CYSKY Chainring 36T is a bike chainring designed to improve chain retention and pedalling efficiency. Reliable engagement and a stiff construction make long rides feel more controlled and maintenance simpler. Is the ring right for riders who need a 104mm BCD single-ring conversion?
⚡ At a Glance
- • Chain Retention: Narrow-wide tooth profile increases contact with the chain for secure seating
- • Best for: Cyclists fitting a single-ring setup on 9/10/11-speed drivetrains with a 104mm BCD crank
- • Not ideal for: Riders whose cranks use a different BCD or who require a double chainring configuration
36T chainring with 104mm BCD made from 7075 T6 aluminium. Narrow-wide teeth and CNC machining suit 9/10/11-speed chains and most Shimano and SRAM cranksets.
Stronger power transfer - With 7075 T6 aluminium and 4mm plate thickness
7075 T6 is an aerospace-grade aluminium alloy paired with a 4mm plate thickness to reduce flex under load. Stiffer construction limits deformation during hard efforts, keeping the chainring true to the crank.
Sharper response to each pedal stroke and more efficient power delivery, especially when climbing or sprinting.
Lower friction and longer life - With narrow wide tooth design
The narrow wide tooth profile alternates narrow and wide teeth to match inner and outer chain links, increasing engagement surface and reducing lateral movement. This geometry helps teeth seat fully into the chain while lowering wear and noise.
Quieter running, fewer chain drops and extended wear life, which reduces maintenance frequency on long rides.
Straightforward upgrades - With 104mm BCD compatibility
A 104mm bolt circle diameter follows a common standard found on many road, MTB and BMX cranksets. Design suits direct replacement on compatible Shimano and SRAM cranks without specialised adapters.
Simple swap-in for many cranksets, making conversion to a single-ring drivetrain fast and practical.

🏆 Our Verdict
The CYSKY Chainring 36T suits riders converting to a single-ring 9/10/11-speed drivetrain who need a durable, stiff component. Aerospace-grade 7075 T6 construction combined with a narrow-wide tooth profile reduces flex, wear and noise while keeping the chain secure. While initial cost varies between sellers, long-term durability and reduced maintenance make it a worthwhile upgrade for frequent riders.
