SSD Element Enduro Brass Knuckles are a great upgrade option for your Enduro rigs equipped with an IFS (Independent Front Suspension) system. Weighing 80 grams each, these brass steering knuckles add 160g of total unsprung weight to enhance crawling stability and performance by lowering the overall center of gravity. Plus, these knuckles allow the use of 5x11mm outer bearings (included), increasing durability and providing a smoother feel when compared to the stock 5x10mm bearings.
