Should you run larger chainrings?

Just how much more efficient are bigger rings and can they benefit non-professionals?

To give a little context, for a few years now, SRAM has offered 12-speed road groupsets which include a diminutive 10-tooth smallest sprocket. This allowed smaller chainrings to be used while still providing similarly high gears compared to standard setups.

However, some pro teams were reticent to move onto the smaller rings and stuck steadfastly to their traditional 53/39 cranksets – most notably Trek Segafredo. Responding to this, SRAM recently released three new cranksets, with big rings that span from 52 teeth right up to 56.
