Mount your cyclometer on your Triban or Van Rysel bike!
The BC900 cyclometer is compatible with the "Dashboard System" which can be found on certain Triban and Van Rysel road bikes. Thanks to this technology you can mount the cyclometer straight onto your bike's stem! (available beginning September 2020)
We know that your personal records are precious. This is why the BC900 automatically detects your records and stores them in its memory. Whenever you beat a record, your cyclometer will congratulate you.
Height: 14 mm
Screen: 38mm x 31mm
Customise your activity screens
You can customise each activity screen (the pages on the cyclometer that you see when riding). For each page, you can choose:
- the number of fields (values): between 1 and 5 (the size adjusts automatically so if you want bigger numbers, don't have too many values per page)
- the type of value for each field
- the number of pages (up to 9 pages)
These settings can be adjusted on the cyclometer or even more easily on the Decathlon Connect app.

Indoor use (turbo trainer)
Want to use your cyclometer during indoor turbo trainer sessions as well?
The cyclometer has an "indoor" function that lets you use it without GPS. You will of course need sensors to give you your speed, cadence, heart rate or power data. (sold separately)
Does the BC900 cyclometer provide navigation functions?
No, the cyclometer only records your GPS track for you to view on a smartphone after syncing. The cyclometer has no navigation function.
