As the name implies, Silicon Tids are M5 size plugs made of lightweight and durable silicone material.
It is mainly used to close bottle holes, etc.
As a water stopcock for unused bottle cage mounts, it is lighter than metal bolts (0.25g per piece), has a low head and is smooth, and fits visually smartly.
In cyclocross competitions that do not require a basic bottle cage, the cycle jersey or elbow may get caught in the head of the bolt when carrying the bike, but it is also effective in preventing such troubles.
