Ergon website doesnt have replacement screws. Any ideas?:oops: June 2, 2013 at 19:51 #119599 Jampa56 I meant GP3 June 3, 2013 at 05:22 #119600 schwim ✓ supporter I can’t even find them for the GP3 on the Ergon store. If you can come up with the specification of the bolt(length, diameter, thread), you could buy one that way.
