2026 BMC Twostroke 01 One - Copper White / Firestorm
BMCBuilt light, ridden hard: the Twostroke 01 ONE is race-ready XC hardtail made for riding faster than planned.
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.
Features
Radical race geometry

Blast the turns. Rip the rock gardens. There is less reason to back off with a frame that can take 100-120mm forks. The slacker head angle and longer reach make you unstoppable.
ICS Carbon XC one-piece cockpit

La velocidad no solo depende de la rigidez o de ahorrar gramos. En el cockpit ICS Carbon XC de una pieza diseñamos una flexión controlada para mayor sensibilidad. Es como ganar unos mm extra de absorción frontal… o un par de codos adicionales.
Full Mount (UDH)

You can read "Full Mount/UDH" as futureproof. This gear hanger system means multiple options for your build. Want a hangerless Full Mount 1x setup? You got it. Your dream build has a derailleur hanger groupset? No worries. More options, more potential.
Dropper post compatible

Not only does this seattube design accommodate both our BMC D-shape seatpost through to standard 27.2 mm models, it's also dropper post-compatible and ready for straightforward internal cable routing. In short: you choose how you want to ride.
