Maxxis Aspen ST Tubeless Ready 29"

The Maxxis Aspen ST Tubeless Ready 29-inch tyre (nicknamed "Fastpen") is the ultimate XC and Short Track semi-slick MTB tyre for riders seeking pure speed on dry, fast-rolling terrain.

Engineered to deliver exceptional efficiency and break speed records, it combines an ultra-low-profile tread pattern along the center with slightly raised shoulder knobs to maintain cornering traction without ever slowing you down.

Featuring the latest silica-enriched MaxxSpeed compound, this tyre reduces rolling resistance by 25% compared to previous 3C generations. Combined with cut-resistant EXO Protection sidewalls and a high-performance casing (120 TPI), it is the ultimate weapon for shaving off vital seconds in Cross-Country racing.
