  1. Just got my brand new 20in wheel with built in SON hub dynamo for my StreetMachine hmmmm! I have
    noticed as I try to spin the wheel holding it in my hands it feels very very notchy and assume this
    is the magnets, i didn't expect this, is this normal? Does it disappear with speed as it feels there
    is alot of resistance when i spin it slowly. I was expecting it to spin quite freely at any speed
    but until i mount it on the bike, I guess i won't really know if the notchiness or resistance
    disappears. Has anyone else experienced this?

    It's fine. I recommend searching groups.google.comgroups.google.com for a thread that I started last December
    headed "Schmidt hub bearings".

    My wife almost fell off her bike in fright the weekend before last, when a dog with its head out the
    window of a passing car barked in her ear
    :-(

    Yes, yes (at about, oooh, ~1 km/h). I never notice it's there except when the road gets a bit
    brighter in front of me. Don't worry, it's a superb piece of kit and I doubt you'll regret
    getting it.
