Pillar XTRA-1422 Triple-Butted Bladed Aero spokes are: 2.0mm|0.95mm*2.2mm|2.0mm.
They are thickest at the elbow (2.0mm) and at the threaded section (2.0mm) – where failures often occur.
The bladed section is 2.2mm wide and 0.95mm thick.
They will fit any standard, round 14G spoke hole and don’t need special slotted hubs.
Breaking Strength: 280 kgf

These spokes can be used with Alloy or Brass external nipples, or with internal alloy nipples or even special locking internal alloy nipples.
Upgrade your external nipples with Taper Grip (Alloy or Brass nipples), for added security.
For added strength, consider M-Power …or go all in and add BOTH!
You can choose to add a little security by adding washers: internal nipples on alloy rims, for internal nipples on carbon rims, or for external nipples on alloy or carbon rims.
Just add 1mm to your calculated spokes lengths.
