Lugging a Motor, Why it's Bad

[Jeremy McCreary]

I just checked again, I'm over 2,000mi. on a 1,000 watt mid drive and some of the links are less than .5% and some are slightly over. I guess the chain does not wear evenly. I think I can stretch it (excuse the pun) to 3,000mi.

Why accelerate the wear on your cassette, pulleys, and chainring for the cost of a new chain — especially with a high-powered mid-drive in the mix?
