The Stans Flow S1 wheels are strong enough to handle the toughest of trails but light enough to peddle them all day. With a deeper profile and reinforced rim walls, they are able to withstand big impacts with only a minimal weight gain compared to other Flow rims. The 29mm internal width means they are perfect for tyres between 2.35-2.8 inches wide, and they benefit from Stans BST technology which locks tyre beads in place. If you are looking for a wheel that can do it all then look no further than the Flow S1.
