Sorry, that's Aramaic to meGenerally a 22/32/42 for compact drive (94/56bcp)
Or 24/36/46 for ATB (110/74 bcp)
What crank did you get?
Sorry, that's Aramaic to me
I don't know the jargon, so please forgive me for the following.
I've dry fitted the chainrings to the spider and they seem to just sit in the correct place, evenly spaced.
I paid attention to the bolts' head grooves so the bolts would sit in them (other side of the chainrings is flat, no grooves).
Also I lined up those "prongs" with the crank arm.
Is this correct?
