Readers ask: How To Adjust Shimano Gears On A Mountain Bike?

How do I adjust my bike shifts?

Here’s how to do it:

  1. Step 1: Shift into the smallest gear. I also like to drop my cable tension as low as possible.
  2. Step 2: Adjust the high limit screw, usually marked with an “H”.
  3. Step 3: Tension the cable properly.
  4. Step 4: Carefully shift up into the largest gear.
  5. Step 5: Fine adjustments.

What is the easiest gear on a bike?

The easiest (lowest) gear is when the chain is on the smallest ring in the front and the largest cog in the rear. The rest of the gears range between those two extremes. The bigger chainring is HARDER to pedal and the smaller chainring is EASIER to pedal. The ring(s) in the front are individually called chain rings.

Do you pedal while shifting gears?

You must be pedaling when you change gears. That’s because the chain has to be moving in order for the derailleurs to “derail” the chain from sprocket to sprocket. 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.

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.

How do you adjust gears?

Put the gear lever into top gear, turn the pedals and allow the chain to go onto the smallest cog on the cassette. If there is a cable adjuster on the gear lever body, or the derailleur body, screw it almost all the way in (clockwise).

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.

How tight should front derailleur cable be?

You need to pull it pretty tight before clamping it to the derailleur. Probably as tight as you can. Usually I find that’s still not tight enough, so I screw the barrel adjuster down all the way before putting the cable in and then open it up until the tension is correct.
