Mtb Ergal Chainring | Narrow Wide |1x 96bcd | 36t Alternating Teeth Interlock - Shimano Pattern

"The Renthal 1XR chainring tooth profiling ensures the highest level of chain retention, in all conditions. Alternating width teeth interlock with the chain for ultimate security, with no loss of efficiency. Intricate tooth profiling increases mud clearance and extends longevity. The Renthal 1XR offers ultimate chain retention performance and market leading durability. ""Alternating 1.8 / 3.5mm teeth interlock, in sequence, with the inner and outer links of 9, 10, 11 or 12 speed chain, to give the highest levels of chain retention and efficiency. The tall, square tooth profile ensures the very high level of chain retention isn't reduced as the tooth face wears."Mud grooves, located in each tooth bed combined with ample clearance below the outer chain plates, allows dirt and mud to be purged clear of the drivetrain, improving performance and durability.A CAD I-Beam cross section is utilised to give the maximum strength and stiffness, with the lowest possible weight.The 1XR is fully CNC machined from 7075 T6 aluminium alloy. Utilising CNC machining production allows accurate tooth face profiling and the maximum width contact area with the chain rollers, for greater longevity.After CNC machining, the 1XR chainring is hard anodised to give an incredibly durable surface finish. The chainring is further enhanced with the application of a 3-D graphic in a CNC machined recess.
