Garmin speed/cadence sensor waterproof?

[Thinkbeeg]

Are Garmin's speed/cadence sensors waterproof?

Do you take it off each time you wash your bike or do you just leave it on?

 

Thanks

I left mine on and it broke so garmin replaced it and it broke again so i just took it off.

Thanks! I guess I'll take it off before each wash.

Just pull a small bag over it...and fasten it with an elastic. Work's for me.

They're supposed to be waterproof, but they're not.

 

If you remove the sensor and pull off the rubber 'foot', you will see a small hole in the bottom of the sensor housing. Water gets into this hole and corrodes the circuit board.

 

You can fix the problem and make it properly waterproof by using some silicone sealant to plug the hole.

 

I've noticed that newer sensors come with this hole already plugged.

I have the same query, just for a Sigma 2209 cadence and speed sensors. Anyone know?

I've never had a problem with my cadence/speed sensor.

 

Whether the small hole that's been referred to in an earlier post is sealed or not, I couldn't say.
