Raleigh Grand Prix chain and rear hub keep turning when coasting

  • If you do this, do you hear a clicking noise as the wheel turns? – Carel May 25 '19 at 13:26

    Assuming you have a freewheel, you can try lubricating it. Worst case is having to replace that freewheel. This may seem like a dumb question, but can you confirm that you have a freewheel in the rear? Alternatives would be a fixed gear or the short-lived Shimano "front freewheel" where the pedals remain motionless while the chain and chainrings keep turning during coasting. – Andrew May 25 '19 at 13:30
  • Stupid question: Do you have a freewheeling crank? Some bikes are designed to work this way, as it makes shifting easier, especially for the novice. – Daniel R Hicks May 25 '19 at 23:45
  • Clarify please : Do you have a rear derailleur and a multi-cog cassette at the back? Could be a fixed gear conversion. – Criggie May 26 '19 at 0:15
  • Clarify - if you're riding along and you stop pedalling, can you push down on the rearmost pedal to have it coast normally, or does the pedal push your foot around in a circle no matter how hard you resist it? – Criggie May 26 '19 at 0:16

When you stop pedaling the freewheel on the back wheel is supposed to spin so that the wheels can keep turning but the chain, and the pedals are stationary.

Something is preventing the freewheel from doing it's job.
First guess is that it needs lubrication.

Repair Options:

  • Pull the rear wheel off and try working a little oil into the freewheel. This involves turning the freewheel backwards while applying oil in the gap between the moving part of the freewheel and the stationary part.
  • Disassemble the freewheel and lubricate
  • Replace the freewheel. This will require a special tool, your local bike shop should be able to help you. If it's off the bike some will remove the freewheel for free - others will charge.
