Unless otherwise communicated on the websites of the single events, the Eroica rides are exclusively organized for Historical Bikes and for Vintage Style Bikes as explained hereafter.

Historical Bikes (also called Bici Eroiche in Italian) are all road racing bikes built in 1987 or earlier both with gears and without gears, as those built in the late 1800’s and early 1900’s.
These bicycles most likely have a steel frame, but also other types of rare frames are permitted, such as the aluminium frames built by Alan and Vitus with screwed or glued joints and the Exxon Graftek frames of the late 1970’s with carbon tubes glued to aluminium lugs.
Regarding the components the bicycles should be in line with the following general guidelines:
a) more recent bikes with gears and derailleurs, such as Simplex, Huret, Campagnolo, Zeus, Shimano, Suntour, etc. must have shift levers on the down tube of the frame; exceptions include pre-1980 non indexed bar-end gear shifters and rod/hand manual operated front derailleurs;
b) pedals should be with toe clips and straps or, for older bikes, as the original pedals; quick release, clip-less pedals are not allowed;
c) the brake cables must pass outside and over the handlebars (cables can pass inside the frame);
d) older geared bicycles should have original shifters such as Cambio Corsa, Cambio Paris Roubaix, Cambio Vittoria Margherita, etc.
e) wheels must have at least 32 spokes laced to a low profile rim (20 mm depth or less, except for the wood rims);  the rims must be of either steel, aluminium or wood;
f) both tubular tyres and clinchers with inner tubes are allowed;
g) we invite participants to fit saddles from the same period of the bicycles, so a model of 1987 or earlier, or a vintage model of modern production such as Brooks leather saddles, Cinelli replicas, San Marco, etc;
h) the change of the gear ratios is allowed due to the difficulty of the ride.
i) there are no particular rules on the type of brakes as long as they are in line with the construction period of the bicycle and that they are efficient for safety reasons
Of course, older road racing bicycles of the early 1900’s with single gear or flip-flop rear hubs don’t need to comply with the above criteria as long as they have their original components.

Vintage Style Bikes with steel frame from new or recent construction with vintage look and characteristics may be used only if they are road racing bikes assembled using vintage components or replicated parts similar to the original as described above. In particular if the bikes are inspired by the design of road racing bicycles of the 1970’s and 1980’s, they must comply with the 3 fundamental rules (a,b,c) regarding shift levers, toe clips and straps, and brake cables.

Exemptions regarding the type of bicycle will be granted to participants with disabilities, as long as they make a specific request to the organization at the time of registration.
For the 38 km route, other types of vintage bicycles will be admitted, such as postman’s bikes, general working bicycles, leisure bicycles, etc. as long as they were built in 1987 or earlier.

Exclusions: mountain bikes, cyclo cross bikes and time trial bikes are excluded from all routes.

Any registered cyclist who arrives at the start line or is found on the course with a bicycle that does not conform to the rules and regulations of the event will be disqualified immediately.
