Built this up using Raleigh wheels and bottom bracket. Mongoose stem. Giant 5 speed derauiler and cassette. Added 3 inches to the seat stem. Disc brakes both ends.
My vintage Schwinn drum brakes barely work. I have no experience with drum brakes, but the concept is simple. I have installed new cable and brake shoes. Drum had some interior corrosion but not to bad. Performance is lousy> any suggections?
