What customers say
Customers overwhelmingly praise the 45NRTH XL Concave Studs for delivering exceptional, confidence inspiring traction. The unique concave design significantly outperforms standard studs on ice and hard snow, providing a dramatic increase in stability and control for treacherous winter riding. This superior grip is viewed as a crucial safety benefit. While the carbide tip durability is excellent, the primary friction point is cost. Because many studs are needed, the total investment is substantial, causing some to question the value despite acknowledging the superior performance. Installation requires the specialized tool; users attempting manual fitting often report frustration and subsequent stud loss. For dedicated winter cyclists prioritizing maximum grip, these studs are an essential, high performance component.
Know before you buy
The concave shape creates a sharper edge that bites into ice more effectively than a flat or rounded tip. This design increases surface contact, providing significantly better traction on slick, frozen surfaces.
Yes, these studs are designed to be installed using the 45NRTH stud insertion tool. Using the proprietary tool ensures the studs are seated correctly without damaging the tire casing.
The XL version features a larger carbide tip diameter. This increased surface area provides more aggressive grip, making them ideal for riders tackling particularly challenging or icy winter terrain.
These studs are specifically engineered for 45NRTH studded tires that feature pre-molded stud pockets. They may not fit or stay secure in tires from other manufacturers.
The carbide tip provides the necessary hardness to grip ice without wearing down quickly, while the aluminum base keeps the overall weight of the tire low. This combination offers the best balance of durability and performance for winter riding.
