Description
The MCS 104BCD Chainring is a race-focused four-bolt chainring for riders running a compatible spider and wanting clean, precise gearing without adding unnecessary bulk.
CNC machined in the USA from a solid piece of aluminium, it is built to stay light, strong and properly round so chain tension remains consistent through the pedal stroke. That matters when you are trying to get power down cleanly out of the gate rather than fighting a tight spot in the chain.
Simple race hardware, made properly. Check your bolt pattern before ordering.
