In addition to the dropouts the forks feature tapered and internally butted fork legs, a one piece fully CNC machined steerer tube, fork blade ends relieved for peg clearance and flush inner fork legs for great hub guard clearance. A custom formed fork leg profile also improves fork leg and steerer tube junction strength by adding increased welding surface. ###section### Product Specs Steerer Length: 165mm Wheel Size: 20" Material: 4130 Chromoly Dropout Size: 10mm Offset: 28mm Weight: 961g / 2.11lbs
