Ok, so in my defence, I was in an extreme rush to get a bike together out of spares for a mates daughter. Regardless...
Dragged my old haro sonix Frame out of the rafters to build up. Hasn’t been used in around 5 years, but that’s irrelevant.
Fitted some old forks, bars and a seat, just so I could sit it upside down (work stand broken).
Grabbed a set of ancient square taper deore cranks and a bb. Fitted the bb, and tried to fit DS crank with 2x rings. Fouling badly on the pivot that clamps around the bb shell on this frame. It was designed for 3x, but I assumed it came with longer bb axle originally. Not buying one, no time, so pulled off granny and 36t.
Fitted NW ring to inner mounts. Still fouling.
Fitted it to outer position. Granny tabs fouling.
Ground off Granny tabs, still fouling on chainring bolts.
Ground 1mm off head of pivot bolt. Still JUST fouling.
Ground 1mm off heads of inside chainring bolts. SUCCESS, just clears.
It’s a dog’s breakfast, essentially fucked the cranks, and and bolts, but they will hold. It’s for a young girl.
Time to fit derailleur and chain to see how bad the chainline is with ring mounted in outer position.
Hang on! Why are the brake mounts on this si......oh cuss!
