Sudden Shifting Problem FOUND: Cassette damage! #mtb

I've been running the factory gearing on my eMTB for over a year. For the past few months I've been testing a new wireless shifter. It was all going great until suddenly I had problems shifting between a few gears. Suspecting I needed to finely tweak the wireless derailleur I ended up on a week long cycle of settings changes that made everything even worse....until I looked at it from a different angle and found the problem. My cassette has damage that affects some of the key gears. This video shows how I found it and what I did to resolve the problem. 8-speed cassette seen in video - https://amzn.to/48O8STi Oumers cassette tools - https://amzn.to/4nE1ajr (note: as an Amazon associate I may earn from qualifying purchases) for Coupon Codes, Merch, and 🆓 promotions - Check out the links below: ✅ T-Shirts - https://kevcentral.store ✅ Stickers - https://www.ebay.com/usr/kevcentralmerch ✅ Bike Parts - https://www.amazon.com/shop/kevcentral ☑️ Patreon - https://www.patreon.com/kevcentral ☑️ Twitter - https://www.twitter.com/kevcentral How to become a channel Member: https://www.youtube.com/channel/UC_mxl2kDiu-Ls_m7dR5qjtw/join Discounts at Mendham Bikes: https://mendhambikes.com COUPON CODE for 5% off anything on site: KEVCENTRAL COUPON CODE for 20% off Univega Rover Mesa: KEVCENTRAL20 COUPON CODE for 35% off Vitesse Flare: KEVCENTRALFLARE Great Folding eBikes: https://alnk.to/44QFVGP HP printer owner?
