Cannondale S6 EVO5 Internal Sandblasted Seatbinder The Right Fix for the Right Frame If you own a Super Six EVO Gen 5 and need to replace or service your seat binder this is a OEM replacement part you need. The EVO5's integrated seat tube design routes the binder inside the frame rather than clamping around the outside. This keeps the silhouette clean and eliminates the external collar found on conventional setups. The sandblasted finish on the hardware gives the bolt interface better grip and helps fastener transfer torque more consistently. Ensuring a secure fit, the binder is accessed through the underside of the seat tube with a 4mm hex key.
