Not sure exactly when I bought them but it was certainly sometime in the mid to late 80s I bought the exage aero levers that were on my Gran Course till I tweaked it for this ride with a set of Golden Arrow levers. Also looking a photos of early to mid 80s bike races looks like aero brakes were certainly starting to appear around 83 or 84 and by 87, the cut off for eroic bikes, were pretty much the normal kit on pro bikes. So I think if they were running early aero they were certainly period correct if not within the letter of of the rules. Unlike the Lush cosmetics crew! While they did have some great old bikes there was a Triban 3, one that looked rarther like it was full carbon and even a mountain bike!
