Fitting a set of tubeless inserts to a road, cyclocross or gravel bike is a great way to ensure that your tyre isn’t going to roll off the rim at low pressures, it adds some protection when riding over rocks and roots, and it means that you can continue riding should your sealant be unable to plug a hole. But branded inserts are very expensive, so we made our own.
