Construction: 1-inch O.D. x 0.120"; wall seamless 4130 chromoly tubing. All bends are created with internal mandrels on a CNC bender to reduce flat spots in the radiuses, and all welded joints are precision mitered and TIG welded.

Fitment: Clubman bars were designed decades ago to give bike builders an easy, affordable way to replicate the look and hand position of clip-on bars. Whereas true clip-ons fasten to the fork stanchions below the top triple tree to create an arms-out stance, Clubman bars simply bolt into the risers on your to tree. Years later chopper builders realized Clubman bars could be installed upside-down (welded points facing upward) to give their custom machines "devil horns". Because Clubman bars are reversible, we don't dimple the area where stock H-D hand controls fall. If you want to run upside-down Clubmans on your stock H-D, you'll have to follow the modification instructions features on the tips and tricks page of our website.
Black ED: The black finish on Biltwell handlebars and risers is called Black Electrostatic Discharge or BED, and is applied the same way chrome plate is applied to raw materials. Like chrome plating, powdercoating and standard paint finishes, BED requires periodic care to maintain its luster. Soapy water and a soft cloth will remove surface dirt from BED, and common automotive waxes and polishes work great to protect the finish.
A Few Words on Knurling: We don't knurl our bars because doing so reduces the surface area where the handlebar makes contact with the risers, thereby compromising clamping power. Stock and aftermarket steel risers commonly found on cruisers and custom big twins have a material density 4 times greater than aluminum. This density doesn't let knurling bite into the riser material, which in turn compromises clamping strength.
Please note these are Non-Dimpled bars.
