Riders with the new PF4130 design can use this kit to install a DUB crank. It is important to note that the inner race must be recessed roughly 2.8mm to provide clearance for the dust cover. this is the key change on the new PF4130 that began shipping in 2018. if the inner race (and seal) are flush with the outer race the Bottom Bracket cannot be converted for use with DUB cranks.
