Carbon bike mtb frame LCFS917 compatible rear shock


165*45mm, 165*40mm trunnion mount rear shock will work on this frame;165*38mm standard mount rear shock will also work if you install an adaptor.Rear shock mounts in the frame position do not have enough space, not all pig-back design rear shock is applicable. Rockshox Super Deluxe and the DVO Topaz rear shock are workable.However, the air valve of  DVO Topaz is directly in front of the frame and cannot be directly pumped. It is recommended to choose the shock with air vale on either sides of the frame.

Linkage-driven Single Pivot Suspension System 
Cross country mtb frame LCFS917 Linkage-driven Single Pivot Suspension System

Such single pivot suspension system uses an uninterrupted swingarm which connects rear axle directly to the main body of frame. There is no pivot on swingarm, so there is no pivot loosen or noise issue, and the maintenance is simpler. In addition, the stiffness, stability and controllability are greatly improved.The seat stay shaved off at the position in the middle, which helps to reduce vibration and result in better comfortability.
