Got a new bike in early December but only 1500 miles on it due to Covid recovery. Took off the chain and cleaned it yesterday. Hung it on a nail alongside a new and degreased chain. Zero wear. Both were exactly the same length. I guess I have no wattage or the Silca wax is doing its job. At $75 per chain, $400 per cassette, and $881 for rings, I'm not guessing on chain wear. It ain't take no rocket surgeryist to remove no doubt. 0.4% and they are in the bin. I have cassettes with over 30,000 miles that are fine.
Pads? I am halfway thru my second set!! I am either fat, brake too much, disc brakes suck, too much rain, too much salt on the road, it is too hilly here or a combination of these.
