We will be in touch
need a replacement wireless cycle computer for use on a basic cycle trainer, nothing fancy or expensive, able to fit on rear chainstay.
Previous one was a wired one with head set mounted on top tube, not ideal.
What information are you wanting?
Just speed or cadence as well?
If it’s just speed, you can’t really go wrong with a cateye velo
