ethirteen Sylvan Race Carbon e*spec All Mountain Wheels - Superboost 157 Rear Info
The Sylvan Race Carbon e*spec All Mountain Wheels – Superboost 157 Rear from ethirteen are purpose-built for modern light e-MTBs that demand strength, control, and a lively ride feel. Featuring ethirteen’s first-ever asymmetric carbon rim design, these wheels are engineered to handle higher drive torque and system weight while maintaining the compliance and traction riders expect on technical trails.
The 30mm internal-width asymmetric rim uses a low-profile shape to increase vertical compliance, absorb impacts, and reduce rider fatigue over long days. By equalizing spoke tension between drive and non-drive sides, the asymmetric layout improves durability and consistency—key for aggressive trail riding and fast descents. A refined valve dock interface enhances tubeless sealing, while quality spokes and alloy nipples contribute to a controlled, responsive ride.
