I regularly use my Turbo Vado 4 about 3x per week and cover an average of 100km per week. I maintain my bike meticulously and in particular look after the drive train making sure it’s clean and lubricated every week. So now that it’s done 2000km in 5 months I see that the chain (KMC e10) has worn by 0.5% but has not reached 0.75% according to the Park tool chain checker. New chain is on order so that the cassette and/or chain ring get some more life. Wondering how many miles others are getting from their chains ? My rides have been predominantly on tarmac roads with no excessive dust/grit.
