike in the UK?

Find the frame number using the locations described above, then record it against your Commencal. It is free, and you need an account so we know where to send the alert. If that exact number is ever reported stolen to us, we email you. If anyone then lists a bike carrying it, the listing is hidden until the seller proves it is theirs.
