Rims, historically are something that don��t really change too much, but with the never-ending evolution of BMX, and ��flybikes�� being a brand to never sit still it was time to freshen up our very popular ��Classic�� rim with some much needed improvements. Besides the strength and obvious design features of the ��Classic�� rim, the new ��Lunar�� rim includes a greater spoke offset for increased stability and refined adjustability, an overall taller shape, deeper rim bed for easier tire installation, thicker sidewall thickness for dent resistance, a rim lip that helps avoid pinch-flats, all rounded out with a perfect 34mm. width. The ��Lunar�� rim has it all!
