Aeron introduces possibly the stiffest alloy boom on the market. With specialized alloy tempering process, we have arrived at the optimal strength - stiffness ratio. Implementing the tapering technology with the newest ergonomic bends , the result is enhanced rig control and feel that has to be experienced to be believed . Head : With the alloy version, the head is assembled over a high density over molded rubber part to ensure the maximum rigidity while giving grip while rig handling close to the mast cup. Grip Texture : The EVA is thermally formed to produce a texture to improve grip and comfort simultaneously. Formula Racing Tail Housing : Triple pulley cleatable tail is also compatible with adjustable outhaul systems. Adjustment: The single pin U clip is secured over a stainliess pin-this ensures the part has the same locking function even as the boom ages-There is no looseness due to wearing of parts.
