Trek Speed Concept SLR 7 AXS Serpentine 2027 time trial triathlon bike

The Speed Concept SLR 7 AXS Serpentine Trek was designed with one simple idea in mind: to save you time with every pedal stroke. Its 800 Series OCLV carbon frame and KVF aerodynamic profile work in tandem with highly integrated handlebars, fork and storage solutions. Added to this is IsoSpeed technology, which provides greater comfort as the kilometres mount up. On a triathlon bike, every detail counts, and the Speed Concept has been specifically designed to ensure nothing disrupts your effort.

The wireless SRAM Force AXS E1 drivetrain with power metre delivers precision and simplicity, whilst the Aeolus Pro 51 ‘ Bontrager ’ carbon wheels give the whole bike the look and feel of a true time trial machine. Add a highly adjustable riding position, integrated hydration and nutrition management, and high-performance disc brakes: everything comes together to create a machine capable of helping you chase those seconds, whether in a long-distance triathlon or against the clock. The Speed Concept SLR 7 AXS is the sort of bike that makes you want to see just how far your legs can take you.
