Rear Shock Size

Rear Shock Size 29er xc frame
The rear shock size is 165x38mm(standard mount only).
Thanks to the installation position of rear shock on the frame, there is enough rooms to accept the rear shock with piggy back design and coil design.

The rear shock is efficient to steer the bike with confidence to challenge cross country rugged mountain terrain. It also help to absorb the small and large hits with ease, and provides relatively consistent and stable support through the entire adventure.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Bushing Size
Bushing Size cross country bike frame
It's up M8*22.2 mm and down M8*40mm bushing kits as shown for rear shock on this XC MTB bicycle frame. 

Mount kits attach the rear shock to the frame. The eyelet bushings protect the shock eyelet from wear, and help it for better performance.

Linkage-driven Single Pivot Suspension System 
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.
