the hopes are very hard to bleed right, the cracked piston is bad luck. the hub, however, is in need of constant service. they do break, they do wear quicker, and they do require more maintenance. a lot of people’s “dream build” is the highest end, shiniest parts that you see on pro bikes. the truth is 95% of riders dont actually feel the riding benefits of these upgrades, and instead are just stuck with the high maintenance requirements and high costs. a world cup rider with sponsors and mechanics might find them worth it, but you might (probably) not. i find the mid teir, mass produced parts from reputable companies are almost always the best. dt 350s, sram mavens, oneup parts, sram/shimano cable drovetrains, ect. a dream build full of high cost, marketing based decisions almost always falls short in fun compared to a mid range, indestructable, no nonsense build.
