Do MTB chains have O-rings?


Most modern motorcycle are sealed with O-rings (or X-rings / some other fancy rubbery ring) to keep grease inside the pins

; it stands to reason that non-sealed chains (found on small-capacity bikes) need lubricating, but is motorcycle lube necessary on bigger bikes, or is it just a scam to make us spend £ …

What is the difference between an O-ring chain and a regular chain?

The O-rings encircle the pin bushings, and rest between the outer link and inner link plates. This seals chain grease in the pins and rollers, maintaining better lubrication for longer. Because of this,

O-ring chains have a reputation of lasting anywhere from 1.5 – 2 times longer than standard, non-O-ring chains

.

How long do O-ring chains last?

But chains wear out over time and need replacing. So, how often should a motorcycle chain be replaced? In general, a properly maintained motorcycle can last

20,000 to 30,000 miles

, sometimes more. But, some last as little as 5,000 to 10,000 miles.

How do I choose an O-ring?

The size of an O-ring can be determined by

measuring the diameters and the width of the cross-section

. The measurement you will need to include are the internal diameter (ID), outside diameter (OD), and the cross-section width (CS).

Does an O-ring chain need lube?

Reasons include, to reduce rust and corrosion, to provide protection at extreme pressure points between the chain rollers and the sprocket teeth and

to lube between the O-rings and chains plates

. We like to use a good lube after washing an O-ring chain as it displaces moisture and fights corrosion.

Do you need to lube a new bicycle chain?


It is best not to apply any sort of lube to a new chain until it is clearly needed

, because any wet lube you can apply will dilute the factory lube. I use dry lube even through winter. Needs lubing before every ride but worth it for a clean chain.

What is O-ring in bike?

The O-Rings are

used to keep grease and lube inside the chain

(between all the moving parts). The non O- Ring types date back to the beginning of time and are still used today.

Are O-ring chains quieter?


The O-ring chain will typically be quieter when riding unless your sprockets are worn and/or the chain is out of adjustment

.

When did O-ring chain come out?

The solution came in

1971

with the development of the O-ring chain. In short, this innovation added a rubber insert between the inner and outer link plates to act as seals to keep dust and debris out, retain lubrication, and reduce metal on metal friction.

Do O-ring chains Rob power?


O-ring chains eat horse power

. Over sized chains eat horse power. When you only have 10 – 12 HP to start with, you can't afford to loose any. But if you have a 50 HP bike, loosing half a HP to an O-ring chain isn't noticable.

What is Z ring chain?

Patented since 2003

The special Z-Ring section

provides enhanced chain flexibility

. The conical section enhances the assembling on the bushing. The lubricant trapped between the plates and the lobes of the Z-Ring keeps the ring lubricated and increases its life.

What is a 420 chain?



All PEER roller chains incorporate solid rollers enhancing rotation on the

.

bushing while reducing impact loads on the sprocket tooth during operation

. – All chain components are heat treated to achieve maximum strength. and greater wear resistance.

Can Vaseline be used to lubricate O-rings?

Can you put a new chain on old sprockets?


When a sprocket is really, really badly worn, putting a new chain on it can cause problems

. But in most cases, even if the sprocket is “too” worn, a new chain will improve things at least a little. The chain may wear a hair more quickly, but not enough to notice.

How often should you change your bike chain?

It might be necessary to replace a chain that often if the bike is frequently ridden on wet or gritty roads. But chains can usually go

2,000 to 3,000 miles

or even longer before there's enough wear to relegate them to the trash bin, if they are well maintained.

How do I know what size O-ring to buy?

The best way to size an o-ring is by

measuring the CS (cross-section) and ID (inside diameter)

. For measuring the cross-section, it is best to use a caliper, a.k.a. micrometer. If you don't have one available, various other sizing tools can be used to get a close estimate.

What size is O-ring?

Inside diameter (inches) Inside diameter (mm) Alphabetical sizes (Australia, UK, etc) 0.674′′ 17.1 mm N 0.682′′ 17.3 mm N 1/2 0.69′′ 17.5 mm O
0.698′′


17.7 mm


O 1/2

Are there different types of O rings?

Some of the common types of O-ring materials include

PTFE, Nitrile (Buna), Neoprene, EPDM Rubber and Fluorocarbon (Viton)

. Silicone and Kalrez® O-ring materials are also widely used, especially in high temperature applications.

How do you care for an O-ring chain?

Is WD-40 good for dirt bike chains?

WD-40 is primarily a degreaser—a solvent that removes contaminants from an object, which helps to protect it from rust and corrosion. So

it can effectively clean and degrease your bike chain, and is especially good at removing any debris, gunk, and rust that is attached to the links to help it get moving again

.

Can you use WD-40 on dirt bike chains?

What is this?

Yes, the almighty WD40 is still a common chemical that riders use on their bike chains

. While it is great for keeping a chain clean and rust-free, it is more of a penetrating solution than a lubricant.

How often should you degrease bike chain?

Chain Lube – Part & Parcel Of Cycling

A clean chain is as critical as a properly lubricated one. Ideally, chains should be thoroughly cleaned

after each and every ride

. Unfortunately not many of us have the time to do this, but even a quick wipe with an clean rag can make a huge difference.

Do Shimano chains come lubed?


The grease that comes on a Shimano chain is applied at the factory to the individual pieces before the chain is assembled

. The grease does a better job of reducing friction than aftermarket chain lubes and it lasts longer.

How often should I oil my road bike chain?

If you are a frequent rider, using your bike several times throughout the week, your bicycle will benefit from a regular cleaning and lubrication of the drive chain. Bicycle Tutor recommends cleaning and lubricating your bike's drive chain

at least once every month

to maintain optimal performance and protection.
