Shimano hardware seems really reliable from my experience and their warranty is exceptional.
Shimano have been asleep at the wheel for years in terms of performance and quality.
Also their warranty solution is to give you a whole new thing to replace your broken thing which then goes straight in the bin. I’d rather have spare parts availability and the option to repair expensive components.
This is annoying for brakes and drivetrains but now they’re applying the same logic to e-bike components which are vastly more expensive and packed with non renewable, rare minerals and heavy metals.
I won’t consider an e-bike until owners have the right to repair.
