Can all be backed up with MapMyRide and Strava (which I migrated to at the start of April) with which I have religiously recorded every single mile.
I’m not sharing, because I don’t feel the need to and have nothing I feel I need to prove to you.
I think that unfortunately the more visible corrosion on the chain etc would lead anyone to think that the bike just hasn't been that well cared for - chain maintenance is pretty straightforward but it does need to be regular otherwise even just 1 wet outing can result in a nasty, rusty and stiff chain. Not terminal but certainly reduces the life of it if it isn't addressed before its next use.
That then sets up the shop to claim that other issues are linked to lack of care. The hubs really should last for a few '000 miles unless they are cheap crappy ones or the seal, as already mentioned, has been compromised.
If you've been over generous with the use of WD-40 or similar and it has got past the seal , or used a pressure washer enthusiastically then that would explain it otherwise the hub should not look like that this early in it's life.
