51. How to Install a Shimano HG or IG Chain
Removal and installation of a Shimano HG or IG chain pin.
In this tutorial, we will learn how to remove and install a connecting pin on a Shimano HG or IG chain. These type of chains always require a special replacement pin that has larger peens.
For this job you will need a Shimano compatible chain tool such as the Park CT-3, and a set of pliers for breaking the connecting pin after installation. You will also need a black Shimano replacement connecting pin for 6, 7 or 8 speed chains, or a silver pin for 9 speed super narrow chains.
The first step is to break your chain using a chain tool. If you have previously used a replacement connecting pin, do not disconnect on that pin. The replacement pins can only be used once. Break the chain on any previously unused pin. When you push the pin out, it may be difficult as it will widen the plate holes on its way through. The replacement pins have wider peens to make up the difference. Once removed, discard the old pin.
When installing a chain, always place the chain in the chain tool grooves furthest from the handle. See the tutorial titled "How to use a chain tool" for more detailed instructions.
Push the replacement pin in with the narrowed end first, then tighten until the narrow end is fully exposed on the other side. The wide end should protrude equally on both sides of the chain.
Now using your pliers, break off the narrow end of the pin. If the link feels stiff, place the chain on the inner grooves of the chain tool closest to the handle, and tighten it just a bit until the link rotates smoothly. For more tips on loosening stiff links, see our tutorial titled "How to loosen a stiff chain link".

Hi, this is my first post to the forum! I have an old Focus MTB, bought it just recently second hand and I am also new to biking so please excuse me for being naive.
The problem started after the first miles with the bicycle, hearing a noise from the back. It was getting louder and louder very quickly and now, when I am pedaling everything is normal but when I stop and keep the pedals still, while on the road, the chain turns really loose and even goes out of the ring. This happens all the time. Tried with some lube and also tried to see if there is an obvious problem with the chain b... Read more >>
Removing SOLEUS freewheel DIY without a remover, garage style tip for everyone...
I was trying to clean and grease my wheel bearings, looks like removing the free wheel is a must do type of thing on my bike. I found that a regular old school Chevy GM craiger style lug nut fit in there perfectly. I think its ... Read more >>
I have. 2015 Defy 5. It has a FSA Tempo, 34/50 crankset.
Is this compatible with the Shimano 5800 group set? I currently have this setup with my Defy 5. She shifts a little rough on the front dérailleur. I guess what I am wondering is if I need to upgrade the crankset to the 5800? The bike came with a Claris setup. What I do not know is if there is an issue with 'spacing'. My current setup has 5800 shifters, FD, RD, chain and cassette (16 tooth removed and no indexing issues).... Read more >>
I'm new to bike repair. I use an old bike to ride around my neighborhood with my kids so I'm not a serious rider. My bike has a Shimano FH-RM40 7-speed hub and cassette. It's been difficult finding direct replacements for those components. Is there anything else that will fit without having to change out the entire wheel? I don't mind upgrading if the cost isn't too high. What are my options?
Thanks...... Read more >>
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 >>
