Spokes, or rather the entire spoke assembly, fundamentally affects the overall characteristics of a wheelset. We use exclusively Sapim and DT Swiss spokes for wheel building, and BERD spokes for ultralight and designer wheels.

DT Swiss Aerolite | Sapim CX-Ray
Flat, butted spokes with low weight, excellent aerodynamics and a long service life. These are the best steel spokes you can have on a bike. We consider both spokes equal in terms of quality.
DT Swiss Aero Comp
A bladed spoke that is less butted than the Aerolite and CX-Ray models, weighs slightly more and is somewhat less expensive.
DT Swiss Competition Race | Sapim D-Light
Double-butted round spokes. These are suitable for a more economical version of lightweight wheels. Their weight is very good and they cost about one third as much as the Aerolite and CX-Ray models. The central section of the DT Swiss Competition Race spoke is reduced to 1.6 mm, while the Sapim D-Light is reduced to 1.65 mm.

BERD
Some might say they look like shoelaces :-) In any case, they are spokes made of an ultra-high-density polyethylene fiber that is extremely strong. BERD spokes are also half the weight of the best steel spokes. Another advantage is that they can be easily and attractively colored.
