Similar in design and function to its Niner BioCentric II counterpart ? but compact for use in most PF30 shells ? the Biocentric 30 makes adjustments easy across a wide range of gears and eliminates the need for adjustable dropouts. This gives riders the cleanest possible solution for singlespeed use on a PF30 compatible frame ? no bolt on hubs, no chain tensioners, no brake adjustments with gear changes. The sealed bottom bracket is integrated into the cups of the BioCentric 30 and is capable of handling most 24mm spindle cranks.
The BioCentric 30 offsets the bottom bracket spindle 8.5mm from center, offering greater range of adjustment compared to a more traditional EBB setup. More offset is a boon when changing gears without having to change chain length and it allows riders to make more noticeable changes to frame geometry via BB position.
