A lot of thought and preparation must have gone into the making of this video. It contains a lot of very helpful clear guidance. I had to size a new chain from scratch and preferred to join the two ends at the bottom of where the chain goes rather than on the chain wheel.

Hey Ben! Is this tipe of masterlink at 1:00 directional? I have been using for years at the opossite side, luckily I never had any problems, but it does not mean that I did it correctly. Congratulations for all the videos about chains!! Love your channel an the brand!!

@lucianonarno1408 7 лет назад

Flor.e.Cultura yes, the close side of the master link should face the direction in which the chain is moving. If the open side is facing the direction of chain movement there is a very little chance that it could catch on something and pop off. I've never heard of this happening to anyone, so there is no problem if you put it backwards.

There should be relatively little chain slack in these chains. Keeping the chain pulled tight enough and connect it would be a good trick indeed.

One thing I am not sure about that is not entirely clear in this video , this ideal 12 mm amount of movement in the chain , is it 6mm up from where the chain sits and 6mm down to make 12mm alltogether ?, or 12mm up and 12 mm down , or just 12mm up from where the chain is sitting ?

@StadtradlerAt 7 лет назад

The chainring is on the left side of the bike (@ 9:37)? Looks as if you have your video mirrored..

Stadtradler some bmx's have a left side drivetrain if your right is your preferred "grind side" so you don't mess up your chairing, cog, and chain.

Can this be applied exactly as is to Internally geared hubs? A not sure why but I can't find a video on just chain replacement for IGHs.

For the purposes of this video, single-speed = one chainring in front, one sprocket in back. You’re in the right place.

@vetkosgarage6165 6 лет назад

What i need to do if i just wanna remove my single speed chain and put it back?

@parktool 6 лет назад

Depends if you have a master link or not. If you do just un do the link and remove the chain. If you do not you can push the pin 75% of the way out then pull the two sides of chain apart. To re install, the content from the video should have you covered.

@andreicristian1625 4 года назад

Is 17mm up-down movement too much movement for a conversion? I can't get any closer than this to the spec with an acceptable gear ratio.

@parktool 4 года назад

Get the bike up in the air to pedal and test it. Pedal and push on the chain at the point between front are rear sprockets. Purposefully try to disengage the chain, and shove it off the sprocket. If it stays on, you are good.

@lordgibbness 4 года назад

This guide was good. But some points from my experience recently doing this: 1. I couldn't add two additional links to the chain length when sizing, as it took away all adjustment to get the chain tensioned properly, and as the chain will slacken over time it would be too long for the frame adjusters. 2. You should fully grease the connecting link before installing. 3. The retaining clip should have the closed section facing forward in the direction of chain travel. Otherwise very useful guide... 👍

@lordgibbness 4 года назад

Regarding point one, I always size without the connecting link, so it will then lengthen by half an inch, when I add this later on...

@StephaneThiele Год назад

When my pedals are turning while pushing the bike, does this neccessarily mean that my chain tension is too tight? Greetings from Germany, great Video!

@parktool Год назад

Not necessarily. If the freehub is tight and not spinning well, it can also move the pedals.

@8Bitable 6 лет назад

I noticed that bike has a Surly Tuggnut. Never used them before, thinking about getting one ... Serious question: Do you use one on each side or only on the drive side?

@parktool 6 лет назад

I prefer a chain tensioner on one side. The majority of force that is applied is being applied to the driveside. So this is where you will benefit the most from the chain tensioner. The Tuggnut is fantastic BTW.

@8Bitable 6 лет назад

Thank you, this helps a TON!

PLEASE HELP ME I JUST NEED TO REMOVE HALF OF THE CHAIN LINK BUT THEN I CANNOT FIT THE LINK TO CONNECT IT!!! If i do not remove it the chain is to lose.... and if i remove the whole link the chain is to short and the wheel will be tightent at the verry beginning of the forward drop outs.... what can i do !!!???

@parktool 4 года назад

If you have a single speed there are often "half link connecting links that can resolve your issue. They come in eithere 3/32 or 1/8 depending on the chain that you have. Instead of 1" to remove or keep installed it is 1/2 inch. kmcchain.us/connector/415-ol/ Something like that but make sure the width is correct for your chain.

@tylermillard6824 3 года назад

Hi, so I picked up a Schwinn two sprocket off the road recently. All it needed was some inner tubes and a little maintenance. But when I ride it hard and/or break hard, the chain slips off the rear sprocket, even though it’s plenty tight. Any suggestions? I’m guessing maybe the rear sprocket is just old and worn down a bit and needs to be replaced

@parktool 3 года назад

That could be or possibly you have a stiff link in your chain. Interesting problem.

@tylermillard6824 3 года назад

I thoroughly applied WD-40, twice. Could it still have a stiff link?

@parktool 3 года назад

It could. A stiff link may not be a lubrication issue but sometimes a link of the chain has been bent. But this is more common on bikes with more than one gear. I guess i'm not super familiar with what you refer to as a two sprocket.

@parktool 3 года назад

Also make sure to use another lubricant over the WD-40 (unless a chain oil product from WD-40) WD-40 proper is not a lubricant and acts as more of a solvent to break things up and leave a very thin residue to keep things from rusting.

@vandieselcuuuz 4 года назад

What if my wheel is always coming loose does that mean something is bent on the frame ?

@parktool 4 года назад

Try lubricating the threads of the axle. That will allow it to get up to torque. Another reason that can happen is if the drop outs are painted and not giving the lock nut or the outer nut enough purchase to hold the wheel. Scuffing up the dropout can help as well.
