I also like the Victory cranks (in particular, because there was a (rare) 175 mm long version of it for ATB use that can be used on a road bike, too, of course, and I'm a 175 mm user).

Miche makes a 116 BCD five-arm 'junior' crankset, but so far I haven't been able to find a good source for just the rings, plus they don't go any larger than 48 teeth, and Miche also told me that the rings are a fairly low-strength alloy, as they are designed for 'kids, not adults....'
