You are purchasing Sapim Laser double butted spokes in silver.
The Sapim Laser double butted silver is a great spoke for lighter riders that are around 75kg or for building lightweight higher spoke count wheels. It is reasonably priced and offers good bump absorption due to its butted design.
The Laser spoke is best used on wheels where the rider is less than 75kg and weight is more an issue than strength.
Building with Lasers should only be undertaken by experienced wheel builders and the middle section of the spoke needs particular care. You may have to use a suitable tool to hold the spoke to prevent the spokes from winding up.
I’m able to offer these in 1mm increments from 210mm to 310mm.
The Sapim Laser is not rated for use in disc brake wheels, we’d recommend the D-Light or CX-Ray instead.
Here are the tech specs for these spokes:
