PASS QUEST Shimano 110 BCD Hollow Round Narrow-Wide ChainringLightweight Construction. Enhanced Chain Retention. Precision Engineering.The PASS QUEST Shimano 110 BCD Hollow Round Narrow-Wide Chainring is precision CNC-machined from high-strength 7075-T651 aluminum alloy. Featuring an extended 8.5 mm tooth profile, a hollowed-out rear structure, and carefully chamfered edges, this chainring is designed to provide reliable chain retention and structural rigidity while reducing unnecessary weight. Key Features1. Precision CNC-Machined 7075-T651 Aluminum Alloy Manufactured from high-strength 7075-T651 aluminum alloy using precision CNC machining, this chainring combines structural strength with a lightweight construction. 2. Extended 8.5 mm Narrow-Wide Tooth Profile The extended tooth profile reaches deeper into the chain links, helping improve chain engagement and retention. With an optimized tooth height of 8.5 mm, the chainring is designed to help reduce chain drops during vibration and high-load pedaling. 3. Hollowed-Out Design and Chamfered Edges The reverse side features strategically machined cutouts to reduce unnecessary material while maintaining structural integrity. Carefully chamfered edges further optimize weight and create a clean, refined appearance. Shimano Crankset CompatibilityDifferent generations of Shimano 110 BCD cranksets feature different mounting arm shapes. Please check your crankset carefully before ordering.
Important: Please select the correct chainring version according to your exact crankset model. Not all Shimano 110 BCD cranksets are interchangeable. Technical Specifications

It is not suitable for 2x double-chainring systems and is not designed for use with a front derailleur. 2. Shimano 12-Speed Chain Compatibility When using a Shimano 12-speed chain, please replace the original Shimano quick link with a compatible KMC 12-speed quick link.

Looking for top-level professional cyclists
This is the new equipment for professional road bikers, track bikers, and time trial riders.
We designed and manufactured a 5mm thick narrow-wide chainring, increasing lateral stiffness and featuring a high bracket density. It weighs about the same as a carbon fiber chainring with the same number of teeth, but is much stiffer, making it suitable for riders with higher power output.
Our single-speed chainring has also been optimized and upgraded.
