Slime Self Healing Road Inner Tube

This is a self-healing Road Bike inner tube that fixes punctures before you even know you've got one!
The inner tube is pre-filled with pucture fixing gloop escapes through holes and solidifies when it contacts the air.
All you need to do is pump a bit more air in occasionally, and although this comes at a cost of a bit of extra weight, it cuts out a lot of hassle!
