Neutron Hollow Carbon Chainring | 11/12s | 50-34/52-36 | From 129g!
Carbon hollow construction | Aluminium+carbon composite | BCD 110 4-bolt
50/34 ~ 129g | 52/36 available | 11 and 12-speed compatible
The hollow internal structure removes material where it isn't needed, keeping weight down without hollowing out the rigidity that determines how cleanly power transfers and how crisply the front derailleur shifts.
The result is a 50/34 chainring set at 129g with shifting that feels direct and positive under load.
The chainring body uses a hollow carbon construction rather than a solid plate.
This removes dead weight from the mid-section while keeping the ring rigid where it matters.
The teeth are aluminium for durability and precise chain engagement, while the body is carbon for weight savings.
Standard 110 BCD 4-bolt pattern, covering the vast majority of current compact and mid-compact road cranksets.
Compatible with Shimano 11-speed and 12-speed cranksets and chains.
