The Le Tour is a very good bike. I have rebuilt them, ridden them, and gone on tours with people who ride them.
The frame is lightweight butted and lugged chro-moly. All the components are good quality Japanese made. The Le Tour was a bargain in the '70's and 80's and just made it under the wire before bike manufacturing went from Japan to Taiwan due to cost considerations.
Take the Le Tour and thank your friend profusely.
