I shall be riding the Koga-Miyata Gents Tourer 1977
From L´ Eroica website:
Only cyclists with "heroic" bicycles will be permitted to participate. 'Heroic' bicycles are road racing bikes, built before 1987 Gear shift levers on the down tube of the frame (exceptionally, only pre-1980 bar-end gear shifts are allowed)
The bike was designed for flat Dutch roads, built in Holland using Japanese built frame and groupset and I may have to do something about the gearing. The chainrings are something like 50/48 and the cassette is around 11-17.
I obviously need some vintage kit, and so far have come up with this jersey which has an early eighties look:
At least if something goes wrong the frame is guaranteed for life apparently.
