Bontrager R4 Classics

While the R4 Classics are built for durability on rough surfaces, they are tubular tires designed specifically for performance and racing. If you are looking for a daily training tire, a clincher setup is generally more practical and easier to maintain.

Hard-Case Lite offers a solid balance between puncture resistance and weight, making it effective for road debris. However, because this is a performance-oriented tire, it is not as armored as heavy-duty touring tires and can still be susceptible to cuts from significant road hazards.

No, these are tubular tires, which require specific tubular-compatible rims. They are glued or taped onto the rim rather than hooked into the sidewalls like standard clincher tires.

The R4 Classics feature a high-grip tread compound specifically engineered for confidence in both wet and dry conditions. The supple casing helps the tire conform to the road surface, which significantly improves traction when cornering on slick pavement.

A 38mm valve is standard for many shallow-profile rims, but it may be too short if you are using deep-section aero wheels. You will likely need to purchase valve extenders separately if your rims have a deeper profile.
