The cause of your damaged cassette is starting in the high gears.Folllowing up on my posts about about my Allant 7s skipping....1st not at all happy with the shop! After they worked hard to find answers they called and said it was ready yesterday. I was not able to pick up till today. My usual tech Steve was not in As he said when he called yesterday. The repair was replacing the cassette again. It was worn after 500 miles.
The issue from my side was when I picked up last time for the same issue the 1st time it skipped after they replaced the chain and cassette was it skipped on the 1st ride 2 miles of riding. I rode the bike maybe 6 times and it got worse., still rideable just not fixed correctly. Today I was told they were only going to charge me for the cassette, 33 and change. I was pretty upset since i paid retail for the bike continue to pay every time they service it (why buy local?) but once where I received my free 1 month service and that was the 1st time it skipped! I don’t believe they made it skip (maybe they did??) because the part was very worn but if it wasn’t fixed the last time it seems the cassette was defective.
I was told the reason was I only rode in the last 2 gears and at 64 years old how to drive a manual shift car. I learned to drive on 62 Falcon 3 in the tree. My response was I knew how to shift but most of my time is in the upper gears on the gorgeous Silver Comet Trail, 3 miles from my house, a relaively flat rails to trails with few stops on my 75 to 103 mile rides, why would I shift so much or use lower gears for take off when I am going along on a “highway” style trail? Same reason it is on hi power most of the time. “don’t you slow down when near other people.” The answer was yes, usually twice as few other people are out there during retired hours, no reason for excessive shifts. The trail is awesome , one of the main reasons retiring here near Atlanta.
I was told these are regular bike parts and if I needed service again I was to bring in ebike parts and they would replace it but otherwise implied to what I heard I was done with service. On the way out I muttered to sales dept “ I was told to not come back!” I have not tested the bike , not sure if is really fixed yet!
I intend to follow up with emails to to Trek and owner/president of the chain and if I can get a bike form another shop , probably a Vado I will be selling this and the 2 additional batteries which includes the piggyback attachment sharing the external batteries. Way to go make a customer happy about buying 6grand of a bike!
You’re supposed to be in the lowest(easiest)
gears when stopped and as you start pedaling then up shift. When you start moving from a stop in the higher gears you put immense strain and your weight on the cassette teeth causing them to get chipped, mashed and bashed.
You also shouldn’t be riding in turbo all the time. Even at 64 years old you can be in “tour” mode and 5th or 6th gear and you will easily be cruising along at 20mph with minimal effort.
I’m sorry but the problems you described is due to your incorrect (lack of) shifting. Even on a non-electric bike you would have broken your cassette. If you sell your trek and get a Vado and continue the same style of wrong shifting you will break that drivetrain too.
