Rim Pillar Spokes Triple Butted Light Weight 26er 27.5 and 29er
Guaranteed Light Weight and Proven Strength
Triple Butted = A tube without a butt has constant wall thickness; it is called a straight gauge tube. A single butted tube is thicker at one end; double butted tubes are thicker at both ends (each end of the same thickness); triple butted tubes have ends of unequal thickness.
Butted tubes are lighter, stronger, and ride better. Butted spokes are lighter and stronger and more reliable than straight-guage spokes. It sounds counter-intuitive to remove metal, yet increase strength, but structures usually fail at the joins, and butted profile tubing helps to distribute stress away from the joins.
