Monocoque body, custom alloy, fully articulating head, absolute length markings, proven easy to use adjustment collars, positive snap-in skinny adapter, modern bend curve, etc. We put it all in our new top end aluminum booms, except the price increase. Pro 1 Alloy booms have exceptional torsional rigidity and fit both standard and reduced diameter masts perfectly. The addition of absolute length markings on a generous 62cm tail-piece aid with rigging your sail properly.

The rounded curve of the 135, 150, 165 model makes hand transitions during jibes, tacks, and the most advanced freestyle moves feel natural.

The Race 185 and 225 has an oversized forged tail for added stiffness but tapers down in the critical grip area. This feature loaded boom also has three pulleys in the outhaul block for in-flight outhaul system compatibility.
