I am doing L'Eroica (205km) in October this year. The chosen (pre-1987) bike is a Colnago Super with super record group set.
Issue - the chain set is 52/48 (i.e. road set up) and even with the highest sprocket rear block (28) i can find, I will be walking up more hills than I would like, which with old style shoes and cleats is not good for comfort or time.
Talking to Spa cycles in Harrogate, they inform me that there are no lower chainring options for the SR group set - their solution (quite good) was to remove the SR chainset and for this event, use a cheap (£34) stronglight compact (48/34).
This lack of "period" chainset is niggling me - I wondered if there were any grey beards out there who might have another take on this? Surely there are campag chain sets that were made with lower ratios?
