Newbie to the list I will come back with a short - very short - introduction. Found this list when I posted to questions to the bob list and was directed hither. First one - made actual by the ongoing Campa crank thread - is:
Rummaging a small Stockholm bikeshop couple of weeks ago I found some peculiar Campagnolo cranksets. They look in style like old Nouvo Record, fluted and milled, but with three pins to hold the chain-wheels instead of five and stamped with Campagnolo Strada on the backside. Two sets were just 150mms ( and hadn´t my children bee too old they would have got something very cute ) with double chain-wheels, 45x38 and 42x36: these had normal NR bolts. Two were 170mms for singles, one - that I bought cheap - with just a 36(!)chainwheel, one with an adapter for a double, those had non-countersunk bolts. Bcd - as I measured with a ruler - is 115mm except those on the adapter who are bigger, but still 3-pin.
What is this? Someone knowledgeable, please explain.
Dangerous thing, bike shops.
