• i've got a newish 1/8th (<500 miles); stronglight track chainset, ring, bottom bracket, 18t sprocket, wheels.

    the difference in tightness is about 1 inch of slack (pull up then pushed down) to being tight on different parts of the ring.

    is this ok or too much? i'm worried about the chain coming off at 150 rpm and getting hurt / killed.

    i've tried the sheldon thing and it made no difference as the ring is a tight fit on the spider.
