NOS D-A AX brakeset - includes levers w/hoods, cables and rare rubber aero cable covers.
NOS D-A AX hubset - 36-hole hubs w/skewers and 12-21 7-speed cassette.
NOS D-A AX pedalset - includes pedals, toe clips and original blue AX toe s traps.
NOS D-A AX front derailleur - braze-on.
NOS D-A AX rear derailleur
NOS D-A AX front derailleur conversion clip - very rare clip allows convers ion of braze-on derailleur to clamp-on style.
NOS D-A AX Owner's Service Manuals - very rare and seldom seen set of fou r booklets that covers installation and adjustment of D-A AX components.
NOS D-A EX headset wrenches - special profiled wrenches needed for the head sets spec'd for the AX group.
Many thanks.
