34T 104BCD Ergo Oval Ring

This 34-tooth chainring uses a certified oval profile and is built exclusively for cranksets with 104mm BCD. Suitable for MTB, BMX, and gravel-compatible cranks, it mounts directly using standard M5 bolts. Manufactured from high-purity aluminium alloy, it achieves exceptional strength-to-weight ratio — with dimensional stability ensured by consistent wall thickness and CNC-machined tooth profiles. The oval form factor enhances pedalling economy by aligning chainring radius changes with physiological torque curves: greater effective radius during active push phases boosts acceleration and hill-climbing response; reduced radius during passive phases lowers resistance and aids recovery. Users report improved cadence fluidity and reduced post-ride soreness. Dual-direction tooth shaping — integrating forward-facing (drive-side) and backward-facing (return-side) teeth — ensures constant chain engagement regardless of pedal direction or terrain-induced vibration. This makes it uniquely suited to technical trail riding and urban cycling where chain security cannot be compromised. Targeted at riders upgrading from stock round rings on 1x AM/XC platforms or seeking ergonomic refinements on rigid or hardtail MTBs — this ring delivers tangible functional benefits without altering existing component compatibility.
