Alright, finally down to business... a post about bikes!
An inconspicuous but valuable part of the Dahon MU SL set up is the little magnet that keeps the frame folded when being carried. However thanks to the fast but firm ride offered by the high pressure Schwalbe tires and lightweight Kinetix Pro rims, that little magnet can rattle a bit on rougher terrain. This can rankle a little or a lot, but the worst case is when you are cruising by impressed onlookers, showing off your sweet ride, only to hit a rough patch and sound like a dissident shopping trolley in a gravel patch. It must be silenced!
So first off, nick one of the missus' hair bands (or your own...)
Then push the magnet in, against the spring, lift up the washer on the reverse side, and slip the hair band beneath it.
Release the magnet, and pull the washer up on the magnet side, beneath the spring. Loop the hairband under this washer.
And now you're done! No doubt a more professional (and probably permanent!) solution would be to use rubber washers... but eh.
Now jump back on yer bike, and zoom past those slack-jawed tourists as they witness a slick, silver blur purr sexily past them.
