A narrow-wide chainring for road, gravel and cyclocross that promises precise chain retention and significant weight savings. Lighter, stiffer gearing helps riders climb faster and feel more responsive under load. How well does YBEKI Chainring balance race-ready lightness with everyday durability?
⚡ At a Glance
- • Weight & Stiffness: Major weight reduction versus steel combined with high lateral stiffness for efficient power transfer
- • Best for: Road, gravel and cyclocross riders seeking lightweight single-ring setups on 8-12 speed drivetrains
- • Not ideal for: Riders who require multi-chainring setups or specific shifting ramp compatibility
7075-T6 aluminium, 5-axis CNC machined to ±0.01mm tooth tolerance and 130BCD, made for 8-12 speed Shimano 105/Ultegra and SRAM Force drivetrains. Military-grade hard anodisation, alternating narrow-wide teeth and Dynamic Chamfer Technology reduce wear and chain drops.
Fewer chain drops – with alternating narrow-wide tooth profile and Dynamic Chamfer Technology
Alternating narrow (6.8mm) and wide (7.3mm) teeth match 8-11 speed chain pitches, while Dynamic Chamfer Technology improves chain engagement speed. Factory testing cites a 92% reduction in chain drops on rough terrain.
More confidence on rough descents and single-ring runs, with far fewer interruptions from dropped chains.
Efficient power transfer – with 7075-T6 aluminium and asymmetric reinforcement ribs
Aerospace-grade 7075-T6 aluminium is CNC machined to ±0.01mm, while asymmetric ribs deliver a measured lateral stiffness of 155Nm/deg and up to 98.7% power transfer efficiency.
Hard efforts and sprints feel crisp, turning pedal inputs into speed with minimal flex and energy loss.
Durable low-friction teeth – with mirror polishing and military-grade anodisation
Mirror-polished teeth achieve an ultra-low friction coefficient (0.09μ) and hard anodisation reaches HV800 surface hardness for improved wear resistance and corrosion protection.
Teeth stay smooth through wet and muddy rides, while surface treatment extends service life and keeps performance consistent.
✨ The 4 Key Reasons for YBEKI Chainring
