On Proti's website they are now showing drilled bolts FYI
Not if you shop by bike. I went to the K-67 page. Previously purchased Race Spec from Pro bolt for the HP4. Just had to look at past orders for links for what was needed for the K-67. Both sites should have links to race spec bolts when searching bu bike.
