Versatile and confidence inspiring, the Gravdal securely navigates through harsh winter conditions with concave carbide studs for added traction in icy conditions.

• Siping creates a more conforming lug for added traction
• 216 steel carbide studs provide traction in the iciest conditions
• Fits most bikes with cantilever or disc brakes
• 33 TPI
• We design 45NRTH tires for extreme winter cycling applications. We do not recommend this product be used with power assist bikes as the additional torque and system weight can lead to pre-mature casing wear and stud loss.
• Always check with your rim manufacturer to verify rim & tire compatibility before assembly or use
