Aeron's 2021 Carbon Slalom/Race boom range ticks all the boxes with their new ergonomic line up featuring the 170-220, 190-240 and the 220-270 sizes.
The 170 has the traditional inside adjustable tail extension, whilst the 190 & 220 feature outside adjustable tail extensions. All three sizes come with padding on the tail carbon to protect against hard surfaces, removable RDM mast adapter, new boom heads with alloy levers, 27mm oval tube on the 170 and 28mm oval on the 190 & 220 all with ergonomic grip areas, the new diameters all mean stiffer booms with reduced weight. With the addition of the new Loop&Go tail there are now three options for outhaul systems depending on sail and rider preferences.
Sizes and weights are:
170-220 2.6kg
190-240 3.4kg
220-270 3.6kg
