I have a somewhat unique situation in that I do not have a garage or a carport, but I do have a small barn.
I plan on upgrading to a Marin Presidio 3 soon. There will probably long periods of time (say 2-4 weeks) where the bike won’t be ridden. The challenge of a barn is that things tend to degrade in there unless they are protected. Lots of dust/dirt, spiderwebs, critters, that sort of thing.
Looking for an suggestions of how I can store the bike to minimize damage from the immediate environment.
The 2-4 week periods are nothing. Just wheel it in there, secure your barn best that you can (this is your biggest concern), and otherwise move on with your day.
It’s when you store it for long periods, that you need to think more strategic. And that really just means somewhere dry. I have to overwinter my bikes for instance, so they just come in the house and lean against the wall, and other than having to pump up the tires, it’s completely in the same shape as it was six months ago.
