## What is the smallest chainring for 130 BCD?

38 tooth

What is the smallest chainring set I can put on a 130BCD crank? 38 tooth. The smallest inner chainring I’ve been able to find is a 38 tooth. Anything smaller and you, the chainring teeth will run into the chainring bolts.

## What is the smallest chainring?

The award for the smallest chainring on a road crankset goes to Middleburn with their 94/58 BCD “Incy” chainring spider (removable). The “Incy” spider offers a small front chainring as low as 20 teeth!

**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 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 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.

**Will a smaller chainring help with climbing?**

If you need easier gearing, just swap to a smaller chainring. This is good for riders who struggle with climbing, regularly ride steep terrain, or carry extra weight with bike bags. On a mountain bike, the small change of swapping from a 32t to a 30t chainring gives you gearing that is 6.7% easier.

#### Is bigger or smaller chainring faster?

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

#### What is the benefit of a compact crankset?

The biggest benefit of a compact crankset is the ability for the system to afford lower gears for climbing, while still offering the required gearing for high speed riding in the flatlands. This is the number one benefit and is reputedly the main reason behind cyclists choosing to ride compact cranksets.
