perfect for Garmin Edge 510

My Garmin Edge 510 bike meter locks perfectly on this bracelet. Bracelet very good. comes with also with bike mount and screwdriver (not useful for the 510).
By cons will not be using your Garmin 510 to give you instant speed running, it only varied, I think the arm movements prevents the speed to stabilize ....

So a very good product at a great price considering the quality.
