“Why would anyone make custom derailleurs when modern electronic shifting works extremely well? It’s a bit like driving a car with manual transmission even though the latest automatics are very sophisticated. It’s about being involved in the operation of my bike, rather than just pushing a button. There’s a joy in feeling the gears engage perfectly because I – and not a computer – timed the shift perfectly.”
