45NRTH utilizes a two-piece construction method to create a reliable and high-performing bicycle tire stud with a concave carbide-aluminum design. The open space and edges created by the large concave crown result in twice the surface area for increased traction and grip. - Concave tip for traction, durability, and longevity - Aluminum base to save weight - Compatible with 45NRTH stud insertion tool - Compatible with all studdable 45NRTH tires - 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.

A new standard in tubeless sealant. Finish Line Tubeless Tire Sealant, featuring Fiberlink technology, will not cure inside the tires and doesn’t need to be refreshed every few months to maintain effectiveness. This sealant will last the entire usable life of the tire. Since there is no liquid latex or ammonia in Finish Line sealant, it is naturally non-toxic, hypoallergenic and safe for carbon fiber rims. Additionally, Finish Line Tubeless Tire Sealant cleans up easily with water – no more scrubbing or scraping cured latex from tires and rims. Fiberlink technology makes this possible. Utilizing DuPont Kevlar fibers, Fiberlink seals are extremely robust once they plug a hole. When a puncture happens, fibers rush into the wound and quickly stop air loss. As the tire flexes while it is ridden, the Fiberlink mesh tightens and reinforces itself, creating a confidence-inspiring seal that will last ride-after-ride. - Non-latex ammonia-free formulation - Kevlar reinforced Fiberlink mesh seal - Seals up to 1/4" punctures - Can be used in extreme temperatures, down to -10 degrees Fahrenheit

Built with Kevlar to deliver faster and stronger seals, FiberLink represents a new standard for tubeless bicycle tire sealant. Developed with Finish Line's proprietary FiberLink Technology, this groundbreaking pro latex formula seals quickly, ensures maximum seal integrity and delivers optimum longevity. - FiberLink Technology utilizes Kevlar fibers that work synergistically with fast-acting natural latex to seal punctures as they occur. Free-flowing latex cures rapidly to create an adhesive seal which is reinforced with interlinking Kevlar fibers - Low viscosity is ideal for race conditions - Fast-acting natural latex reduces air loss - Optimum longevity between refresh cycles - Low odor and easy to setup - 8oz Drip Bottle

- The original tube for flat protection - Non-toxic and environmentally safe - Protects against punctures up to 1/8-inch
