Koga Miyata Gentsracer Aeroluxe

Hi,

Approx £375 in 81/2?

i guess you could call them roller-cams, although they miss the roller part. still, the principle is the same as with roller-cam brakes.

these brakes were one of the distinguishing features of the "shimano ax" groups brought out in 1981 - there were two, 600 and Dura Ace, which were quite similar to each other (actually, there were three - the third was the low-end "adamas ax". i don't know much about that one)). other features include the first "aero" brake levers with cable routing under the bar tape, and the special "DynaDrive" Crank and Pedal system, where the pedal has no axle and the bearing is located in the cranks.

the groups belong to some of the first steps of designers trying to improve the aerodynamics of bicycles. at the time, they weren't very successful (imho, he group was discontinued in 1983), but today the nice aesthetics and the historical significance has given them their share of recognition.

I have a scan of the 1981 catalogue showing your bike as was made.
But I need to fique how to post it?
