REX1.2 BCD 110/60
ROTOR believes that functionality and reliability — not fashion — best
define material selection when it comes to crafting 1x and 2x REX1
cranks. Crank arms CNC-machined from aeronautic-grade 7055
aluminum are combined with proprietary technologies to yield cranks
with an exceptional stiffness-to-weight ratio that can handle a thrashing
off-road. Together with ROTOR’s Universal Bottom Bracket (UBB)
system, ROTOR cranks offer a performance upgrade opportunity for
almost all mountain bikes on the market.
