Changed shifters and chain isn’t in same spot

Asked by: Tony Rogers

Do shifters and derailleurs have to match?

As a general rule of thumb, it’s best not to mix and match drivetrain components from different brands. While things such as cranks, chains and cassettes are mostly inter-compatible between brands, generally speaking, shifters and derailleurs aren’t.

Why does my chain come off when I change gear?

If your chain regularly comes off the inside of your chainset, it could be that the L screw needs adjusting. Put the chain on the small chainring and the largest sprocket at the back. The inner plate of the front derailleur cage should nearly but not quite touch the chain; we’re talking about a gap of 1-2mm.

How do you align bike shifters?

Quote from video: So we want the angle of the shifter. To follow the drop on the bar. So it should be nice and straight it's a good starting point. We have a positioned where we'd like it.

Does chain line affect shifting?

Chainline mismatch can cause the chain to rub against the side of an outer, larger chainring when engaged with a smaller one, and can cause problems with shifting, especially with the front derailer.

Can you mix shifter and derailleur?

In many instances, it is possible to mix different levels of shifters and derailleurs from the same brand (e.g. Dura-Ace/Ultegra/105; Red/Force/Rival; Super Record/Record/Chorus), however it’s not safe to assume that this will always be the case.

Can you replace shifters on a bike?

There are several types of shifters, but they all operate on this same principle. Although reasonably durable, shifters do eventually wear out. If you’re comfortable with basic hand tools and mechanical concepts, then replacing a bicycle gear’s shifters is not at all that difficult.

Should chain be touching derailleur?

The cage should be positioned very close (1mm to 2mm) to the chain on the inner (bike) side, without causing it to rub. If it’s rubbing, loosen the L screw in very small increments (quarter turns or less) by turning it counterclockwise until the chain no longer rubs while pedaling.

What happens if your chain is too loose?

The major symptoms of a loose chain include chain teeth skipping over the sprockets, uneven transmission of power to the wheel leading to jerky wheel movements, chain lash and the chain slapping the swindle arm, and in the final case, chain coming off the sprocket.

Why do I jerk when changing gears?

Rough jerking when shifting



This is usually caused by troubles with the vacuum, transmission fluid or a faulty sensor. The vacuum modulator valve helps older vehicles determine when to shift gears.

How do you align Shimano gears?

Quote from video: The derailleur down into the small cog. Once we do that we're going to turn the barrel adjuster all the way in so that we have room to adjust it. After adjusting the cable position at the anchor.

How do you fix a misaligned derailleur?

Quote from video: So if you have an l-shaped allen key that's great you can insert that into the mounting bolt of your derailleur. And you can use that as a lineman gauge.

How tight should bike shifters be?

On a road bike you’ll want them fairly tight to be able to ride on the hoods without the brake levers turning away or moving downward on the bar.

Which gear combination is best for cycle?

For regular terrain on a flat road, the middle gear is ideal. You can shift to the middle gear if you need strength, but not enough to ride on undulating roads. Combine the middle chainring with a triple rear cog to bike ride smoothly on a flat road. For beginners in biking, it is best to keep the bike in middle gear.

How do you align a derailleur?

Quote from video: We then rotate the tool hundred and eighty degrees. If this gap is larger than three millimeters. We know our hanger needs a bit of straightening. So we bend and we measure our distance to the rim.

What gear combination is best for going uphill?

Low Gear = Easy = Good for Climbing: The “low” gear on your bike is the smallest chain ring in the front and the largest cog on your cassette (rear gears). In this position, the pedaling will be the easiest and you’ll be able to pedal uphill with the smallest amount of resistance.

Can I use Shimano derailleur with SRAM shifters?

The SRAM rear derailleur (mech) will not work with a Shimano shifter as is; the cable pull and shift activation ratios are not the same between the two systems.

Can I mix SRAM shifter with Shimano derailleur?

Condensed Answer: In general, it’s possible to combine a Shimano front derailleur with a SRAM shifter because both brands use extremely close cable pull ratios for the front mech.

Can I use 11 speed derailleur with 10 speed shifter?

Can An 11-speed Derailleur Work With a 10-speed Cassette and Shifter? Condensed Answer: Shimano’s 11-speed derailleurs have a different rear shift ratio than 10-speed derailleurs and are therefore not compatible with 10-speed indexed shifters.

Can you mix and match Shimano?

You should have no problem mixing and matching these components. As long as everything is either Shimano 9speed or Shimano 10speed, you’re fine.

Can you cross chain on Shimano?

This uneven load causes extra friction which increases the wear on the chain and longer term leads to less than optimum gear shifting. For these reasons Shimano recommends avoiding extreme gear positions. Shimano says you should avoid running the chain in this big-big combination (above).

Is Shimano Chinese or Japanese?

Japanese

(株式会社シマノ, Kabushiki-gaisha Shimano), originally Shimano Iron Works (島野鐵工所) and later Shimano Industries, Inc. (島野工業株式会社), is a Japanese multinational manufacturing company for cycling components, fishing tackles and rowing equipment, who also produced golf supplies until 2005 and snowboarding gear until 2008.
