This is the 2014 Evolution series shock with open chamber damper cartridge. Not the best design as the damper control piston head is a press fit onto the main body's aluminium shaft (see circled). This usually renders the damper cartridge unserviceable when it comes apart. Challenge accepted. The circle shows the control body after being repaired. This cartridge lived to see another day 👌
The wrong seat height has a huge impact on your body and the balance of your bike. This bike fit was tricky because the client had a pre-existing major right knee injury from a motor bike accident. It meant his knee could not cope with too much knee bend in the closed position.
