BSD Grime Oversized 4pc BarsDenim Cox's signature BSD Grime Oversized Bars are constructed from heat treated, multiple butted 4130 chromoly. They've got a heavyweight aesthetic without being heavy weight. The Grim Oversized Bars utilise BSD's Gorilla Grip system that increases the clamping diameter from 22. 2mm to 25. 4mm adding 14% more clamping area to keep those bars from slipping even when you're nose diving down a 12 stair. ###section### Product Specs Rise: Multiple Options
