Tubolight Tire Inserts - Gravel

The air channel between the insert and rim acts like a valve and during a shock, some of the air inside the tire moves from the outer portion of the insert into the channel, causing a difference in pressure. As the insert is very tight on the rim, this air gets trapped and takes a fraction of time longer to re-establish even pressure between the outer and inner portion.  That means, in the real world, rolling resistance and tire rebound are reduced.  These two features combined give what every rider is looking for: EFFICIENCY.

Inspired by Tubolight’s MTB insert offering, designed for smoothness with a firmer compound and taller profile for ultimate smoothness on the straights.
