Is a dirty chain a drag?
Well, actually, no. At least according to Ceramic Speed and GCN


The TL;DR version: A fairly filthy chain adds about 1 watt of drag over a clean new chain. Simulated rain adds around 0.5 watts. It would have been interesting to see what would happen with an unlubricated chain.

Bottom line, it seems that all the murdered electrons over chain lubrication have died in vain.
