The French-to-English translation of Fond de Jante is "bottom of the rim". Which is exactly where the self adhesive Velox rim strips go. It's the only type of rim strip we sell because it's the only type you should put on your wheels. Sure, many wheels these days come complete with their own branded rim strips. Often these are stringy plastic things that offend in every way. Velox on the other hand is perfect in every way. It's inexpensive, it lasts forever, and it's highly effective at shielding your tube from the backside of rim eyelets.
