The new 240 hub with Ratchet EXP: lighter, stiffer, more precise and easier to maintain.
Swiss precision engineering, machining and assembly together with clever detail solutions have made of the 240 what it is today: A legend. The strengths of the new 240 hub are further enhanced with the new RATCHET EXP technology. The ultra-reliable freehub system transfers the highest pedaling loads resulting in direct power transmission. Just what athletes want: Perfect transmission of their power and the reliability allowing them to focus on the ride.
- Material: Aluminum
- Freehub system: Ratchet EXP 36 (36 Points of Engagement = 10º)
Center Lock refers to a system for brake discs that was developed by Shimano. The brake disc is mounted on the hub by means of an external spline and screwing on a lock ring. The advantage of the Center Lock system is that the brake discs are centered and mounting requires only screwing down a single lock ring.
Our hubs are also known for the notool technology. We also found a way to further improve this system and make maintenance even simpler, by a small change of the endcaps.
Freehub Body Conversion
Simplified due to easier disassembly.
Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system what offers an important advantage.
A single cylindrical spring ensures faster full engagement and thus increases reliability.
The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability.
Increased Bearing Lifetime
The integration of the bearing into the threaded ring allows the bearing distance to be maximized. The increased distance further supports the axis, which results in less deflection of the axle and thus protects the bearings and increases their lifetime.
