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 aluminium construction is maximised with a hard anodised 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 construktion
• Precision CNC machined to extremely tight tolerances
• High strength 7075-T6 aluminum alloy provides excellent durability
• Hard anodised surface coating for increased longevity
• 11 speed compatible
• 104 mm bolt circle diameter
• Weight: 36 g (30t version)

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