I long ago gave up wondering about the logic of mixing so many kinds of threads and types of measurements (English threads, metric and inch increments, Italian threads, etc) all on the same bicycle, but the question that has me really stumped is this. Why does Campagnolo use such weird size openings on some of their bolt heads...probably other places, too. I mean c'mon...3.5mm in the Delta brakes? 6.5mm on the bolts holding the cranks onto the BB axel on C Record cranks? They must have known that not very many folks would possess such strange size tools. What could have been their logic behind this? Obviously they could have made or specified them any way they wanted. What am I missing about all this? Was this an effort to keep amateurs from
working on them?
