• There's some discussion in the YACF thread linked above about the advisability of trying to waterproof USB connectors. Igaro's take is that it's better to let water drain out; they've also made the port on the D1 replaceable, as they reckon any one used in all weathers will eventually corrode. This is inherent to the USB spec - the pins are too small and closely spaced for robustness against the elements.

  • Replaceable, but a hassle to do so depending on how you feel about glue guns and soldering irons.

    @gillies The two guys I installed for are both heading to TCR, so want absolute reliability or as close to. Only one's stopped charging so far after two 300k rides, so not sure what the issue might be, I was willing to investigate, but the guy decided to send back to Igaro.

    The USB connector had a fair bit of rust, but I wouldn't have thought this would have been an issue electrically. I would personally try any options to help (paging @hippy for his idea). Simplest would be to leave the USB end in a TT mounted feedbag and use when needed.
