The Original V2 is an enhanced version of the popular Original Insert. It reduces trail chatter, supports sidewalls, allows lower tire pressure, and protects rims. Ideal for lightweight trail, all-mountain, and light enduro riding, it suits shorter travel bikes, smoother riders, and those mindful of weight. The Rimpact Original V2 is easy to install and adds negligible weight, making it an excellent choice to prevent flats and ensure uninterrupted rides.
