Ive just bought a used 1999 Diamondback Interval and used it (tried to!!) yesterday for the first time. The trouble is is that whilst when i change gear it shifts into the new gear, when i freewheel or stop at a junction, when I go to pedal again, I have to pedal three or four times round before the gear kicks in. Why is this doing this? I nearly came off within 200 yds when i stopped at a junction, went to pedal away and nothing,...just spinning on its cog for a few revolutions before the bike got going.
Can anyone help please????
