56,000 miles and I still have not broken a chain on my mid drives, including our tandem. cheap parts, cheap wheels, crappy tires are far more of an issue for most. never even broke one on my recumbents years ago.
man I have had thousands. My bike is underground in my shop I start my Garmin, and it can go off 20 times more with nothing moving. It seems when I am not moving. I used to get it when I first started riding one parked car would set it off. This is over 3 separate units on different GPS's
The Banger radar is not as sensitive. That can be a good thing. I don’t have all the false alerts when I am not moving like I get on the Garmin. Or as many cars off to the sides. But the Banger has stopped letting me turn off the light with the GPS. It defaults to full on. I have to manually...
I hate when I put on a new chain and I get skipping. On the tandem, it’s really a pain. So I try to have all the replacement cogs on hand. We can wear out a 13t in 2 to 4 thousand miles.
I have worn out many 13t cogs on the tandem. The 11t sometimes, this last time a 15t. Some of those can be replaced when you hit the bigger ones. You’re stuck on cassettes.
