The French brand Slicy is not yet very well known in this country. But that could change with its Smooth tire insert. This is available in two versions: the normal version for tire widths from 2.3 to 2.6 inches and the Smooth+ version for 2.6 to 3.0 inches. By shortening the length, it fits wheels from 26 to 29 inches.

First impression

Optically and haptically, the Smooth looks like all other puncture protectors of this type. It is 15 millimetres thick and has a recess in the middle area to reduce the weight and allow the sealant to flow freely.

In use

Fitting is very simple: cut the insert to length and connect it with the Velcro tape supplied. Pull one side of the tire onto the rim, insert the Smooth and you're done. Nothing jams and nothing gets in the way, everything is done efficiently. It can even be mastered by people with two left hands, provided they are able to change a tire.

You hardly feel the puncture protection when riding. It has neither a rebound effect nor does it affect the handling when cornering. You only feel slightly less feedback from the ground, as the insert acts like a layer between the ground and the rim and therefore transmits fewer vibrations and oscillations.

With a riding weight of 70 kilos with equipment, an air pressure of less than one bar is possible. Every now and then there was a puncture, but without tire damage or air loss.

It is advisable to check the amount of sealant in the tire a few weeks after fitting. The Smooth absorbs a lot of it and it may well have too little to patch holes in the event of a puncture.

Conclusion

The Slicy Smooth is easier to fit than almost any other tire insert. During six months of use, it has not allowed a puncture and is still in good condition. At around 130 grams per piece in the 29-Plus version, the weight is kept within limits. The protection is top.

Recommendation

With robust tires and a "clean" riding style, you don't necessarily need a protective insert with a tubeless setup. However, there are terrains that demand everything from a rear wheel in particular. Anyone who has ever spent three days or more in Finale Ligure knows that you can hardly survive without a flat tire. The Smooth is the solution for puncture-free days on bike trips like this.
