A yakima highroad should fit it. Fits all my HPP bikes. I have a lot of time on the Privateer 161, druid and norco optic. My money would be on the new Norco Sight all around use. The optic is the fastest everywhere IMO yet still being able to go big. Just a harsher ride everywhere.
Being said as I do not have any money left after the above I have settled on a Morph cycles steel FS and hoping to build it soon. 140 or 160 forks. Keep the 160mm fork in a guncase for parks and racing and 140 mostly around tweed valley.
