I have Shimano triple 9-speed grouppo (bontrager race lite pipe crankset) and I need to replace two chainrings on the crankset. I'd be willing to buy a new crankset/bb combo if it's cheap enough (say around $90 total), otherwise just the chainrings.
I have been dealing with these guys for years and know them personally (they are local to me here in VA). Their stuff is top quality and always very conservatively graded. No junk here whatsoever.
