The Pilo C97 38T Narrow Wide Chainring is a premium upgrade for riders seeking superior performance, durability and smooth operation. Designed for 104BCD cranksets, it delivers perfect chain engagement and retention for both trail and E-bike use.
CNC-Machined from Aircraft-Grade Aluminum: Each C97 chainring is precisely CNC-milled from 7075 T7351 aircraft-grade aluminum sourced from Constellium, Switzerland. This material ensures exceptional stiffness, strength and low weight while maintaining excellent wear resistance over long-term use.
Engineered Tooth Profile for Quiet, Efficient Operation: Pilo’s advanced narrow-wide tooth geometry, developed in line with DIN8196 (ISO) standards, guarantees reliable chain control. The design reduces noise, minimizes friction and prevents chain drops, offering a smooth and efficient pedaling experience in any condition.
Wide Drivetrain Compatibility: Compatible with 104BCD cranksets, the C97 chainring works seamlessly with all 10, 11 and 12-speed chains from SRAM and KMC, including Shimano Hyperglide+ x12. With a 0mm offset and an outer diameter of 161mm, it maintains perfect alignment and chainline across setups.
Each ring is E-bike proven and manufactured in Pilo’s ISO 9001:2015 certified facility, ensuring outstanding quality, precision and reliability for every ride..
