Flat Tyre Defender ET 29 Foam Insert Set

Flat Tyre Defenders specialise in... well... defending you from flat tyres! A simple yet ingenious solution to preventing rim dings on heavy impacts, or having to push home if you rip your rubber.

The dense, closed cell foam tubes sit between the tyre beads and leave plenty of room for sealant on the outside, providing high levels of impact protection for the rim and tyre in the event of deflation or bottoming out. Even when the tyre is completely flat, they can get you home no problem.

Additionally the Flat Tyre Defender will roll over the rim edge with the tyre when subjected to sharp fast cornering, reducing tyre roll and enabling you to maintain your speed with greater control.

The ET series is designed for slimmer rim and tyre widths associated with general cross-country and trail riding, with a 22-27mm inner rim tolerance and 2.00-2.30" tyre tolerance.
