Are these rims the same ERD? (effective rim diameter)
Just about to rebuild with Open Sports as the MA3s are worn out and I want to use the existing spokes, but cannot find data on the OS.

Any help gratefully received!

Best wishes

    Spocalc has the MA3 ERD as 607 +3 for nipples. It doesn't list the Open Sport, but I saw somewhere that it is 611. The Rigida Chrina is 607 + 3mm. Why don't you call Spa Cycles, who build with both, and see? The Chrina is a bit heavier, but we've had good fortune so far.
