Replacement for my 40T
I bought a 42T to replace the 40T front chain ring on my 1x11 gear-set and it did the trick in terms adding a few MPH to the top end. Easy installation too.

The RX810 singlespeed front chainring for 1x11 GRX systems by SHIMANO does without unnecessary shift pins for a lower weight. Instead, the GRX chainring features SHIMANO’s DYNAMIC CHAIN ENGAGEMENT+ tooth profile, keeping the bike chain in position on rough terrain. Thanks to different chainring sizes available – ranging from 40 to 42 teeth – it’s up to you to decide which intended use you want to equip your gravel cross and commuter bike for.
