Here is someone who isn't going on internet fables, or hearsay, but actual real-life experience (sorely missing from the internet forumz).
I bicycle most of the year, except for hard Swedish winters (December to April), and ALWAYS have a rangefinder camera with me, either around my neck or in my bag. Most of the time an Hexar RF, sometimes lately a Leica M6. I don't have any shock absorber on my bicycle, not even on my seat, only shock absorption is the tires and my butt, and I have NEVER had a RFF miss-alignment on any of the cameras, not even the Hexar RF, let alone the bullet proof Leicas.
You are back from your trip now but If I could've put in my 2c, I would've said put that M4P around your neck, and let your thighs burn a little.
