20. How to Loosen a Stiff Chain Link
Stiff chain links cause noise, shifting problems, and even injury. Watch how to fix it by hand!
A stiff chain link can cause problems with your shifting, and can even cause injury if it slips while you're pedaling. Here's how to easily diagnose and fix the problem.
You'll know you have a stiff link if your chain skips every 3 or 4 rotations. If you have several stiff links you'll feel it skip even more often. To find the link, shift down to your smallest rear sprocket and then run the chain backwards through the derailleur by rotating your crank. Keep a close eye on your chain as it rolls over the lower derailleur pulley. When the stiff link passes through you'll see it jump over the pulley. This means the inner and outer plates of one of your chain links are squished together too tight at the pin.
To fix this by hand, simply work the plates loose by twisting the chain up and down the same way it was meant to. Then point the stiff link upward and firmly grab the closest connecting points on either side. Now twist the chain side to side, the way it was not supposed to bend. If all goes well, your stiff link should now be loosened and you can continue riding.
If this method doesn't work, and the link is still stiff, you'll have to use a chain tool to fix it. Place the stiff link into the chain tool, on the slots closest to the turning handle. Now thread the chain tool's pin gently against the chain pin about 1/8th of a turn, or just enough to slightly loosen the chain plates. That should loosen it enough.
If you still have problems, the chain may actually be bent and need replacing.
I need some advice. I bought a used, "as-is", 2015 Fuji Nevada 1.9 Mountain Bike with 3 x 7 gears from a LBS. I ride it a lot, 10-20 miles 3-7 times a week. The spin-on freewheel was a factory issued SunRun 14-34 and it literally fell apart in 2 months. (Yes, SunRun, not Sunrace) I purchased and replaced the old SunRun with a new SunRun 14-34 and after 3 weeks it is wobbling. I had another LBS check it out, they are scratching their heads. I am wanting a better quality freewheel than the Fuji factory issue of the P.O.S. SunRun Brand. The Shimano Tourney 14-34 makes sense but is there a better ... Read more >>
The chain on my exercise bike became too long over time and started "slipping". So I took the chain off and took off one section (2 links - a female and male) and replaced the pin to complete the repair. Now the chain is too short to put back on the bike - what I needed was a way to make it one link shorter (not one section=2 links). Is there now a way to make the chain just one link longer? Some sort of male to female single extension link? Thanks.... Read more >>
Complete carbon fiber (frame) road bike less than one year old - 105 10 speed. Built it myself and it has been fantastic up to now. About a month ago I started getting a loud rattling noise everytime a rode over slightly rough ground (chip and seal). on smooth road it is silent. It is obviously coming from the rear part of the drive. I always ride on the big ring on the 4th cog from the top - flatland. Here's what I have checked : Chain is a good length but I have tried two links shorter and two links longer. Tried a brand new chain. checked that all bolts are tight, pulleys, ... Read more >>

The chain comes off my rear small sprocket on back peddling. The bike rides good other wise.
I have noticed other riders on the side of the road with the same problem. Without a wheel wrench it is quite hard to free up and put back onto the gear cluster. What causes this malfunction?... Read more >>
Being new to this hobby I ran across the 12" rule for chain wear. You pull the chain tight, right on the bike, measure 12 links, the distance between 25 pins, and if it measures 12" the chain is like new. If it measures 12 1/8" you throw the chain away and replace it.
Something new to check out now. i imagine a worn chain causes shifting problems as well as drive train inefficiency. Do others here you use this method for determining chain wear??... Read more >>
I am asking this one for my dad (78.5 yrs old). He just got a bike on craigslist (Marin Redwood), comfort style.
He likes it, but wishes that it had lower crank gearing. According to the Marin website, I see that it has a "Crankset: Suntour XCT light 48/38/28".
My dad says that he thinks the chainrings are riveted on, but his eyesight isn't the greatest, and I have not had a chance to go there and look for myself.
Do you guys know whether the chainrings are replaceable on this "XCT light" crankset? I can't find any specific info to ... Read more >>

First of all I have been trying to research this bike and have come up empty.
What I do know, it has a belt vs chain and it looks a little dry.
I don't even know where to begin to find a replacement for it because I can't find it anywhere on the internet.

I am buying a new bike, it has a Shimano FC-5703 triple ring crankset, 50X39X30T, bcd 130mm.
I am a casual rider, and really want some type of chainguard on here so that I can ride in jeans without need for a leg wrap to keep my pants leg out of the chainrings.
I do not know what the difference is between a "bash guard" and a "chainring guard / "chain guard".
Regardless, what is the best way to accomplish some type of chainguard on here? What will I need? I can find chain guards sold on ebay made by Driveline, but is that the correct ... Read more >>
I have a 2012 Trek 7.5 Fx Hybrid bike that I need to replace the Freehub body on the rear wheel. There are no identifying marks on this hub anywhere. The cassette that is mounted on the Freehub body is a CS-HG61-9. The gears on the cassette is 11-34 and its a 9 speed. Is there anyway to exactly identify what freebody hub this is so I can get an exact replacement?... Read more >>
Well, hello everyone this is my first post.
I have been trying to renovate an old road bike a British hercules. The thing is that the bike has old components and I have trouble finding other ones. I want to keep the front chainring 48t but remove the internal hub that my gramp was using. Instead i decided to buy a nice wheel with a 9 cassette and the suitable deraileur. Well my main problem is...Will this fit with the 48t chainring? Is the deraileur going to be ok with the claw type hanger (the bike has no built-in hanger)? In copenhagen where I live we have no steep hills, every... Read more >>

I got a Bell brand chain from walmart for my other bike and the quick link is so annoying to put back together when I need to take it off for some cleaning. Well, I try and hold the derailleur and put the chain back together but I suffer from panic attacks from time to time and I just get so annoyed with having to hold the derailleur and putting the link back together at the same time. Any tips to help me do it better without getting frustrated or annoyed?... Read more >>
So my bike kind of broke and I adjusted some things to fix it, but then a new problem arose.
The thing that broke and bent badly was the metal that held the two cogs in the back wheel of the bike ( the gear shifting thing) so I bent it back into shape and screwed it back on but whenever I pedal the bike the chains starts going into its cycle but in a few seconds the chain slips off the bottom cog in the gear shift and the chain slowly slips off everything else. Is there anyway I can fix this?[/align]... Read more >>
