The Renthal 1XR chainring tooth profiling ensures the highest level of chain retention, in all conditions. Alternating 1.8 and 3.5 mm width teeth interlock with the chain for ultimate security, with no loss of efficiency. The reduced frontal profile of the 3.5 mm wide teeth increases mud clearance for the inner chain plates and extends longevity. Durability of the hard wearing 7075 T6 aluminum construction is maximized with a hard anodized surface treatment and mud evacuation grooves in the tooth bed.

Details:

• Teeth with 1.8/3.5 narrow-wide profile
• Recesses in toothbed prevent extensive wear or chain derailment from mud
• Wider profile provides more chain clearance and extends longevity
• Stiff I-beam ring construction
• Precision CNC machined to extremely tight tolerances
• High strength 7075-T6 aluminum alloy provides excellent durability
• Hard anodized surface coating for increased longevity
• 11 speed compatible
• 94 mm bolt circle diameter
• Weight: 36 g (30t version)

Note: This is an exemplary illustration, number of teeth differs according to selection.
