I won a dahon curve d3 on ebay advertised as brand new. It arrived in a beat up box with holes in it, no padding, scratches, scuffs, a very small dent in the top tube, and a bent chainring with a missing retaining screw. I can live with the cosmetic blemishes but the bent chainring, rendering the bike unrideable, is problematic. Of course, I'm going to notify the seller but I just wanted to ask you all advice on replacing the chainring. It's a 46t and bolted on with 5 phillips head fasteners. Can I just replace the chainring with a standard 46t? Do I need to pull the cranks to get the chainring changed?
I'm just trying to figure out whether it is worth messing with or if I should just return the bike.
