Upgrad your bottom bracket to the DRS system! Vocal’s patented DRS bottom bracket design is a bit of an industry first in that it has the ability to add resistance to the axle in order to stop the cranks spinning out of control when performing limb tricks.
set includes: 1x DRS 3 screw adjustment with drag washer for the non drive side, 2x CNC alloy 3mm spacer shims, 1x Hex Key
