I took the fenders, dynamo hub, light, rack and basket off the Quickbeam. Also the S3X 3-speed fixed. It was pretty easy. I should weigh the parts that came off!
I put the +40mmSchwalbe on the front, but was too lazy to switch out the back. I like the tires, but the general lightening makes me want to try Rivendell Jack Browns or Grand Bois Cerfs.
You know, a “narrow” tire!
