Cycle wing placement ( have I got this correct)

[MarkB]

Get a big squarey thing and put it up against the rim at the front, the wing sits at this point then the rear will be on the centre line of the wheel. If the wing is too far round then it will throw stones and allsorts of other nasties that might be in the road up at you...last thing you want is horse or cow dump in yer fizzgog let alone a stray stone
