Description
High-Speed Gravity Performance for Downhill and Enduro
The iXS Attack FSX Tire is a high-performance gravity tire designed for riders who want maximum control, durability, and speed on demanding terrain. Developed with input from 5-time Downhill World Champion Aaron Gwin, the Attack FSX combines modern tire technology with a versatile tread design that performs across a wide range of trail conditions.
Designed for both downhill and enduro riding, this tire offers dependable grip from dry hardpack to wet and technical trails. Its reinforced DH Core casing provides the durability needed for aggressive riding, while the fast-rolling tread design keeps momentum high on long descents and fast sections.
The Attack FSX is especially effective as a rear tire when paired with a more aggressive gravity tire on the front, but it can also be used on either wheel depending on rider preference and terrain. With its balance of speed, stability, and reliability, it is built for riders chasing high-speed adventures.
