has anybody seen the handlebar tape? it's quite unique it's made by hutchinson for Motobecane, it is one piece of rubber that looks like a leather stitched handlebar, when you look at the brake lever rubbers you can see that al is integrated, the handlebar "tape" and the brake lever rubber are made of one piece.

this means in my opinion that the brakes are original, the 605 weinmann brakes
