My Mondia Super came with a Suntour Superbe 52/42 front. Because the BCD was 144, the smallest ring I could buy was a 41 - hardly worth the expense.

I lurked on eBay for a while, and came up with a newer but still vintage Suntour Superbe crank set in 53/39 - mo' betta....

Plus, the BCD is smaller so I can futz with the ring combos if I want. I've got hills all around, and so far, so good. Not as good as a triple, but good enough.........
