Available in two arm lengths, both the long 108-millimeter and short 85-millimeter Box One Brake Arms are cold forged and CNC-machined from 6061-T6 aluminum. Cold forging produces the strongest, stiffest, lightest weight and most durable bicycle parts. Both sizes feature 35 millimeters of vertical brake pad adjustmentâ€”more than most linear-pull brakes. Other features include precision sealed bearing pivots, titanium and stainless steel hardware, a flexible cable noodle and streamlined cable fixing point. The long-reach brakes are excellent for BMX, mountain, city, urban and tandem bicycles using linear-pull-compatible levers. The 85-millimeter â€œMini-Vâ€ brakes are an excellent choice for cyclocross or drop-bar gravel bikes.
