Just put an OMM rack on a touring rider's Bike * It uses a 135 rear skewer through the parts that go outside the dropouts

It's a Super rugged rack , it uses the hub axle QR, not the fork tip eyelets (you missing parts? )

Tubus Tara is a nice Low rider supporting rack , ChroMoly steel simple solid and pretty light for its load capability.

* a NY group of 7 sent theirs ahead, to be built up again.. to ride from here. many 520's different front rack choices.
