Carbon MTB Wheels 27.5/29er with DT Swiss 240 Boost Hubs

Saykya Carbon MTB Wheelset 27.5/29er Boost, DT Swiss 240 Hub, for Mountain Biking

Built with legendary DT Swiss 240 Boost hubs and high‑modulus carbon rims, this wheelset delivers unrivaled stiffness, instant power transfer, and lightweight performance for XC, Trail, and Enduro riding. Featuring the reliable Ratchet EXP freehub system, wide Boost spacing (110×15 front / 148×12 rear), smooth sealed bearings, and tool‑free maintenance, it offers superior durability, precise engagement, and stable handling on rugged trails. Available in 27.5" and 29" sizes, tubeless ready, and compatible with most MTB drivetrains. Dominate every climb, corner, and descent with true Swiss precision.

Hub maintenance:

• Standard using: every 1,000–1,500 km or 3–6 months (whichever comes first).
• Harsh Conditions (wet, muddy, dusty): every 500 km or monthly.
• Check after riding: clean externally after muddy/rainy rides to prevent grime buildup.
• Warranty period: 1 year, don't include bearing, gear ring.

Sapim cx-ray spokes, with their excellent aerodynamic performance and superior overall quality, have become the preferred spokes for many major bicycle wheel manufacturers, and are widely compatible with various types of bicycles, including road bikes and mountain bikes.

Features:

• Aerodynamic Optimization: Spindle-shaped cross-section for ultimate wind breaking
• Lightweight and Tough: 10% weight reduction, tensile strength exceeding 2000MPa
• Precision Engineering and Durability: Patented anti-loosening spoke caps, compatible with multiple vehicle models
