Elite IsoZone VR-SF – Goodbye, chatter

Bone-jarring pavement is no longer a problem with the Bontrager Elite IsoCore VR-SF drop bar. Directly into the bar's top section integrated IsoZone foam pads absorb up to 20% of vibrations, reducing wrist fatigue.

While IsoZone technology enhances the ride comfort of the handlebar, which is made from lightweight 6066-T6 aluminium, the Variable Radius Shallow Flare design (VR-SF) with its shorter Reach ensures easier brake lever access and a correspondingly superior riding feel.

Clean internal cable routing is provided by Di2-compatible connectors, which also allow the Shimano EW-RS910 Junction Box (sold separately) to be mounted in the bar end.
