Cirrus Bodyfloat

I had tried a Thudbuster but this one had a big advantage in the vertical travel when you need the suspension. The Thudbuster goes backwards some, not vertically up & down.. I read reviews that the Thudbuster eventually squeaks and I could not find a review on the body float that said it squeaks after break-in, I am very happy with the results and my hard tail is much smoother ride. Luna had a great price on it - Thanks Luna Cycle!
