It really doesn't take much to break some combination locks.
It sounds like yours is one of the types that have the signature give as each digit of the code slides into place.
Even without this, chances are people leave combination locks relatively near to the code that unlocks it, vastly reducing the number of combinations that you need to enter.
I'd buy a decent key D-lock, if I were you- especially in Cambridge, where the high student population means bike thieves have plenty of practice.
But excellent news on the bike coming back- naturally I would not have posted the above prior to the successful return of a bike.
Having had a bike stolen and returned I know what a great feeling it is!
