BB90
BB90 is the widest bottom bracket available on a road bike. This Trek-exclusive carbon BB makes the frame lighter, stiffer, and quicker to accelerate.
DuoTrap compatible
DuoTrap seamlessly integrates the computer sensor into the frame to measure speed, distance, and cadence with no added aerodynamic drag.
E2 head tube and fork
E2 head tube tapers from a 1.5" lower to a 1-1/8" upper, placing more material where it matters most for the lateral rigidity of a 1.5" system without the added weight.
3S integrated chain keeper
Our 3S chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless shifting even on rough roads and under heavy loads.
IsoSpeed decoupler
A technological revolution. IsoSpeed isolates the seat tube from the rest of the frameset, doubling compliance and comfort with zero performance drawbacks.
IsoSpeed fork
It's a one-two punch: generous ride-tuned sweep and shape increases compliance for greater comfort, and unique dropout placement optimizes the wheelbase.
400 Series OCLV
Ultra high performance, within reach. The areal weight range and modulus mix of 400 Series OCLV provides an exhilarating sense of acceleration and confident handling.
Crank: compact
Two front chainrings with shorter gearing, for the best combination of climbing ability and flat-terrain speed.
