EX 1700 Classic 27.5" Boost Rear Wheel

The DT Swiss EX 1700 Classic 27.5" Boost Rear Wheel is a hard-charging trail/enduro MTB rear wheel built around DT Swiss’s proven hub platform and a tubeless-ready alloy rim for dependable speed, grip, and durability on rough terrain. Its asymmetric, welded rim helps balance spoke tension for a stronger, longer-lasting build, while the 350-series 6-bolt hub with the 72T Ratchet DEG System delivers fast, positive pickup when driving out of corners or ratcheting through technical climbs.

Key ride-critical details

• Tubeless-ready alloy rim - Runs lower pressures for improved traction and reduced pinch-flat risk; rim tape and a tubeless valve come factory installed for a cleaner setup
• Asymmetric welded rim design - Helps equalize spoke tension for better impact durability and more consistent long-term trueness
• DT Swiss 350-series 6-bolt rear hub - A service-friendly, widely supported hub standard for modern disc-brake mountain bikes
• 72T Ratchet DEG System - Fast engagement feel for technical riding where timing and pedal control matter
• Degrees of Freedom installed (0/10/20°) - Easily adjustable on/off pedal kickback behavior to tune drivetrain feel to suspension kinematics and riding preference
• Competition Race J-bend double-butted spokes with ProLock Squorx alloy nipples - Strong, fatigue-resistant spoke choice with thread-locking nipples to help the wheel stay tight under repeated hits
