What is the smallest chainring for 130 BCD?

What is the smallest chainring for 130 BCD?

38 is the smallest ring supported for 130mm BC.

What does 130mm BCD mean?

Bolt Circle Diameter What is BCD? BCD stands for Bolt Circle Diameter. It is the distance from side to side of a circle that goes directly through each bolt hole in a crankset. When you see a measurement like 110 or 130 BCD, that means that diameter is 110 or 130 millimeters, respectively.

How do narrow wide chainrings work?

The sole purpose of the narrow wide chainring is chain retention. The narrow wide tooth pattern keeps the chain from moving left to right and eventually popping off the chainring while riding. No one likes to drop their chain on the trail, especially in a race scenario where every second counts!

What is the largest chainring for 110 BCD?

52T is the maximum you can find for 110 BCD. Bigger chainrings would be too flexible for such a small BCD.

What is a compact chainring?

Compact chainset​ A compact chainset has a 50-tooth outer chainring and a 34-tooth inner chainring. This means that the gears are lower (easier to turn, but they’ll progress you a shorter distance per pedal revolution) than you get with a 53/39 chainset (above) with the same cassette.

What does a bigger chainring do?

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.

Are bigger chainrings more efficient?

Bigger chainrings and cassette cogs run more efficiently than smaller ones but extreme cross-chaining can cancel out those efficiency gains. Bigger chainrings and cassette cogs run more efficiently than smaller ones but extreme cross-chaining can cancel out those efficiency gains.

Do I really need narrow-wide chainring?

A narrow-wide ring is only necessary if you have a single chainring at the front and a rear derailleur. They won’t work at all if you have more than one chainring at the front, since you won’t be able to change gear.

What is the smallest chainring for 110 BCD?

33 tooth is the smallest size that will fit the 110 BCD….but they’re hard to find.
