Spinning rear wheel makes cranks rotate
Hi all, I have a Pashley Roadster Sovereign with a Sturmey-Archer X-RD5(W) 5-speed hub. Recently, I have noticed that spinning the rear wheel by hand caused the cranks to lazily rotate. This is true for both directions. Also, turning the cranks backwards by hand makes the wheel turn as well. Does this suggest a problem with the freewheel equivalent inside the hub itself, or is it possibly due to an overtightened cone? Is it possibly to accidentally overtighten the cone when retightening the axle nuts after tensioning the chain? What should I be looking into first? Thanks for any advice you can offer!
