The Shadow Sabotage Sprocket is a tribute to an old idea, based on old school sprocket/guard combos, but with new school tech and materials. The high-impact, low-friction plastic guard is paired with a solid 5mm alloy sprocket by 4 bolts. The ultimate in protection for your sprocket and chain, Shadow made the spacing between the guard and the teeth to fit a Shadow Conspiracy Supreme and Interlock chains, which most guards don't do. ###section### Product Specs TYPE: Bolt On MATERIAL: Alloy WEIGHT: 150.3g (5.3oz) Colour: Black, Polished, Skeletor Purple, Crimson Rain; Size: 25T, 28T
