Chainring, Gates CDX, STePS spider, 39T

Optional 39t front sprocket for Nexus 5s Di2

The 39t front sprocket is meant for lowering the gear ratio just a little, to either move the use pattern to heavier gears or for a higher cadence. Shimano E-bike systems will need to be reprogrammed when installing this 39t sprocket - Contact either us or Shimano for this. 
42t is the standard oem size for Nexus 5s Di2.
