I like the idea of 5 vis cranks, and would love to use one for something suitable to my fitness and riding style like a 42-28 double. Alas, the only 5 vis crank I have is a Zeus Competition with 52-45 rings, which most definitely do not mesh well with my fitness or riding style and seem like a fairly odd choice for the sport touring bike they came on (1969 Raleigh Competition).



I toyed with the idea of trying to drill out some 50.4 chainrings to work with this crank, but it doesn't seem like a reasonable direction.

I wish there were more reasonably priced modern options for 50.4 chainrings. Being the inveterate cheapskate that I am, I find it hard to buy replacement chainrings for any crank, when a new crank with the gearing range I want is usually nearly as cheap if not cheaper.
