If you mean Cycles UK. They are open during prime commuting time in the evening. Nick from the store has said that this is their busiest time of day.
I always wonder if it would make any money for them if they were open a bit earlier/shut a bit later/both? I would have thought prime commuting time is over by the time they open and only just in full swing by the time they close. Surely a few more tubes/tyres/other kit might get sold if they were open when a load of potential customers were riding by?
