How do I adjust the rear derailleur on my bike?
Hop off your bike and do this: Shift your chain into the biggest chainring and smallest cog, then loosen the cable clamp bolt (where the cable attaches to the derailleur ). Leave the derailleur in the smallest cog and adjust the high limit screw. Push the derailleur in the largest cog and adjust the low limit screw.
Why does my chain slip when I pedal hard?
Most of the time, a skipping chain is caused by cable stretch. In the first half dozen rides on a new bike your shift cables stretch the most. They can also stretch over time as you ride. Hippley explains, “It takes cable tension to open a derailleur, which shifts your chain between gears.
How do I adjust my bike shifts?
Here’s how to do it:
- Step 1: Shift into the smallest gear. I also like to drop my cable tension as low as possible.
- Step 2: Adjust the high limit screw, usually marked with an “H”.
- Step 3: Tension the cable properly.
- Step 4: Carefully shift up into the largest gear.
- Step 5: Fine adjustments.
Why is my derailleur hitting my spokes?
It is possibly bent/tweaked and the only way to know for sure is to put an adjustment/alignment tool on it and check. If it is it is generally and easy tweak to put it back in alignment, then realign/adjust your rear derailleur.
What gear should my bike be in?
When riding uphill or into a headwind, it’s best to use the small or middle front chainring and bigger rear cogs. When riding downhill, it’s best to use the bigger front chainring and a range of the smaller rear cogs.
Why is my bike not changing gears?
Stop shifting when you find an issue, but keep your bike in that gear. Loosen your cable adjuster if the chain won’t shift down. If you need to make a large adjustment, thread the adjust into derailleur, shift into the smallest gear, loosen the pinch bolt, and pull the cable by hand.
Do you shift gears while pedaling?
Rule 1. You must be pedaling when you change gears. If you click the shifters without pedaling, the gears won’t change until you do start pedaling, and when you do, you ‘ll hear some very disconcerting noises. You also don’t want to shift the gears while standing still.
