I was just wondering:

In the case of moderate riding in a dry and clean environment, is it necessary to disassemble and execute maintenance work on headset at certain periods or km of riding?
I am asking because headset maintenance works for a bike with hydraulic disk brakes with internal routing and integrated handlebars is a nightmare: you have to disassemble the hoses, then cut their end at the brake caliper and use new “stealth-a-majig” olives and barbs for re-assembling. It is a long and expensive process; furthermore, if you do it 2-3 times, the hoses become too short and you must change them completely – another complication…
