TECHNOLOGY

IsoSpeed Fork

It's a one-two punch: generous ride-tuned sweep and shape increases compliance for a smoother ride, and unique dropout placement optimizes the wheelbase.

Blendr-compatible stem

Bontrager Blendr stem technology lets you clip your gear directly to the stem for clean looks, maximum user friendliness.

Endurance Fit

As befits the world’s most advanced endurance racing bikes, we’ve developed the world’s most stable racing geometry. Still racy, but with a slightly higher head tube for better stability and greater comfort through the entire ride.
