2027 BMC Fourstroke R 01 One

When race engineering meets full-gas fun, you get the Fourstroke R 01 ONE, a race-bred full-suspension mountain bike that makes winning feel inevitable. Engineered in our Impec Lab and sharpened on the race circuit, it is built around the 01 Premium Carbon frame for the ultimate efficiency and instant response on climbs, while progressive XC race geometry lends confidence when speed builds and lines blur. The dark magic of APS suspension works in the background, keeping traction high and momentum intact through rough, technical terrain. The Autodrop dropper lets you commit to the descents without hesitation. 120 mm of Öhlins suspension front and rear, our clean ICS Carbon XC one-piece cockpit, and a full XTR Di2 drivetrain and brakes ensure unrivalled race performance. Duke Lucky Jack SLS5 wheels then complete a build designed for one thing: going faster, more often.
