I'm not familiar with those two bike frames but I've seen a lot of low-end bikes with 130mm or even 135mm dropout spacing but with 7 speed freewheels. That's a lot of unsupported axle on the drive side. Think of the drive side cone as being the axis of a fulcrum and you'll understand why so many rear axles break. Oh, a lot of low-end axles aren't even Cro-moly.
