Direct Mount Adaptors for Switch Rack are designed to fit all bikes with horizontal/in line M5 rack/mudguard mounts. All mounting hardware is included.

Fitting the Direct Mount Adaptors:

Direct Mount Adapters are designed to be compatible with frames which have horizontal / in line M5 mounting positions on the dropouts
They can be installed onto frames with M5 mounting points on the seat stays, but it is important to ensure that these are horizontal and in line to avoid the rack from binding during installation
Direct Mount Adaptors are not designed to be compatible with frames which have M5 mounting positions angled upwards or inwards
For frames with 135mm and 142mm axles, set the adaptors so the short end is seated within the rack mounting point. For frames with 148mm (boost) axles, seat the adaptors so the long end is seated within the rack mounting point. 
Place the rack/adaptors over the frame and use the provided M5 bolts to secure. 
M5 bolts are provided in two lengths, 40mm and 50mm. The correct bolt depends on the spacing and thickness of the dropouts on your specific frame
It is important to ensure that the bolts used do not protrude more than 3-5mm from the inside of the dropouts when installed. This is to avoid any potential interference with your bikes disc brakes rotors or drivetrain

Completing fitting the rack:

Ensure the rubberised fabric strap is tightly wrapped around the seatpost or seat tube
Use velcro strap to tightly secure the seatpost/tube mount
Tighten all bolts
