Premium Member David DuMond sent us today’s QT, a remedy for a situation that, as he points out, often indicates an adjustment is needed to your front derailleur. Here’s what he wrote:
Clink. Clank. Oops. Dropped your chain off to the right while trying to get on the big ring just as you are beginning a downhill? Possibly a poorly adjusted front derailleur, or you made to hasty a shift. Either way, you can recover without grinding to a stop on the hill.
By this time your chain is likely hanging on the crank axel at the base of the crank arms and just sort of sitting there doing nothing while you are trying to pedal. First, keep pedaling — slowly (note, slowly). Watch to see if the chain re-engages with the teeth on the big ring.
This sort of multi-tasking on a speeding downhill bike may more than test your resolve. If you really need to, stop.
If the chain and teeth don’t get together properly, continue to pedal slowly (again, slowly!) with your left foot (assuming it is clicked into the pedal).
Unclick your right foot from the pedal. Use the inside ball of your right foot (inside edge of shoe sole) to lift up the chain from below while holding the foot gently against the slowly turning chain ring. Push the chain up and hold it until it catches teeth. Keep pedaling slowly until the chain stays on over a full rotation. When you stop for a break, check to see if your front derailleur is out of adjustment.
This can be done while riding in a group, even, once you get the “hang of it.” However, if you get the hang of it, chances are that your front derailleur is out of proper adjustment. So make sure you address the root cause of the problem.
If you have an idea for a QT, fire away. We’re always looking for good info we can share with fellow roadies. We would love to hear from you with any suggestions you have. Contact us by clicking Quick Tips Ideas.
