Made from 2 1/2" heavy gauge steel tubing, the NEW Brent Leg Extension Kit is stronger and more sturdy than ever before. Designed to work with Brent B, C, CXC, EX, and ie/ie-x wheels made after January 2009, the Brent Leg Extension Kit raises the wheel from 32 1/2" to 37 1/2" in 1 1/2" increments. It's easy to assemble and adjust. Simply insert the pin into the hole for the desired height on all three leg extensions, tighten the set screws and stand upright. The Brent Leg Extension Kit will also fit other wheel brands with 2 3/8" diameter leg tubes.
