Bike Anti-Porn - When Things Go Wrong

What are you measuring? It's 43.5mm to the midline between the two road rings, which is close to the outer face of the spider thanks to the dished outer ring. That gives me ~46mm with a 4mm thick symmetric track ring, but it would be less with a thinner ring and no milling of the back of the crank.

Something just doesn't add up. I've measured the chainline countless times, from the center of the chainring teeth to the center of the seattube/downtube, also measured the diameter of the ST/DT, divided that by two and added the distance from the chainring teeth to the corresponding tubes, got 48.5-49 every single time. I'm using a symmetrical 4mm velosolo ring FWIW

I'm quite interested to know how (&what) they got the brake on the scatto :/
bar end lever.
