Over and over I've said this - whenever you order Tomos Piston rings, ALWAYS ORDER DOUBLE.
It's just too flamin easy to break them when you put them in, and even I snap em on occasion, so be prepared, and always order two sets instead of one, and you don't wind up in this situation...
So Matt ? order FOUR, not two, rings this time, ok ?
Take your time, be patient, but above all, be prepared.... especially with the A5(A35) rights, since they're even thinner, almost wisplike, and snap even easier than A3 rings.
Always, always, without exception, order double rings for Tomos, ok ?
