Bontrager's R4 Road tire is perfect for training, racing and everything else! The round profile and lightly textured tread offer low rolling resistance and grip like glue in the corners. The 220tpi casing and folding beads deliver a wonderfully supple ride and lighten the tire considerably. You also get sub-tread protection against flat tires and equally impressive, Bontrager's unique aero wing design that improves airflow so that the R4 actually saves you energy on every ride, too!
The 220-thread-per-inch casing makes this tire conform to the road for superior cornering and a smoother ride.
This is a folding tire.
