Its how you like the bike to ride like a good set up is a really nice geo of the bike Like on my zoo I have.. Monty riser bars, Echo stem, Echo forks, Adamant cranks Profile rear hub on a smashed up dh36h rim, Hope pro II frunt hub on a Tryall rim drilled And 04 maggies Really good set up for my liking feels nice rides nice and its lighter then what it used to be
