hi! long time lurker of the forums.

i bought the wheeltop eds TX some time last year. it had failed & been replaced twice. both occasions failed due to water ingress. opened the rear derailleur and did notice some small droplets of water which ended up on one of the pins.
on the second occasion, it failed some 20 minutes before my Individual Time Trial. it was raining really heavily that time. really a big bummer & i have been using mechanical ever since.

i'm looking to re-fit my bike with a new set and in the future, for a gravel bike with the GEX groupset.

would like to know if recent versions have been weather resistant? my country is pretty rainy and humid (Singapore) and i tend to still continue riding regardless of the weather conditions.
it's a big concern for me and i'm hoping to give this another try!
