I ride a Vitesse D7 (wonderful small bike), it is one year old and did a lot of kilometers. I'd like to anticipate a bottom bracket failure.
Is it a standard BB ?
Can it use something like Shimano BB-UN53/54 Bottom Bracket square ?
In this case, what are the dimensions ? (I had this kind of BB on one of my hybrid bikes and it exist in various lengths 107/110/113/118mm and two case width (68 and 73mm)
