Whoops, egg is on my face. TA Cyclotourist is a 6-arm chainring. It can be used to make other BCD's for 3-arm chainrings, such as TA professional (which is what I was thinking about when I wrote the email) but its use for 5-arm chainrings would be highly questionable ... :-( :-(
Does some manufacturer make a "generic" 5-arm chainring with a really long and wide _undrilled_ arm that runs from a small bcd hole all the way to the toothed edge of the ring ?? For example, Stronglight Escapade ??
