Renthal is saving their big guns for the Taipai show next week but they were happy to show off two new 1 x 11 chain ring options: one for the new Shimano XT and one for SRAM's 94 BCD (Shimano on the left, SRAM on the right). Standard wide-narrow chain profile to keep the chain behaving properly., hard anodyzied 7075 alloy, I-beam rigidity, and a mud channel to shed trail debris. All for $60. 30T-38T options.
