What size chainring is best for climbing?
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.
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.
What does a larger chain ring do?
The larger chainring gives you bigger, harder to turn gears that move you further per pedal revolution – so it’s suitable for higher speeds – while the smaller chainring gives you gears that are easier to turn but move you a shorter distance per pedal revolution – so it’s suitable for lower speeds, including riding

Oval chainrings maximize the part of the stroke where power is produced and minimize resistance where it isn’t. As a direct consequence, Oval rings enhance a cyclist’s ability to spin with a smoother power delivery and feel much easier on legs while climbing. Meaning you will go faster and get less tired.
Are all chainrings compatible?
You can replace the chainrings on your crankset, but not all chainrings will fit all cranks. First, different cranksets may have a different number of arms or direct-mount interfaces (connecting the cranks to the chainrings), and they may be positioned differently.
