Ryder Computer Problem

[divan]

Hey

 

On my road bike I have a Ryder F-09 computer but lately it has become problematic. Everytime I reach 30km/h it just stop reading the speed(reads 0). When I reach a hill/slow down to under 30 it reads the speed again.

 

Any idea what could cause this? It's quite irratating because I used to keep details of my sessions but am unable to do so now.

 

Cheers
