A chainring is a chainring right? Well sort of, but e.thirteen rings do offer something a little different to the competition. You see, instead of the usual 34, 36 and 38 tooth increments, the e.thirteen rings are available in odd numbers too (from 32t to 40t in one tooth increments). So as more and more of us run a single ring and chain device up front with a wide ratio cassette on the rear, it means you can really fine tune the gearing to suit your individual power and cadence, as some of us are ‘spinners’ and others of us are ‘grinders’. On top of this the e.thirteen rings are really light and well finished, confirming them as the ideal choice to dial in your ride.
