Wow, Mark, your AO-8 is a gorgeous shade of green.

Hauk:

No idea what my '74 UO-8 weighs, no tools for that here, but i do really like it, even though the frame at only 60cm is way too small.

Mine also has period Sugino cranks, on a 3T spindle, with the original BB cups. Original Lyotard pedals, period Mikashima clips.

Weinmann 27 x 1-1/4 alloy rims, original Normandy hubs.

Upgraded Simplex rd, original Simplex Prestige fd.

Upgraded shift levers to cast alloy after I snapped off one of the plasticy ones a coupla weeks ago.

Long bar stem & seatpost, original bars iirc.

Original Mafac Racer brakes with salmon coolstops.

From todays sprint to the HW store and back:
