We have one bike with Shimano brakes in this house. The others are Hope and they work beautifully, require almost no maintenance, a set of pads once in a blue moon (same shape of pads as 5 or 10 years ago too), and have a wonderfully progressive feel.
We have one set of Tech X2s that must be 14 years old. Still the current pad shape. Still working fine. Been to the alps a few times. Enough power no repairs needed.
Shimanos are cheap I suppose. Though their discs are made of cheese – don’t use a Shimano disc with a Hope brake or it’s life is best measured in hours.
If anyone wants to take them off my hands for a nice set of secondhand Tech X2 or E4 brakes then PM me.
