You still owe me that tenner after you declared bankruptcy 


they would probably just hand it over to a debt recovery firm and the op could end up with a CCJ, etc
Highly unlikely

Is there any limit of time a previous employer can ask for money which they have just discovered that I owe them?
I left over 9 months ago and have just now recieved a letter saying I owe around £100. Can they legally ask for this money back after so long?
Am I the only person who'd pay up? It's £100, not worth the potential aggro over it all otherwise.
Depends on personal circumstances. If I was strapped, I'd string it out probably.
While true, he specifically signed a contract that has this clause:
Cyclescheme:
"Once signed, the Hire Agreement is non-cancellable following a cooling-off period of 7 working days following collection of the goods. This means that if an employee leaves or is made redundant from their employment during the hire period they are obliged to pay the remaining salary sacrifice amount in full from net pay i.e. without any tax exemptions."
