Custom Oak Cycles 650B French Randonneur Project.

The upside down Edelux is specially made with inverted optics (at the cost of a rear light relay and the low light switch). I don't think the IQ Cyo is available for upside down mounting so your beam would be all wrong.

Thought that might be the case. Will have to look into another way. I'm loathed to pay the £4 for what looks like a fairly ineffective solution from the VO bracket.
