How do I know what bike chain I need?
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.
What number is bicycle chain?
The chain in use on modern bicycles has a 1⁄2 inch (12.7 mm) pitch, which is the distance from one pin center to another, ANSI standard # 40, where the 4 in “#40” indicates the pitch of the chain in eighths of an inch; and is standard 606 (metric) #8, where the 8 indicates the pitch in sixteenths of an inch.
Are 7 and 8 speed chains the same?
Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system.
How do I know my chain size?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
What is the difference between bicycle chains?
Chains can vary in side plate shape, sizing, and height. Differences can cause variations in shifting performance between brands and models. Additionally, chains will vary in the quality of steel used. Better chains that are more durable and longer lasting tend to have harder rivets.
How often should I change my bike chain?
The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4
Are all bicycle chains the same size?
Are all bicycle chains the same size? No, all bicycle chains are not the same size. Size varies on the bike’s numbers of sprockets, speeds, the distance between the front chainring and rear cogs, and the number of teeth on them.
Can I replace a 7 speed freewheel with an 8 speed?
You can change to 8 speed, but a normal rear wheel for roadbikes will not fit directly into the frame because it’s 130 mm wide. Depends on the stiffness of the rear frame if it can be pushed together safely to 130 mm.
Will a 9 speed chain fit 8 speed?
9 speed chain on an 8 speed cassette is just fine; it’s the wider 8 speed which won’t fit the sprocket spacing on a 9 speed cassette.
Are KMC chains better than Shimano?
The difference between the Shimano chain and the KMC is marginal; your choice will always come to personal preference. Despite the inconvenience of adjusting the chain, the Shimano runs a lot smoother and will provide you with long-lasting use.
What is the difference between.325 and 3/8 chain?
The three-eighths chain is a beefier saw and better suited to one that has more horsepower. It has larger teeth and a heavier duty chain, so it requires more horsepower to operate correctly. 325-inch chain for those saws between 40 and 60 cc.
How do I know my roller chain size?
Roller Chain Identification Most roller chain has the size stamped right into the side plates. You may see something like “40”, “C2080H” or “10B” stamped in, which the industry number that represents the chain size. Old chains will most likely need to be cleaned in order to see the size.
