I just received a set of new sisl2 arms. They are a few grams heavier than my original set. The first ones are 124 grams each for 175's. Here are some comparisons also including 2 regular SI's i was replacing. These are both 172.5. Something to note my compact spidering is 155, my old USA MK V set is 142 but they have some wear.
