2027 BMC Twostroke 01 One

From XC blasts to grinding out off-road epics, the Twostroke 01 ONE is here for it all. The frame is 01 Premium Carbon – super lightweight, direct, and developed through years of BMC XC racing. The geometry is modern without being dramatic: a steep seattube angle gives more traction on the toughest grades, whilst the longer reach and fork trail brings confidence when speed builds and lines get loose. Proving it’s race-ready, the plush, tunable Rockshock SID SL Select 3P suspension handles the front end, while SRAM GX Eagle AXS with Full Mount rear derailleur provides efficient power transfer, shifting under stress, and braking. It rolls on our lightweight XCD 30 Carbon wheels with a 30mm internal width to give you all the tire volume you’ll need. Versatile by design, run it with a 100 mm fork for pure XC, or push it to 120 mm and let it blur into something rowdier.
