Finally opened up my Helix to lubricate the pedal...
...and found that one of the shoulder washers (the cylindrical ones that go around the bolt, with a perpendicular flat section) had actually broken.
Where the heck does one get replacements for it? I don't even know what precise size it is as it seems to be metric, so I can't just order it online.
And FullCompass does not have them.
Help!
