I'm going to build a training road wheelset for my touring bike. I wonder what should be criteria for choosing hubs and rims and spokes. I'd prefer cheaper options as long as they are durable and not too heavy.
Hubs: which are considered serviceable as opposed to disposable? And which require relatively little maintenance? My bike has 135mm rear dropouts, so I need MTB rear hub, but for front - search for MTB or road?
Rims: there are many budget models with slight variations in weight and strength. I'd like to find one with maximum
strength / weight ratio, but how can I estimate the strength? Say, AlexRims DA22 is advertised as butted but it weights same as 1.5x cheaper Mach1 non-butted rims. Is butted any better if it's not lighter?
