What is a 1/8 bike chain?
1/8″ (0.125″, 3.18 mm) chain is used on most single-speed bicycles, and bicycles with internal gearing. 3/32″ (0.094″, 2.30 mm) chain is used on derailer equipped bicycles that have more than 3 cogs at the rear. Even somewhat narrower chain, typically .
Is a smaller chainring better?
The size of a chainring (often expressed in terms of the amount of teeth on it, e.g. a 53t ring) plays a direct role in your bike’s gearing, with bigger rings meaning a higher (harder to push) gear and smaller rings a lower (easier to push) gear.
What is the smallest chainring?
The AbsoluteBLACK 30t oval chainring is the smallest 104 BCD compatible chainring in the world, and it’s taken some clever engineering to make it happen.
Are 8 and 9 speed chains the same?
7, 8, and 9 speed chains have the same inner width, but 9 speed chains have thinner outer plates for a thinner overall chain. So while a 9 speed chain works fine on a 7 or 8 speed drivetrain, it will be a weaker chain that tends to “stretch” faster.
What size is 8 speed chain?
7.1 mm wide 8 speed chain will fit all the other systems (5, 6 and 7 speed ones). Shimano, SRAM and Campagnolo all use the same chain with 8 speeds.
How wide is a 8 speed chain?
3. Chain outer width
| TABLE 1 | |
|---|---|
| Number of sprockets (speeds) a chain is designed for | Chain outer width in mm |
| All 6 speed | 7.8 |
| All 7 speed | 7.3 |
| All 8 speed | 7.1 |
What is the best 1x chainring size?
If you have another drivetrain as a point of reference, this tool is great for finding the optimal 1x chainring for your needs. In general, stock 32t and 42t chainring sizes are good, but I think many riders will enjoy riding more with a smaller ring.
Is a 30t chainring good?
Mountain bike chainrings are available in smaller sizes all the way down to 26t, though I’d recommend most riders try a 30t or 28t first to experience how much easier it is to climb. For gravel bikes, I wouldn’t recommend going any smaller than 38t to maintain top-end speed on downhills.
Do I need a granny gear?
The granny gear is the smallest cog on the front crankset of your bike. I recommend picking gears for all occasions, that is, having gears low enough to go up the steepest climbs, and also having gears high enough so you don’t ‘spin out’ when the wind is on your side.
