Pros:

• lightweight (approx 4.36g per spoke in 260mm lengths);
• available in silver and black;
• uses standard 2.0 (14g) spoke nipples;
• easier to build with than other thin (eg 1.5mm spokes) because bladed nature means you can see spoke wind up and use a bladed spoke holder to prevent it.

Cons:

• expensive - about 3x the cost of non-aero versions (like DT Swiss Revolutions or Sapim Laser) for no real performance gain when used on a MTB.
