You probably know this but I think there is a TA triplizer adaptor for this so you don't have to drill if you like -consult Sheldon Brown's info on Harris Cyclery. Then you can always go back to a double without scars. There is another less expensive adaptor too,highly adequate they say, but I am told the TA rules.Having a 53/42 SR front, I considered the above but for now have just increased the rear to a max cog of 34.I gained more climbing ability than I would have imagined.

I own both Campy NR 144 bcd 5pin and TA Cyclotourist 6pin cranksets. I want to add the triple inner chainring drill holes to both of these crankarms.
Does anyone know what are the appropriate metric tap sizes to properly thread the bolts for either Campy 36T or TA 36T inner chainrings? I have all the parts needed to accomplish this but having problems finding the proper thread sizes...
Thanks, Steve Neago
