DT Swiss 240 Classic EXP OS Hybrid Rear E-MTB Hub

A hub built for an extended eMTB adventure.

The latest 240 Hybrid hub incorporates special components like the DT Swiss Ratchet EXP® OS system with 30 teeth to ensure reliable power transmission from both the rider and the motor to the ground. The drive side bearing is bigger and the hub flange is enlarged. The spoke holes are expanded, purpose-built for 2.34 mm DT Swiss spokes, which deliver enhanced resistance to acceleration and braking torques. Crafted from hardened steel, the freehub system further reinforces the hub's resilience, allowing for extended and trouble-free eMTB rides.

Features:

• With the use of a single cylindrical spring, the system wears less while allowing faster full engagement
• With full 30T engagement, the force generated by the motor and rider is transmitted evenly over a wide contact area, allowing for superior reliability
• A bigger double thread spreads the loads across a larger area, reducing peak loads, contributing to the longevity of the system and even allowing more torque to be transmitted
• Larger bearings with larger balls spin fast and better absorb the additionnal axial and radial loads from the eMTBs
• The axle was tested in FEM-strength analyses in order to determine the bending loads that occur when riding an eMTB and to optimize the axle resistance
