Hi. I have for sale a never used / never mounted Fox Float R Brain rear shock. Length 7.28" / 185mm and stroke 1.69" / 43mm. It is a shock that fits: 2009/2010 26er S size Epic, 2009/2010 29er Epic and 2009-2010 26r ERA frames. Bushings on this shock are: front are 15.8mm wide for 8mm bolt, rear are 15.8mm wide for 6mm bolt. Bushings might not fit all frame versions but You can always swap these from Your old shock. If You are not sure about fitment just ask me (send me also photo of Your frame / bike) Shocks are 10+ years but are not leaking oil or air so should function well. But keep in mind that so old shock might need quicker service than a fresh one.
