80mm BCD outer/middle/inner 6 bolts
50.4mm BCD ring to crank 5 bolts
All the best,
my original post
'anyone have a ta specialities chainset dust cap/ track chain ring about,
got one dust cap need another as well as a 42-50 tooth track chainring'
I need a ta cyclotouriste TRACK chainring anywhere between 42 and 50 teeth. NOT a middle one, NOT the smaller one, NOT the one with holes to fit secondary chainrings..
As far as i am aware bcd is not important as there is only one size for this chainring that fits to the chainset arm. The only important thing is number of teeth and spacing of teeth in regards of the chain. I hope thats clear enough!
now look at the image link

that is what I want preferably with less teeth but larger rings considered..
