NON-ROUND CHAINRINGS designed to increase leverage in the most powerful phase of the pedal stroke and then back it off in the weakest part aren’t new, but this absoluteBLACK ring has made a big impression on some of our testers.
What started years ago with the timeless Widget has now become either a craze or passion. Mountain bikers everywhere are ditching their excess chain rings, shifters and front derailleurs. Reasons to do so abound: lower weight, greater simplicity, lower running costs, wider range cassettes and of course fashion.
THE MARKET IS now flooded with single chainrings that ape the chain-hugging narrow/wide tooth profile debuted on SRAM's X-SYNC ring, and for good reason - the design works brilliantly.
