Crank teeth
I was cleaning my crank rings (FSA Gossamer 50/38) on the weekend, and
I noticed that every 15 teeth or so, the tooth looked like the tip had snapped off it. It was noticeably shorter than the others, whil still having a similar taper from bottom to top. It appears to have been manufactured that way. Question is... why? What is the benefit of having these 'shorter' teeth on your chainrings? Brendo
