Spiral-Butted Tubing

Game-changing tube extrusion technology applied to all MJ Cycle’s aluminium handlebars: more durable, more strength, less weight.

Traditional butting involves a cumbersome 3-step process that does not maximize the potential of aluminum and resulting in compromises. Spiral-butting allows a more dense or compact packing of aluminum material within the tube structure. The result is a significant gain of strength and durability with less weight.

Only MJ Cycle utilizes leading-edge spiral butting technology on handlebars.
