With the growing popularity of Gravel riding and customer requests for Cyclo Cross racing foam inserts, Flat Tire Defender® went to work and designed, developed and tested a ‘true foam rubber insert’ to meet the performance demands and minimize rotating weight for Gravel & Cyclo Cross applications.

Based on Flat Tire Defender field testing, we’ve found on average, tire pressure can be reduced approximately 10% from a tubeless tire pressure without foam inserts.
