Delayed down shift

Sometimes when I go from 5 to 4 in the back, it takes a pretty long time to shift, it's really annoying Cuz sometimes it's at stops, and it won't fully shift. So when I go to start moving it shift while I'm starting and is really bad. My bike is like 2 months old

Downshift means going from a harder gear to the next easiest gear. You are trying to shift from one harder gear to the next easier gear which mean the chain has to move from the smaller cog to the next bigger cog. You are getting a delay there. Try turning the barrel adjuster counter-clockwise a little big, a quarter to half turn. That will put slightly more tension on the rear derailleur cable which then should hopefully allow the shifting to speed up a bit.

Also I'm confused by what you are talking about in regards to stopping and starting. Its best to downshift to your favorite takeoff gear before you come to a full shop. That way when you take off, you aren't trying to immediately shift while trying to pedal from a dead stop. That is hard on the gears since you are putting a lot more torque to try to take off in a harder gear.

Any other downshift is seamless but sometimes this one just doesn't catch, it's like I'm peddling like 4 revolutions and nothing. Sometimes I have to shift back up when I get back to stops because even the 5 or so Seconds I had given myself wasn't enough time and I have to start in a higher gear

One of the benefits of an IGH is it Downshifts after you have stopped.

you have to learn technique, to use the drive train you have . anticipate, read the terrain ahead.

try picking the back wheel off the ground and turn the pedals to finish a half completed derailleur gear shift.

So your saying it's normal to that every downshift takes a second but going from 5 to 4 I must learn special technique and prepare 15 seconds before hand so that I can successfully downshift for a stop.

Did you try adjusting the cable barrel adjuster like I suggested?

The first thing I'd do would be to clean and lube the rear derailleur cable. Start by shifting up to the biggest cog in the back. Then without turning the pedals, shift towards the smaller cogs. This should allow the cable to go slack. Check the cable guide under the bottom bracket for dirt, dried-up worms, Gatorade residue, etc. Clean the guide and the cable then lube it with some light oil. I like using a teflon-based lube.

Next go to the rear derailleur and gently pull out the cable housing from the chain stay holder. There should be a split in the holder to allow this. Slide the cable housing to expose the cable. Clean and lube the cable.

While your there, spray some lube into the pivot pins on the rear derailleur.

Put everything back together and shift up towards the largest cog again.

IMPORTANT: Make sure that the cable is in properly the guide under the bottom bracket.

You assume you are being clear in your description,

but its not,


Its just a typewrite I cannot see the Mech working .

maybe you bent the derailleur hanger when the bike fell over. Have It/Him checked in A Bike Shop.

You assume that your posts are helpful when in fact they are not

I'm almost positive you were the same condescending price who was bashing me in a previous thread because it wasn't written up to your standards.

You didn't mention 6 or 7 or........., so I'll assume it's 5 speed.
Modern 5 speeds tend to be on the bottom end bikes and frequently will never shift both ways properly.
You get it to work upshifting and it's crappy downshifting or the reverse. Sometimes both ways.
