not sure

easy to read and use

may not calc for my bike size

I have the btwin triband 48 cms (650) and im not certain that the count 8 may go low enough to calc my smaller bike size. Hoping to find out this weekend. This is great wee computer but it should be able to compute for all sizes.

Response of the brand


You should be able to enter the circumference of your tyre with no difficulty as the computer works on 26" MTB wheels with no problem (similar to 650 wheels on your triban)

It is compatible with your wheels. There's no need to worry.

If you want assistance inputting this data, please feel free to contact your local store.

Excellent large display, easy to use, easy fit


A really good product, very easy to install and very accurate. I really like the large display, makes it so easy to see on a ride.
Better than most branded products at much higher prices.
Decathlon really do have bikes and accessories well sorted. Hats off to the team from a happy consumer.
