Product Details

One speed's all you need? This 29er keeps the weight low and stiffness high, so the energy of you tugging on the handlebars makes it through that one gear and down to the ground.

FACT 11m carbon HT singlespeed frame is engineered with a stiff, tapered head tube, horizontal dropouts, and 29" race geometry for pure speed
S-Works carbon single-bolt 27.2mm seatpost takes this already featherweight package to its absolute minimum without sacrificing stiffness or strength
Custom Specialized/RockShox Reba S29 fork is the lightest, stiffest performance XC fork, featuring a tapered carbon crown/steerer and Reba Team lower with titanium motion control damper and Floodgate adjuster
