The Renthal 1XR chainring tooth profiling ensures the highest level of chain retention, in all conditions. Alternating 1.8/3.5mm width teeth interlock with the chain for ultimate security, with no loss of efficiency.
The reduced frontal profile of the 3.5mm wide teeth increases mud clearance for the inner chain plates and extends longevity. Durability of the hard wearing 7075 T6 aluminium construction is maximised with a hard anodised surface treatment and mud evacuation grooves in the tooth bed.
Renthal 1XR : Designed to ride faster, jump further and last longer
Wide Tooth Profiling
The sculpted profile of the wide tooth adds significant clearance for the chain inner plates. This vastly increases the longevity and improves chain retention in muddy conditions.
Ultimate Chain Retention
Alternating 1.8 / 3.5mm teeth interlock, in sequence, with the inner and outer links of 9, 10 or 11 speed chain, to give the highest levels of chain retention and efficiency.
Mud Grooves in Tooth Bed
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.
Full CNC Construction
The 1XR is fully CNC machined from 7075 T6 aluminium alloy. CNC machining allows accurate tooth face profiling and the maximum width contact area, for greater longevity.
A CAD I-Beam cross section is utilised to give the maximum strength and stiffness, with the lowest possible weight.
High Quality Finish
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.
