The Classic Twelve.
The original twelve custom designs that have been on offer for the last thirteen years.
They are available in pretty much any tooth count up to and including 96t......the minimum number of teeth on the chainring will depend on bolt circle diameter (BCD).
I can machine these in almost every BCD ever produced.
My sample photos are of 5 bolt designs because they by far the most popular, but these designs are definitely available in three and four bolt patterns.
Some of the Details get lost as the tooth Count goes up. The shape and proportions change, depending on tooth count and the bolt pattern. I have some specific designs that are proportioned for bigger sizes above 60t .
