Hairline cracks on rim (pictures)
I have an old 28H Araya ADX-1 World Champion front rim from the late 80's that has developed very small cracks at the nipples. I will eventually replace the rim, but in the meantime....is this safe for track races? No sprinting, just going around fast. I weigh 155lb and the track is 33 deg with some bumps. There are about 4-5 cracks, I took pictures of the biggest ones
