My bikeposts were well received and I plan to do more, but I'd like to reach out as to whether there's a topic or maybe specific questions about the whole ordeal that interests the users of this site specifically?
Like do you want to learn about tools you need for more than basic maintenance? Tips on riding in winter conditions and/or in the street with car traffic? Maybe which of the marketing buzzwords are actually important? How to train for longer rides? How to bike commute / when to bike commute?
Hit me up, I'll try to answer any question and/or do another bikepost about any topics that you're interested in and I feel qualified to answer.
For chain locks (the kind with a metal chain with a nylon sheath and a separate lock), just keep the lock away from moisture at all costs to avoid freezing. The delivery-guy method of wrapping the lock in a plastic bag is surprisingly effective. If it does freeze, percussive maintenance usually does the trick to get it unstuck.
