Yes! InfoCrank has passed the IPX7 waterproofing tests. If you wish, you can submerge it in 1 meter of water for 30 minutes. You obviously won’t need to do that, but riding in the rain, through puddles, or washing your bike won’t damage InfoCrank. 

Regardless, we advise not to use a pressure hose directly on the InfoCrank power meter! Best to clean it gently, with some TLC.
