The shifting is notchy enough in temperate days, below freezing, close to zero out, I can't get it moving, as if the lockout button is frozen and can't push it all the way down, I've gone so far as tap (gently) the button with a small hammer while trying to move the lever, usually, once I go thru the gears once, I have the strength on my thumb
is there something I can spray WD40 on ?
