Formula R1 Disc Brake

As the lightest serial disc brake ever made the R1 is the premier XC race brake on the market today. Custom tuning drops the stock weight of 298 grams by further 16 grams.

Despite its low weight, the R1 generates more than enough power and performance for an All Mountain or Enduro use. The forged master cylinder body and caliper provide increased modulation, braking power and durability, while the R1’s patented caliper piston system increases fluid capacity in the caliper providing stability and fade resistance even on long descents.

"Only DOT 4 fluid can be used on formula brakes"

Please note, disc brake rotor bolts are NOT included.
