SHOCK TUBE

Shock Tubes are mostly waterproof vented tubes that fit over the rear shock of a bike and protect it from road salt, water, stone chipping, dust, and dirt. So basically a shock tube helps in filtering out the finer particles that can cause trouble if they get inside the rear side twin shock.

It also provides support to the bike on suspension by providing flexibility so that any jerk on the road doesn't directly harm the bike or the rider.
