Swap out the Bernard Hinault saddle for a Flite ti rail style saddle, add light weight alloy/ti skewers, swap out the wire bead tires for folding tires with thin butyl tubes and swap out the chainring and crank bolts with alloy ring bolts and ti crank bolts. Thats about 20 minutes worth of work and I have all of it on hand. I also have a set of modern ti axles but thats more work.
