I talked to my LBS and they mentioned it would be hard to find a chainring that would fit my bike.
What stores online offer older-styled Chainrings?
It's a 5 bolt hole,so all you really need is the BCD and the rest is easy. Your LBS is full of morons too.Measure C_C of adjacent bolt holes. 110bcd = 64.7mm, 130 = 45.3mm, 135 = 79.5mm and 144 bcd is 84.6mm. If it turns out to be 144, I have some for pretty cheap.
