jojotut Posted July 8, 2020 Report Share Posted July 8, 2020 Can anyone help, building a Trifield but not sure what swinging arm to use. The frame is 1958 but the existing swinging arm will only allow a 17inch rear wheel. Any ideas! And does anyone have one. Thanks JOJOTUT Quote Link to comment Share on other sites More sharing options...
