Oh no - Eroica has loads of regulations, but, as I figured out about most things Eroica South Africa, they are mostly guidelines... 1 - If you ride a pre-1987 racing bicycle… 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, original vintage pedals - quick release clip-less pedals are not allowed;c) the brake cables must pass outside and over the handlebars (referred to as non-aero brake levers), and not under the bar tape (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 (20mm depth or less, except for the wooden rims), and 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 their bicycles, or a vintage model of modern production such as Brooks leather saddles, Cinelli replicas, San Marco, etc.;h) the changing of gear ratios are allowed due to the difficulty of the ride;i) there are no particular rules on the type of brakes used as long as they are from a similar period to the bicycle, and that they work efficiently for safety reasons. 2 - If you ride a pre-1999 racing bicycle (a special South African category)…a) bicycles must have shift levers on the down tube of the frame; or bar-end gear shifters;b) pedals should be with toe clips and straps - quick release clip-less pedals are not allowed;c) the brake cables can pass under the handlebar tape (referred to as ‘aero brake levers’), along the handlebars;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;f) both tubular tyres and clinchers with inner tubes are allowed;g) we invite participants to fit saddles from the same period of their bicycles, or a vintage model of modern production such as Brooks leather saddles, Cinelli replicas, San Marco, etc.;h) the changing of gear ratios are allowed due to the difficulty of the ride;i) there are no particular rules on the type of brakes used as long as they are from a similar period to the bicycle, and that they work efficiently for safety reasons.
