Love your Peugeot rebuild and modification. I love old steel 10 speeds. 27" x 1 1/4" wheels and tires are still readily available. You can also run 700c wheels in this frame with possibly a brake caliper change to a longer reach but maybe not. I'm very tall and like higher bars even on the larger frames. I don't use drop bars anymore. This is just a lovely old bike ready for many more miles of fun.
