This revolutionized racing machine arrives with integrated protection and is designed around the progressive BMC geometry, now accommodating two water bottles in the front triangle for long-distance missions. Stay ahead of the competition with the Fourstroke 01 TWO matched with a SRAM Gx Eagle AXS drivetrain, RockShox SID SL Select+ fork and RockShox SIDLuxe Select+ shock, DT Swiss XR 1700 wheelset with 25mm inner width and the BMC Autodrop integrated dropper seatpost.


Your all-new secret weapon provides the first ever fully integrated, automatic dropper post for on-the-fly and squat-free seatpost dropping to push further faster, even on the most technical XC courses.
