2 Answers. To quote Sheldon Brown: “If the chain is too short, it will be at risk for jamming and possibly ruining the rear derailer if you accidentally shift into the large-large combination. … But you really should get the chain to be of the right length before riding.
What happens if my bike chain is too short?
If the chain is too short, this shift is difficult to make and the derailleur cage is stretched out and almost parallel to the chainstay. If the chain is really short, then you might not even be able to shift into the largest cog. … Before you remove the chain, make sure it’s on the small chainring and smallest cog.
Should I shorten bike chain?
Why Shorten a Bike Chain? All bikes come with a recommended bike chain length. It’s important to stick to this length if you want to ride comfortably and preserve the life of the rear derailleur. It’s the bike chain that does the work of getting the tires in rotation so that your bike can get in motion.
How long should my bike chain be?
Replacing your chain regularly can prolong the life of your drivetrain. Most mechanics agree that you should replace your chain about every 2,000 to 3,000 miles, depending on your riding style. Many Tour De France riders wear out two or even three chains on their primary bike over the course of the three-week race.
Can you lengthen a bike chain?
Yes, you can add links to a bike chain , but you need to be careful that you have the right tools ( Chain Tool/Master Link Pliers) and correct methods. … All bikes should be able to make this shift, and the derailleur should not appear stretched too tight.
Does chain length affect speed?
Registered. Sprocket and gear size affect performance (speed/torque)… The length of the chain will only effect your wheel base…
How do I know if my bike chain is too long?
Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward. If it moves just a little, then you’re good. If it moves a lot, then you’ve got too much chain.
How many links do I need in my bike chain?
Bicycle drive chain length
A new bicycle chain usually comes with 116 links. This is long enough for the biggest chainrings and for most distances of rear wheel from front chainrings. So for optimal length a new chain is usually shortened from the 116 links that come in the box.
How do I know what bike chain to buy?
Begin by counting the number of teeth on the largest front sprocket and largest rear. These numbers are often printed right on the sprockets and cogs. Next, measure the distance between the middle of the crank bolt to the rear axle. This is also the chain stay length.
How do I know what speed my bike is?
The only way to know what’s on your bicycle is by determining the number of teeth on the largest gear on your rear wheel. This is typically shown on the cassette’s packaging. For example, a road style 8 speed cassette might be marked as: 8 speed – 11-28t.
Are bike chains universal?
All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.
Can you put 2 master links on a chain?
A master link is just as strong as any other link on the chain. There’s no reason you can’t use a couple of them.
Can you reuse bike chain pins?
Yes you can reuse a freaking HG40 pin. As someone said, when you break the chain don’t push the pin all the way out, just enough to separate the link. I’ve even reused 10 speed chain pins. In 28 years I’ve never had a chain snap on me.
