• Its the same connection that you have at your RD, and I imagine they must get occasionally submerged in water with the more adventurous riders. I guess those connections would be rated for at least IP-spalshy-proofy (cant be bothered to look up the exact codes).

    Cleaning out the connection wont hurt though, if it resolved your issue then you've got your answer, and you can consider silicon...etc

    PS: If anyone got a spare DN-110 battery they want to sell, let me know!

  • It’s more about preventing future issues. It’s been years since I had a bike without guards and I’d forgotten just how much water and crap gets thrown up against the top of the seat tube esp during off-road stuff.

    Good point about the other junctions at the FD and RD.

    I’ll take the post out and see if there’s any sign of water getting in there for a start.
