Aspen ST 700 x 55 HYPR-X/EXO/TR Black

The Maxxis Aspen ST 700 x 55 is a fast-rolling, high-volume gravel tire built from Maxxis’ short-track XC heritage tuned for riders who want speed on hardpack and efficiency on long mixed-surface days, without giving up cornering confidence.

Its HYPR-X rubber blend combines road- and MTB-derived compound tech to target lower rolling resistance while maintaining predictable grip when the pace rises on loose-over-hard or dusty turns. With EXO sidewall protection and a Tubeless Ready (TR) design, it’s well suited to modern gravel setups that prioritize control, puncture resistance, and lower pressures.

• 700 x 55c high-volume sizing - Added air volume supports lower pressures for comfort, traction, and stability on rough gravel
• HYPR-X compound - Engineered to reduce rolling resistance (claimed 25%) while improving cornering traction (claimed 19%) for a faster, more confident feel
• EXO sidewall protection - Extra defense against cuts and abrasions in rocky or sharp-edged gravel conditions
• Tubeless Ready (TR) - Designed for tubeless setups to help reduce flats and improve ride quality at lower pressures
• Aspen ST-inspired tread design - Prioritizes speed on hardpack and mixed gravel with predictable handling when leaning the bike into turns
