Are you guys seriously still using electronic groupsets thinking theyre going to last as long as your mechanical ones? Newsflash: theyre not. And dont even get me started on the so-called water resistance of these components. Ive seen more durable toys in a toddlers playroom. Whats the point of shelling out top dollar for a Di2 or EPS system if its just going to fail on you the moment it gets a little wet or dirty? Can anyone seriously claim to have gotten more than 5 years out of their electronic components without having to replace at least one major component? And dont give me any of that its all about maintenance nonsense. Ive seen guys who baby their bikes and still have to deal with faulty shifting and dead batteries. So, whats the secret to making these fragile components last? Or are we all just throwing our money away on fancy electronics that are destined to fail?
