It also works better for tubes that curve in two directions such as round alloy downtubes and carbon tubes that have some curve to them.Module Flex Shields are perfectly sized for Carbon and Alloy downtubes. Our domed bicycle frame protectors feature a 1.25 mm polyurethane dome which absorbs impacts and rebounds to its original shape giving your bike frame maximum protection against the elements. Protect your frame from rocks, sticks, trail and road debris and even that rough tailgate carrier. With just the right amount of flexibility and super strong adhesive, our domed protectors fit to your frame and stay in place!
