I'm considering getting a rear rack and panniers (if possible) but I don't know what type of rack. It would go on my 1980 Sekai Limited. I'm going to be going to UBI for 2 weeks and staying at the cycle hostel and will only have my bike, so I will have to fetch groceries every so often. All the racks I have seen like in Nashbar catalogues, look like the one below. Where it connects at the eyelet just above the dropouts, then screws into holes on the seatstays.
My bike has the eyelets above the dropouts but no holes on the seatstays... What type of rack do I need to buy?
I can post a pic of my bike if need be.
