Rack Mount Bolts allow the addition of a rear rack to any Esker bike using the Portage Dropout system. Additional threads within the extension bolt allow racks to be mounted to the bolts from the outer side. Includes 2 bolts.
Rack Mount bolts act as a stand-off from the frame for mounting a rear rack. They are broached for 8mm Allen just like the standard hardware, but are also center tapped for M5 (standard rack size).
NOTE: If your Esker frame doesn't have built in rack-mount bolts on the upper portion of the seatstays, you'll need a seatpost clamp with rack attachments like THIS ONE.
