I recently bought a pair of Qbicle Tangent fenders for my folding bike. The bolt for the derailleur hanger is in the way of the mount:
The fender is supposed to be installed at around this angle:
The derailleur hanger looks pretty much like this:
And the dropout is just flat (no grooves) with a hole beside it like this:
Is that derailleur hanger the only type of hanger that can be used for that kind of dropout?
I could install the fender so that the bolt of the hanger would pass through the fender mount. The fender would be mounted at around 170°; it would just cover the area between the 9 to 11 o'clock positions. Would the fenders be useless at that angle?
