Could have been used for Randonnée, but really just a sport touring bike, as most were in the early 70s. To take wider tires and mudguards. Nothing specific about it to call it a Randonneur. Should be a nice all-around bike.

Here's a Carre bike I got a few years ago that was quite odd. The head angle was 70.5 and it only had 38mm of fork offset, producing a whopping 80mm of trail. I'm sure it was made this way, but I can't figure out why. All I can guess is, he wanted to give it some toe clearance, and it had a 54 cm top tube, but he didn't bother to pair it with the right fork. Steering was very heavy and I could not ride it down the road no hands. Too much "wheel flop". I added 17mm of offset to the fork, which shortened it, steepened the head angle, and also gave the top tube a slight slope, but now it has trail of 58-59 and handles perfectly, hands on or off the bars. I'm afraid I lost a bit of respect for this otherwise highly regarded builder, to have turned out a bike with such impossible front end geometry. Last pics show it after the modification.
