Why does my bike not shift into 1st gear?
You might also experience not being able to drop into the smallest cog if your cable is too tight. If this is the case, then loosen the cable by turning the barrel-adjuster on the cable in. Here’s a decent tutorial: http://www.madegood.org/bikes/repair/set-a-limit-screw-on-a-rear-derailleur/
Are there any gears that don’t shift?
All gears shift smoothly, but won’t shift into 1st gear/large cog. Help? So I was tuning my newly acquired bike today and working with all 8 gears on the rear derailleur.
How can I Shift my derailleur to highest gear?
If it’s at the maximum you have to shift to the smallest cog (highest gear), screw the barrel adjuster all the way in, unclamp the cable, pull on the cable as far as possible (pliers help) and then clamp it again. If the cable tension doesn’t help you have to turn the L screw counter-clockwise to allow the derailleur to move farther.
How often should you loosen the derailleur on a bicycle?
I’ve never experienced a derailleur that didn’t have one or both unwound somewhat. The “L” or low-limit screw should be loosened (counter-clockwise) a 1/4 to 1/2 a turn a time. You should see the derailleur respond when manipulating the L screw when your chain is in the position of the photo: the low-gear side of the cassette.

Why does the rear derailleur not stay in gear?
It’s a 12 speed with the gear shift on the lower bar. The rear derailleur seems to work, that is it shift from the small sprocket to the largest, but it will not stay in anything beyond the the small one. I have replaced the cable and adjusted the high/low as in the video (thanks) but nothing is working, it will not stay in any other gears.
Can a rear derailleur work on a 12 speed bike?
Hi, I have an older road bike. It’s a 12 speed with the gear shift on the lower bar. The rear derailleur seems to work, that is it shift from the small sprocket to the largest, but it will not stay in anything beyond the the small one.
