Having just bought my second Campagnolo 36t chainring in less than a
week ($10 no less!) we seem to have skipped over the fact that Campy did
do a tripple with a small inner ring that was not attached to the 144
bcd holes but to a set of drilled 100 bcd holes on the spider itself.
other alternatives would be to drill to one of the current bcds for a
more complete range of rings.
more alternatives would be a tripplizer ring which attaches a second
ring to the inner 144bcd (I have a Merz version which does TA
cyclotourist down to what 26T)
